Technologies do not stand still. Mobile devices with which you can easily and quickly go online, are an integral part of each modern man. But what is a tablet without Wi-Fi? Just a piece of plastic and metal. Unfortunately, it often happens that the tablet does not see Wi-Fi. Next, we will look at why it can occur and how to eliminate such problems.

To begin with, it is worth understanding that Wi-Fi technology has different standards and protocols. That is, today there are many different versions Wi-Fi. However, only three standards are used in everyday life:

1. 802.11b is the oldest standard that works at a frequency of 2.4 GHz and has the maximum throughput up to 11 Mbps.
2. 802.11g - standard that was approved in 2003. Allows you to reach data rates up to 54 Mbps. Works at a frequency of 2.4 GHz.
3. 802.11n - the most fast option Wireless communication, which allows you to reach speed up to 300 Mbps. This standard operates at a frequency of 5 GHz.

As you can see, some of the standards work at different frequencies. This means that one of the reasons why the tablet does not see Wi-Fi, it can be in terms of frequencies. That is, if the router only works at 5 GHz frequency, and the tablet supports only 802.11b or G (2.4 GHz) mode, it is not surprising that the gadget cannot see the access point. Here you can already do nothing. Just when buying a tablet, specify its specifications.

It should be noted that many modern routers can work in mixed mode. That is, in the Wi-Fi settings in the router, you can select the 802.11bn mode. This means that the access point will hand out the network immediately at two frequencies, so old, and new mobile devices can be connected to it.

Weak signal

Don't forget that different tablets, like routers, have different antennas. Access point may have a weak antenna, because of which it can cover a rather small area. At the same time, some tablets, by virtue of the characteristics of their design, may have a weak antenna, which is muted by the metal case, which is why the reception will be very weak.

If, for example, a laptop antenna passes around the entire screen, then, of course, the signal level will be very strong. But if an antenna itself is much smaller in the tablet, and even closed with a metal cover, the reception signal will be insufficient. This is another reason why the tablet does not find the Wi-Fi network.

In this case, you should come closer to the router (come closely) and check if the tablet detects this access point. If detects, the problem is in a weak antenna. In this case, you can try to strengthen the antenna. But to do it you will be at your own risk, since not all the ways are simple and safe.

The problem can fade in another. In this case, the source of the difficulty can be both the router itself and the access point to which he tries to connect.

How to determine the problem

Often the tablet does not see Wi-Fi by the fault of the access point itself. One of the reasons was described above (the difference in supported frequencies). But sometimes in order to protect your home network, the owners hide the access point. Therefore, first of all, go to the router parameters and check whether the wireless mode is enabled and the network is hidden. All this is checked in Wi-Fi settings in the router.

If you remove a tick from the first line ("Enable Wireless Broadcast"), then the router will not distribute the network at all. If you remove a tick from the second line ("Enable SSID broadcasting"), the network will be hidden. That is, Wi-Fi will be distributed, but the devices will not see the network name. To such a network, you need to connect to manual mode.

If everything is turned on in the router parameters, it is worth checking if the tablet can see at least one network at all. This is done elementary. Just go to visit friends or in a cafe that has Wi-Fi, and so on. If your tablet sees other networks, then the problem is in your router. If the tablet does not find Wi-Fi network at all anywhere, then the problem is in the tablet.

Solving problems on the side of the router

Maintenance wi-Fi settings-Rueter we have already considered higher. That is, you check which Wi-Fi mode uses a router, and whether wireless broadcast is included, and whether the network is not hidden. If all these parameters are in order, then you can not configure anything else. In this case, you should restart the access point. Just disconnect the router from the outlet for 7-10 minutes, then turn on again.

If, after that, the tablet does not see the Wi-Fi network, then you should do to the factory parameters. If it does not help, you will have to update according to, since, most likely, some kind of failure in the system has occurred. Instructions for updating software, like the firmware itself, you can find on the official website of the router manufacturer. If even the software update does not help, you will have to buy a new router. When choosing, pay attention to what modes and wi-Fi standards Supports access point.

Problem on the side of the tablet

If you have determined that the problem lies in exactly the tablet, that is, it does not see any network at all and does not go online even in close proximity to access points, there are several options here.

First of all, you should simply restart the device. The fact is that due to the accumulated cache (garbage), the tablet may not include a wireless adapter at all, which is why the search for networks does not even start. That is, the tablet does not catch Wi-Fi. The reboot resets the cache and restores minor failures in the system.

