Does your tablet not see the Wi-Fi network, or is the connection failing? Is the signal weak or unstable? One or more problems indicate that there is a problem with the mobile device and/or network equipment. To solve the problem, we have prepared an exhaustive material, where you will find the cause and how to fix the breakdown.

How to identify a malfunction

When using the Internet, the chain consists of a provider, network equipment and a user device. Therefore, in order to quickly resolve problems, it is important to determine on which side the malfunction occurred.

Find out if there are any interruptions in the availability of the Internet from the provider. To do this, connect an Ethernet cable to network map computer or laptop. If this is not possible, call the provider and ask if there are any interruptions in the Internet at your address.

Connect another device to the router, preferably with the same Wi-Fi module specification. If other equipment connects and works properly, the problem should be considered in the mobile device.

Connect tablet to other points WiFi access. A failed connection indicates a problem with mobile device. If the connection cannot be made only with a home router, then the problem must be sought in the equipment used.

What to do when there are problems on the provider side

Solution 1: report the problem to the Internet provider, replace the Ethernet cable

If there is no internet, report the problem to your service provider. If the breakdown cannot be solved remotely, call the wizard home, for example, to replace the Ethernet cable. A reason to think about replacing if you live in apartment building, and the cable is routed outside. It is important to note that most providers have tools for remotely diagnosing cable integrity.

Solution 2: Check modem/settings

If the Internet is provided via a telephone line, check the operation of the modem. Connect the equipment directly to a PC or laptop, check the connection settings. If there is no result, take the modem to the service center for diagnostics.

What to do with problems in the router

Solution 1: Restart your router

The router is a miniature computer, so failures and system errors during operation are unavoidable. In this case, the problem is solved by restarting the system. It is advisable to turn off the power for 2-3 minutes.

Solution 2: Check your internet settings

For the Internet to work correctly, you must set correct settings in the management console. The procedure is required if the router is configured for the first time. Periodically, the parameters should be rechecked, as failures often lead to resetting the settings.

Solution 3: enable Internet distribution over a wireless network, DHCP protocol

In the settings, it is important to activate the "wireless broadcasting of the router" and "broadcasting SSID" functions. Also enable the DHCP protocol, if the option was not activated earlier.

Solution 4: Change channel

If a fixed channel is set in the router settings, it is recommended to change the value or set the mode to auto. If it is used auto mode, reboot the router to automatically change to a less loaded channel.

Solution 5: Switch broadcast band

Some routers allow you to work in only one or two broadcast bands - 2.4 / 5 GHz. If the frequency range of the router and tablet does not match, the connection will fail. Therefore, set the frequency supported by the tablet in the router settings.

Solution 6: Disable MAC Blocking

Sometimes, when blocking unwanted consumers, it is easy to mistakenly add your own tablet to the blacklist, which will not allow you to connect to the Wi-Fi network. If there are blocked MAC addresses in the list of the router, find out the corresponding value in wifi settings. Verify the data, and if necessary, remove the MAC address from the blacklist.

Solution 7: Reduce Load/Temperature

Using a Wi-Fi network will not work if the router is loaded with another connected device - a PC or laptop. Then you need to limit the speed or temporarily stop downloading / uploading information.

Take care of acceptable temperature regime. If the router is overheating, consider active or passive cooling.

Solution 8: Increase transmitter power

If the access point appears and disappears from the “available for connection” list, or the connection is lost after connecting, the transmitter power is probably muted. Open the router settings and increase the level of the transmitter. If the antennas of the router are of a replaceable type, install the reinforced version.

Solution 9: Reset Router/Update Firmware

Sometimes viruses and system failures do not allow you to change settings. When changing parameters, the values ​​are saved, and after switching to other settings, they return to starting position which makes the setting pointless. In this case, it is recommended to set the parameters manually from scratch.

If the reset did not affect the operation of the router, then it is worth updating the firmware. If there is no result, take the router in for repair or think about buying a new device.

What to do if there is a problem with the tablet

Solution 1: Check if the entered password is correct

A common mistake when connecting to an access point is the wrong password. By default, the tablet settings are set to “hidden password”, which makes it easy to make mistakes when entering. Therefore, it is recommended to allow the display of the password, as well as to be case-sensitive when entering characters.

Solution 2: Reboot the system

Sometimes the tablet experiences a system failure that prevents it from connecting to the network, or the connection is successful, but there is no Internet access. In this case, restarting the operating system usually helps.