If this does not help, then you should move to more cardinal measures. Immediately it is worth saying that the Android system is arranged in such a way that there are no settings like on a PC. You cannot reinstall drivers for Wi-Fi-adapter, reset network settings or configure a network adapter. Connecting to networks occurs automatically. Therefore, if nothing of the above helps, you will have to relieve the factory parameters.

Another reason why does not catch Wi-Fi on the tablet, it may be that the antenna terminal moved away from the fall (probably there is no such tablet, which never fell). Also, contacts could oxidize due to high humidity or if the device was disassembled to repair, then when assembling the wizard, the wizard could have forgotten to connect the antenna. In this case, you need to disassemble the gadget: check if the antenna is connected and clear the contacts.

Of course, such reasons arise extremely rarely, but still they should be considered. Also, do not forget that sometimes due to intensive work, the network adapter can simply burn. You can't check this at home, and without such an adapter, the tablet, it goes without saying, will not be able to go online. Therefore, if you tried all the available measures, and nothing helped to correct the problem, it's time to carry your gadget for repair.

How to configure Wi-Fi on the tablet: video

Thanks to the growing speed, more and more tablets are equipped with GSM or 3G modules, getting the opportunity to enter the network always and everywhere, and not only in the Wi-Fi area. However, with the appearance in tablet computers, the connectors for SIM cards originated and a fairly typical problem: the tablet does not see the SIM card.

When PO is guilty

Gadget software can also be the cause of the absence of the Internet. For example, if after the network suddenly disappeared, then, with a high probability, the reason was exactly the downloaded program. Try it to simply remove it.

And sometimes everything is fault by the user's inattention: accidentally activated the "airplane" or "autonomous" mode. In this case, it is necessary to check in the device settings that mobile networks are enabled and data transmission is allowed. There see if the priority is not specified: in this case, the mobile Internet may not work, despite the defined card.

Another reason may be a system firmware failure. In this case, it will probably help or, in more severe cases, hard reset (remember that full reset Custom settings will be lost all information on the tablet, so it is pre-made a backup).

A common situation among when the device sees a SIM card, but it does not connect to the mobile network. Most likely, parameters for native Chinese operators are set in the settings of mobile networks. You must specify your mobile operator Or, if it is not in the list and is not when searching, manually set the parameters of the APN and the others you need to connect (you can find on the operator's website, in the communication salon or by calling technical support).

Let's sum up

So what to do if the tablet writes "no SIM card"? Here is a brief algorithm:

• check if the mode "in an airplane" or "autonomous" is not activated;
• if the Internet stopped working after installing new applications, remove them;
• check Settings mobile networks;
• check the SIM card on another device (tablet or smartphone);
• if everything is fine with the card, check the SIM reader connector using another SIM card (preferably another operator) -, attribute the tablet in service center To replace slot and loop;
• if the connector works and sees a map of another operator, replace its SIM in the communication salon;
• if the network does not appear with a new card, make a hard reset or;
• if all of the above did not help - direct road to service.

We hope that thanks to these advice, you will no longer have to confuse the back of the back when you are disconnected and you can solve the problem in most cases.

After purchasing the tablet, you will most likely want to use the wireless link. Often, users find themselves in a situation where the device does not see the network or gives a number of errors when connected. In this article, we will consider the most common problems that arise when entering the Internet and ways to solve them.

Why the tablet does not connect to the wireless network

1. Introduction of the wrong password

The most common cause of wireless Internet utilization on the tablet. Most often it occurs if the user has changed the password, and the Android device has never been connected to it. Enter the new password and check whether the device connects to the Internet.

2. Viruses

Sometimes the reason why the device does not connect to the Internet may be an impact malicious programs. To eliminate this problem, you must scan antivirus gadget.

3. Failure to power

For inexpensive routers, unstable work is characteristic. Racing in voltage can lead to the fact that the tablet does not see the network. To solve the problem, restart the router, disconnecting it from voltage for 2-3 minutes. Then turn on again. Sometimes a reboot must be done several times.

4. Incorrect encryption type

To check the encryption type, go to the router settings. To do this in the browser's address bar, enter the IP address of the router. This data can be viewed on the device sticker or in the instructions. In the tab that opens, select "Extended Settings". Then in the "Wi-Fi" section, click Safety Settings. To see the encryption type, go to the "Network Authentication" menu. From the proposed options, select WPA-PSK \\ WPA2-PSK2 Mixed. Restart the router. 5. Incorrect time settings and date

In some cases, the tablet does not connect to wireless network Due to incorrect dates and time values. After fixing these parameters, to resume the correct operation of the network.

6. Checking MAC-filter mode

Another reason for which the user on the tablet does not see Wi-Fi, can be changes to the filtering settings of MAC addresses. To exclude this option in the router parameters in the "Wi-Fi" section, go to the MAS-Filter item. Check which mode is selected. The following values \u200b\u200bare possible:

• Disabled - by default, no restrictions for MAC addresses.
• Allow - access to the wireless network is allowed only to those devices whose MAC addresses are written on the corresponding tab. Other devices access to the Internet is prohibited.

Prohibit - there is a list of MAC addresses, which are limited access to the Internet. If the router sees the forbidden MAC address, it closes the device to Wi-Fi for this device.

If you select "Allow" or "prohibit" in the router settings, check whether access to the MAC address of your device to the wireless network is open. Either change the mode to "disabled". After these manipulations, check how the gadget connects to the network.

7. Diagnosis of channels

If the tablet sees the network, but does not connect to it, check the correspondence of the channels. This problem occurs when the signals of two routers running on the same channel intersect. There are interference that closing access to the wireless network.

Look on your tablet, is there any other wireless networks. If your neighbors have Wi-Fi, then perhaps your routers work at one frequency.

To change the channel in the router settings, go to the "Wi-Fi" section to the "Basic Settings" tab. Find the "Channel" string, try to select another value.

Restart the router.

If the settings have a channel in Auto mode (AUTO), the router will search for an affordable free channel and use it. Therefore, in most cases it is recommended to use this mode.

8. Changing Wi-Fi version

The reason why the tablet does not see the wireless network, it may be that it does not support the version wireless communicationwhich is installed in the router settings. On the Wi-Fi tab, go to "Basic Settings". In the "Wireless Mode" string, slide 802.11b \\ g \\ Mixed. In this mode, the router provides Internet access for all types of devices.

What if the tablet sees the network and connects, but the connection is unstable

• Try connecting the device to another router and check whether the connection is stable. If the connection is stable, then the problem is in the home router.
• If during the output of the Internet on the tablet, charging was taken, and it is connected to the power supply, check the connection when the adapter is turned off. The malfunction of the power supply can lead to wireless communications problems.

If nothing helped look at this video and repeat:

If you have taken advantage of the following advice, but the device still does not see the network, refer to the specialists. It may be necessary to reflash the tablet or router.

A modern tablet is difficult to imagine without Wi-Fi module. However, sometimes the user faces a problem in which the tablet does not see Wi-Fi. What could be the causes?

1. The first reason that immediately comes to mind is a weak signal due to constructive features Gadget. In contrast to the laptop antenna, the Wi-Fi-antenna of the tablet has smaller sizes and can be covered with a metal cover, which can significantly weaken the received signal.

Decision: Place the tablet in close proximity to the router or try to enhance the signal.

Search Wi-Fi in iPad

2. The operation of the router at a frequency not supported by the tablet may cause the tablet not see the Wi-Fi access point. There are three main standards: 802.11b, 802.11g and 802.11n. Despite the fact that many routers are capable of working in a mixed mode, providing data transmission at all possible frequencies, some network devices support only one data transfer standard. Let's say 5 GHz. And the tablet works only by 2.4 GHz (802.11b or 802.11g). Of course, the tablet will never see Wi-Fi.

Decision: To find out in detail the characteristics of the tablet before buying, make sure that the router and the tablet in terms of supported Wi-Fi protocols are compatible.

3. The reason may also conclude that the access point was hidden by its owner.

Decision: Change the router settings so that the access point is no longer hidden. At the same time it is worth checking whether the wireless mode is enabled. There may be a general rule. In the settings of many routers there is an "Enable SSID broadcast". If you remove a tick with this setting, the network will become hidden. Opposite the setup "Enable Wireless Broadcast" should also stand a daw - in this case the wireless connection will be allowed as such.

4. The reason may come in the router itself. Here are several ways to solve the problem.

Cause

Decision №1: Reload the router.

Decision number 2.: Rollback of the network device to the factory settings.

Decision number 3.: reflash the router by downloading last version Firmware from the official content of the device manufacturer.

Decision number 4.: Buy a new router, if nothing about the above helped.

5. Cause of the fact that the planets does not see Wi-Fi can also walk in the tablet. Here you can also consistently try to resolve it in several ways.

Cause: hanging the router or failure in its work.

Decision №1: Reload the gadget, with the result that the cache will clear and disappear some errors in the system.

Decision number 2.: Reset the gadget settings to factory. This measure is cardinal, but without it, it happens, not to do. The fact is that, unlike Windows, with its flexible network settingsThe Android operating system will not allow reinstalling drivers for a Wi-Fi module, reset network settings or configure the network adapter. Android devices, as a rule, are connected to the access point in automatic mode.

Other reasons: Routher malfunctions as a result of physical impact, namely:

1. Antenna failure due to the fall of the gadget.
2. The oxidation of its contacts in high humidity conditions.
3. The negligence of the wizard during repair work when he forgets to connect the antenna.

Decision: Open the tablet case and:

1. Make sure the antenna is connected.
2. If there are traces of the oxidation of contacts, clean them.

Cause: The failure of the network adapter of the tablet as a result of its burnout due to overloads in its operation.

Decision: Maybe only one thing is to carry the tablet to repair and continue to prevent the device overloads.

How to determine the problem in the router or tablet?

If your tablet does not see Wi-Fi in the home network, then check whether your tablet connects to the network elsewhere, for example, to any free access point on the street or in a cafe. You can also check this away from a friend or girlfriend who have Wi-Fi.

If it does not help - it means that the malfunction lies in the hardware and eliminate it at home will not be released.

Of course, in the network you can find videos and descriptions, as the owners of the non-working device "baked" Wi-Fi modules in the oven, after which they came to it. But this method is not a panacea, and he cannot eliminate all the faults. In practice, the ordinary user creates even more breakdowns, trying to disassemble the tablet, not to mention the successful repair "folk methods". So, when the hardware breakdown is a visit to the service center.

The main reasons why WiFi does not work on the tablet

After the "opening", the specialist will announce the cause of the breakdown. It can be:

• Natural wear module: In this case, it simply changes to a similar one.
• Worn up the loop connecting the wireless communication module with system board Tablet. In this case, it is also subject to replacement.
• Water getting inside the case. An extremely dangerous situation, since after Wi-Fi may fail and other equipment.

All these problems are easily eliminated by employees of the service center. The sooner you see for help, it will be better for you for you for the tablet.

In this article we will talk about such a common problem what to do if the tablet does not connect to the wireless WiFi network. This is up to date the topic today, as the tablets are enjoyable distribution worldwide. In addition, problems with connecting to wireless networks appear quite often and not everyone is able to solve them independently.

So, speaking of a wireless network, it is worth understanding that we are talking about a WiFi router or another point of access. It is worth noting that for security purposes, such connections require key administration. This means that the first thing if the WiFi network does not connect on the tablet, you should check the correctness of the password.

As mentioned above, the most common error is an incorrectly entered password.

However, other problems associated directly with wireless equipment and its settings are found. These include the following:

• Mac filter is installed in the router settings.
• Failures in the router.
• Non-compliance of encryption types.
• Channel inconsistencies.

It is worth noting that there is nothing to customize anything in the tablet. All that can affect the connection is concluded in the router settings. That we will go to troubleshoot. And first of all, it should be paid to the fact that budget routers, such as TP-Link, D-Link. Asus, Zyxel and so on, do not differ in high stability of work. They have a tendency to hang.

This can occur for many reasons, for example, due to interruptions in the power supply network, strong load (if you swing large amounts of information at high speed), as a result of connection large number subscribers and so on. In any case, you should restart the router. How it's done. Everything is simple. Disconnect the device from the power supply and wait 7-10 minutes, then turn it on again.

Checking the encryption type

If the tablet does not connect to WiFi and writes "saved", this indicates the inconsistency of encryption types. First of all, you should know that modern wifi. Devices support WPA-PSKWPA2-PSK2 Mixed encryption type. If you select another mode on the router, then the tablet is simply and, accordingly, connect. In other words, the tablet sees WiFi wireless network but does not connect to it.

So, we need to enter the router settings. To do this, connect to it using a laptop (via WiFi or through a cable). Next, open any browser and in the address bar We write an IP router. The desired data is available on the device itself or in the instructions. If you do not have a manual, there are no data on the router housing, then open the command prompt. To do this, simultaneously press the Windows + R keys, in the window that appears, write CMD and press "ENTER".

In the opened menu, write the ipconfig command and press "ENTER". Now you need to find the "Main Gateway" string. This is the data we need.

As a rule, it is 192.168.0.1, but depending on the router model, these values \u200b\u200bmay differ. So, we prescribe the received data in the browser, after which the system will ask you to enter a login and password. We write admin, admin, respectively.

How easy to find out the IP address of the router: video

So we got into the router settings menu. It is worth noting that depending on the device model, the interface may differ. Also differences may be in the names of some sections. Consider further actions on the example of the D-LinkDir-615 router.

In the router parameters at the bottom of the screen, click the "Advanced Settings" button. Find a section called WiFi. Here you click "Security Settings". Here the first line "Network Authentication" is a type of encryption. Select from the proposed WPA-PSKWPA2-PSK2 Mixed options and apply the changes. After that restart the router.

Often, a similar error occurs and with a properly installed type of authentication. In this case, you will help reboot the router. As mentioned above, budget models do not differ in stability in the work.

Check MAC filter

Answer to the question why not connect WiFi Network The tablet lies in the filtering settings of Mc addresses. The fact is that a special function is activated to enhance protection, which determines physical adress Computer, opening or closing access to it. To check this, you should return to the router settings. In the WiFi section, select Mac Filter.

In order for you, you do not have any problems in the future, you should turn off the filtering.

But if you do not want to do this, we do the following. In the beginning we look at what kind of mode is selected:

• Allow - the router allows access to only the specified devices.
• To prohibit - the router blocks access to the network specified tablets.

Now it remains only to learn the physical address of your tablet and check if it is in the list and, if necessary, add or delete it.

Check channels

If you have turned off the filtering, and the tablet still sees the WiFi network, but does not connect to it, then go to the next step. This problem often arises due to channel inconsistencies. So let's return to the router settings and try to change them.

To do this, go back on the access point parameters and in WiFi section, select "Basic Settings". Here we need to find the line "Channel". Try to change it on some other. It should be noted that it is recommended to install the "Auto" mode. Thanks to this, the router will automatically use the most appropriate channel.

1. Error authentication

This trouble is one of the most frequent, but easily solved.

Solution: Enter the correct password

Yes, Dae, dear readers, such an error is associated with an error in the password. Try checking the correctness of writing, register of letters and to the network you connect from which you have a password.

2. Does not find the Wi-Fi point

The root of the evil in the mismatch of the data transmission mode, which is used by the device, and the standard of the router. For communication, three modes can be used for modern routers: 802.11b, 802.11g, 802.11n. True, Wi-Fi mobile gadgets usually functions only in one of them. If the tablet works with the 802.11b Veriant, and the network, for example, with any other, then it will simply not see it.

Solution: change the broadcast standard

Fortunately, in most cases, you even do not even need to know which mode of operation is installed in your device. In any router there is a fourth standard, which is called 802.11b / G / N Mixed, it combines all three options in one. When using it, any device will be connected without any problems and will delight its owner access to the Internet.

In a nutshell, I will tell you how to configure the access point. To do this, you will need a computer that is already connected to the network you need. Print in the address bar of your favorite browser 192.168.0.1 or 192.168.1.1, this will cause a router page that requests password and login. As a rule, the word "admin" is used in both lines. After hitting the user interface, you need to find the item, with control, there will be the option of changing the wireless module mode.

3. Cannot get a network address

There may be a situation where the access point does the device sees, but it can not connect to it.

Solution: specify static IP

In the list of available connections, find the right one, then click on it and hold until the pop-up menu appears. We are interested in the item "Edit Network".

Tick \u200b\u200bthe checkbox " Extra options"And then change the" IPv4 setting "column" DHCP "parameter to the" static ". True, it's not all, check the code to fully correspond to the lower column "Gateway" in the IPv4 address point, except for the last number, you can think of it, but only in the range from 2 to 255. Do not forget to verify that everything The numbers are separated by points, that's how in this example: "192.168.1.128".

Description:
To date, wireless networks help not fall out of sight and constantly stay in touch, opening access to the Internet and providing a reliable connection with various devices. And although during its existence, Wi-Fi has almost made perfection, but still remained quite a capricious type of communication. The problems that arise in connection with this are practically identical for phones, computers and tablets. Most often, this is a network without access to the Internet, there is no access to sites if there is a connection and a phone or tablet does not connect to Wi-Fi Router.
To date, wireless networks help not fall out of sight and constantly stay in touch, opening access to the Internet and ensuring a reliable connection to various devices. And although during its existence, Wi-Fi has almost made perfection, but still remained quite a capricious type of communication. The problems that arise in connection with this are practically identical for phones, computers and tablets. Most often, this is a network without access to the Internet, there is no access to sites if there is a connection and a phone or tablet does not connect to Wi-Fi Router.
How to properly connect the tablet to a Wi-Fi router? To do this, make the following actions:
1. Check Wi-Fi settings on the router itself, making sure that the wireless network is activated, and the DHCP is connected. This will avoid the need to prescribe an IP address with each subsequent connection.
2. Go to the tablet settings, turn on Wi-Fi, cluster the Wi-Fi icon for a few seconds and go to the wireless network settings.
3. In the list of available networks, select the router (if necessary, enter a password).
4. Click "Connect".
If for some reason there was a need to manually register the IP settings, you must put a tick in the "Advance" string. This will open access to the advanced settings. Over the opposite "IP settings", choose "Custom". In the window that opens, you must specify the IP of the router, which in this subnet will act as a DNS server. After that, you can connect.
If you did everything right, but tablet Samsung Or the other does not connect to the WiFi router, that is, several ways to solve this problem.
If the tablet does not connect to Wi-Fi before contacting the service center, you can:
1. Check whether Wi-Fi is connected on the tablet itself.
2. Check if the power is powered.
3. Check whether the filtering function is activated by the MAC address in the router settings.
4. Connect to an open access point. After turning off WPA encryption.
There are situations where the tablet "loses" communication with a Wi-Fi point. Of course, for each user, this is a rather unpleasant situation. As a rule, it happens at the most inopportune moment. Several recommendations will allow the user to independently cope with this problem.
If the connection between the tablet and the Wi-Fi point is broken by:
1. Switch to another Wi-Fi point. If after that the problem will disappear, then the cause of trouble lies at your access point. In this case, you can change the network settings or update the firmware of the connected device.
2. Connect to any other open access point, for example, to a neighbor or choose a less used channel.
3. The reason may be in the device adapter. In some cases, the faulty adapter creates interference, which is the cause of the "loss" of the connection between the router and the tablet.
We hope that these recommendations will allow you to avoid a situation where the tablet does not connect to the WiFi Zyxel Routeer, Rostelecom, Beeline or Asus, and if such a trouble happens, to cope with it.

Today, it is already obvious for everyone that if the tablet or smartphone does not connect to the Internet via WiFi, then immediately for the user is lost most of the entire functionality of this device. Connecting the device to a wireless network is usually not accompanied by difficulties, you simply need to turn on the adapter-adapter gadget to the gadget and then connect to the selected access point by writing a password.

However, sometimes wifi, i.e. to enter the Internet through Wi-Fi, it does not work because of some problems. Below are the most frequent reasons why the tablet does not connect to WiFi, as well as specific recommendations, what to do if the gadget owner faced such a situation, on the example tablet Lenovo.which does not connect to WiFi wireless network. IN tablet computer Sometimes WiFi is not included both due to the presence of problems in the device itself and due to the failures of the network equipment.

The owners of Lenovo gadgets are very rarely found with WiFi problems in the device itself, but if this function does not work, it happens that many causes of problems are very quickly solved by users of simple adjustments of some settings.

It is important to write password carefully

Very often, the owner of the tablet itself is the culprit, why the fully suitable device is connected to the wireless access point. Many cases when Wi Fi on the tablet is not connected due to incorrect writing code for network access. Currently, the Wi-Fi network security setting is very common, for example, using WPA2 protection. It is recommended to set a mark on the page "Show password" during the access code set. This in most cases provides an errorless writing of the password.

In the case of absolute confidence of an accurate recruitment of the password, and at the same time it cannot be turned on the Internet, it is required to check the operation of the router first. Often difficulties are manifested due to incorrect settings of the router, its overload, voltage jumps in the power supply network, etc.

Restarting router

In the case when the tablet or smartphone Lenovo. Or another brand does not connect to WiFi wireless network, the message immediately displays the message. You need to restart the router to which the user intends to connect. In most cases, after this procedure, the Internet begins to function normally in the device.

Analysis of the security system of the secure network Wi-Fi

When the gadget cannot establish a connection to the router and, in this case, it is saved in the status bar, then you can conclude about the various types of coding used by the router and device.

You must perform the following sequential steps:

Mac-Address Settings

Most often errors when filtering MAC addresses appear when the tablets are working with Lenovo manufacturers and asus with cheap router models. These gadgets in order to ensure maximum security determine the MAC address and in the case when it is not defined, then exit global Network It is overlapped, which is often a problem why access to the network is not included in the tablet.

It is necessary to take the following steps:

If it was not successful to solve the problem, it is necessary to try temporarily in the "Network" tab to turn off filtering. And restart both devices.

Check channels

With absence positive result After performing all the steps described above, it is recommended to set the channels.

This requires to perform the following actions:

1. Enter the router settings;
2. In the chanel point to change the value (it is advisable to try all possible values). After specifying one of the modes, it is necessary to click "Save";
3. Next restart the router and tablet computer;
4. Make an attempt to connect.

When unsuccessful, all attempts will have to resort to the discharge of tablet PC settings.

Incorrectly installed connection mode

It happens that the router and the tablet use various modifications of communication on Wi-Fi. In this case, the device does not specify the version used by the router.

There is the most popular version of the connection 802.11n, as well as with the prefix "B" and "G".

It is necessary to produce the following steps:

1. Open the router settings menu;
2. View the connection version and, if necessary, change it to the appropriate tablet software;
3. Restart devices;
4. Test the functionality of all modes.

Description:
To date, wireless networks help not fall out of sight and constantly stay in touch, opening access to the Internet and providing a reliable connection with various devices. And although during its existence, Wi-Fi has almost made perfection, but still remained quite a capricious type of communication. The problems that arise in connection with this are practically identical for phones, computers and tablets. Most often, this is a network without access to the Internet, there is no access to sites if there is a connection and a phone or tablet does not connect to Wi-Fi Router.
To date, wireless networks help not fall out of sight and constantly stay in touch, opening access to the Internet and providing a reliable connection with various devices. And although during its existence, Wi-Fi has almost made perfection, but still remained quite a capricious type of communication. The problems that arise in connection with this are practically identical for phones, computers and tablets. Most often, this is a network without access to the Internet, there is no access to sites if there is a connection and a phone or tablet does not connect to Wi-Fi Router.
How to connect the tablet to Wi-Fi Router? To do this, make the following actions:
1. Check Wi-Fi settings on the router itself, making sure that the wireless network is activated, and the DHCP is connected. This will avoid the need to prescribe an IP address with each subsequent connection.
2. Go to the tablet settings, turn on Wi-Fi, cluster the Wi-Fi icon for a few seconds and go to the wireless network settings.
3. In the list network available Select the router (I will enter a password if necessary).
4. Click "Connect".
If for some reason there was a need to manually register the IP settings, you must put a tick in the "Advance" string. This will open access to the advanced settings. Over the opposite "IP settings", choose "Custom". In the window that opens, you must specify the IP of the router, which in this subnet will act as a DNS server. After that, you can connect.
If you are all done correctly, and the SAMSUNG tablet or another does not connect to the WiFi router, that is, several ways to solve this problem.
If the tablet does not connect to Wi-Fi before contacting the service center, you can:
1. Check whether Wi-Fi is connected on the tablet itself.
2. Check if the power is powered.
3. Check whether the filtering function is activated by the MAC address in the router settings.
4. Connect to an open access point. After turning off WPA encryption.
There are situations where the tablet "loses" communication with a Wi-Fi point. Of course, for each user, this is a rather unpleasant situation. As a rule, it happens at the most inopportune moment. Several recommendations will allow the user to independently cope with this problem.
If the connection between the tablet and the Wi-Fi point is broken by:
1. Switch to another wi-Fi point. If after that the problem will disappear, then the cause of trouble lies at your access point. In this case, you can change the network settings or update the firmware of the connected device.
2. Connect to any other open access point, for example, to a neighbor or choose a less used channel.
3. The reason may be in the device adapter. In some cases, the faulty adapter creates interference, which is the cause of the "loss" of the connection between the router and the tablet.
We hope that these recommendations will allow you to avoid the situation when the tablet does not connect to WiFi zyxel router, Rostelecom, Beeline or Asus, and if such a trouble happens, to cope with it.

Enthusiasts are reverent to the router. Copy the settings, fearing unauthorized access, complement the wireless interface by restricting the MAC address. This figure is not unique. Separate programs, including accessories of Windows allow you to change the number, however ... specially home how to make it becoming more likely. Therefore, the filter of MAC addresses remains effective protection. True ... someone else's tablet is not connected.

Online Stttit "Delicious" Soviets, like:

1. Enter password anew.
2. Change the encryption type (AES), protection (WPA), key.
3. Restart the phone, router, tablet, brains.
4. Try the device to another brand: samsung, lenovo ...

This can be done only from despair. When the brain stopped working ...

Administrator panel

The lion's share is eliminated by the admin panel. Avoid updating with Wi-Fi, try to connect the cable:

1. Open the browser.
2. Enter the address of the local router admin panel (192.168.0.1, 192.168.1.1), login, password.

Filter router

Teach you to check the settings, using typical example D-Link. Localization inside the admin panel may differ significantly. Patiently look for the desired section.

1. Enter the admin panel.
2. The filter usually concerns only a wireless interface (Wi-Fi, Wireless). The list of connected cable is obvious.

The model of the router supports two modes:

• Ban (black list).
• Permission (white list).

Check out existing settings, Reset, add. We remind you: anyone operating system (Android, iOS) will solve the MAC address. Even sometimes you can change the value. Using the phone menu, set the prohibitions, permissions.

Channel loading

New software The router analyzes the loading of the channels. Check out available, select Free Numbers.

Alternative option - download third-party products that perform similar work. The screen shows a small loading of the first three channels permitted by the Russian Federation. Apple Corporation Recommends: In the 2.4 GHz band, it is necessary to set the width of the channel of 20 MHz (not supported by the old gland). The 5 GHz region is deprived of these limitations.

It is interesting! Typically, the router automatically selects the minimum occupied frequencies. Therefore, the tips change the room is often caused by hopelessness.

Regional belonging

There are devices of other regional affiliation. Old routers ignore the legislation at all, the newly adjust the list of available channels according to the specified country. Check the reason may be the inconsistency of regional settings. Change the country, exhibiting, for example, the United States.

Unproved, but the device may well change the signal level according to the legislation. After all, the number of channels tracks. The level approximately shows the scale of the tablet itself. Try.

Authentication error

The problem concerns the case of incorrect password entry. Check out two items:

1. The correctness of the access point name.
2. Compliance with the alphanumeric key combination set.

Protocol version

The IEEE Committee is constantly improving the standard. Today, the range of 60 GHz is actively mastered. Ensure maximum compatibility by selecting the router (Mixed) options among the router settings:

• 11 b / g / n Mixed.
• 11 G / N Mixed.

The chance of inconsistencies sharply falls.

Number of subscribers

It happens, the smartphone sees the Internet, laptop asus Connects, tablet - does not want to boil the network. Check the limit by the number of simultaneously connected subscribers:

1. Visit the admin panel.
2. In the marks to Wi-Fi, find out the number of connected subscribers simultaneously.

Even if the number is less than the number of devices, remember the omnipresent neighbors. Rarely attackers live nearby, they could come accidentally, occupying a dedicated resource. Figure 0 usually shows the absence of restrictions.

Try to increase the limit. First - make endless, then follow the circumstances. Earned - start lowering the volume. New modifications do not show the network card, displaying connected devices. Immediately becomes obvious location of breakage (router, or tablet).

The map will help to identify the fact of unauthorized penetration from the phone of the neighbor ...

Saved ...

It happens, writes: "Saved in memory. Type of protection WPA / WPA2 ... ". Break down to come closer, taking a tablet. You will first see the inscription "Connection ...", then "Obtaining an IP address ...", finally, "connected". This means a small signal level at the beginning. Therefore, the network does not work.

Then take the newly cozy chair - the connection will be saved. It will interrupt - you have to take the device again, bring closer.

Signal level

The item is closely related to the previous one. Separate routers allow you to set the signal level, the situation is able to correct the external antenna. The power of the transmitter is limited, so the radiation will not be increasing infinitely. Sometimes you have to use external antennas.

Change SSID

Old routers had a unified SSID. Simultaneous operation of several such devices nearby with different passwords are impossible. Weak phones usually catch the nearest access point, Windows refuses to display more than one network with the same SSID. Noticing the problem, change the name. Let it be clearly unique. Otherwise, an attempt to connect to a neighbor, a password, of course, is unknown.