Solution 3: Disable Power Saving Features

To save energy, most tablets are equipped with power saving modes. Usually, the effect is achieved by disabling modules that actively waste power, including Wi-Fi. Therefore, it is recommended to deactivate the corresponding mode or use a performance preset.

Solution 4: Change the broadcast band / turn on the display of networks with a weak signal

If the tablet is designed to work with the 2.4 and 5 GHz bands, it is recommended to set the automatic band selection. Also, do not use the option “Hide access points with a weak signal”, because with a weak signal from the router, you will not be able to connect.

Solution 5: Change Firmware/Radio Module

often improve Wi-Fi operation It helps to change the firmware or radio module. If problems with connecting to Wi-Fi began after flashing, it is recommended to return the originally used firmware back.

Solution 6: Replace Wi-Fi module/motherboard

If the above methods are ineffective, then replacing the motherboard with a working module will solve the problem. In some tablets, the Wi-Fi module is presented as a separate board. Then you do not need to change the motherboard, just unsolder the old module and solder a new or used one, but in good condition.

Often it is not possible to find a suitable module. In this case, "implantation" helps USB WiFi module as shown in the images below. One end of the wire should be soldered to the USB contacts, the other to the contacts on motherboard. If there are no signs near the soldering points, you should first find a diagram.

Conclusion

When using the Internet, the chain of participants consists of three links - a provider, network equipment and a user device - a tablet. To quickly resolve connection problems, it is important to determine in which link the malfunction occurred. The article contains detailed troubleshooting steps if the tablet does not connect to wifi. Solutions are grouped into categories for sequential execution, as well as a better understanding for beginners and advanced users.

The tablet does not connect to WiFi not only when there are problems with the network. Perhaps the problem lies in the tablet itself.

Let's take a look at how to resolve the issue.

Android tablet users quite often encounter non-working WiFi. Almost all the causes of the problem you can solve on your own.

Wrong password entry

One of the most common mistakes the user is to blame for is entering the wrong password.

If you do not know why you cannot access the Internet via WiFi, when entering a password, click on the "show password" checkbox to make sure that all letters and numbers are entered correctly.

If you are entering the access code correctly, you should consider the following possible reasons breakdowns shown below.

No settings need to be made with the tablet itself, this can only aggravate the situation.

All actions will be carried out exclusively with the router.

Problems with the operation of the router can occur due to its incorrect configuration, when too many subscribers are simultaneously connected and using the device, power outages and other problems.

Unplug the router from the network for a few minutes and then plug it back in, this method can also solve the problem with the connection.

Checking the encryption algorithm used

If your tablet does not connect to the router, and the status bar says saved, the problem is different types encryption that use the tablet and router.

If a newer encryption mode is selected on the tablet than on the tablet, the user will not be able to authenticate, thus accessing the Internet will not be possible.

This problem is common on Samsung and Lenovo tablets.

Follow the instructions to set up identical encryption types and resolve the issue:

• Enter the router settings. To do this, you need to connect to it using your personal computer or laptop;
• Open a browser;
• Enter the router address in the address bar and press Enter (the IP address is indicated on the back of the router panel or in the instructions).
  If you did not find such data, then remember that the router, depending on the manufacturer and model, can only accept one of two local hosts: 192.168.1.1 or 192.168.0.1;

• To accurately view the local IP, go to the command line and enter the IPCONFIG command in it.
  Find the field called "default gateway" and in the right column look at its value - this is the local address of the router in home network. An example of working with the command line is shown in the figure below;

• Write the found address in the browser;
• Enter your browser admin username and password. You can view the login data in the instructions for the device (router);

• On the tab quick settings check the type of router encryption you are using. Set it to the same type as on your tablet. The type of encryption that the Android device uses is listed under the name WiFi in the connection window.
  An example of viewing the type of encryption that the router uses is shown in the figure below;

If you set all the settings correctly, device authentication will proceed normally, and you will find that the tablet sees the network and connects to it.

MAC filter

Incorrect filtering of so-called MAC addresses is another common cause of errors when connecting an Android device to a router.

Typically, the problem occurs on Asus tablets and Lenovo in the process of their interaction with inexpensive budget versions of routers.

To increase the level of connection security, you need to determine the MAC address - physical adress computer on the Internet.

If this address is not defined for any reason, the router closes access to the Internet.

This may be the reason that the tablet stopped connecting and an error occurred.

To correct your MAC address settings, follow the instructions:

• Go to your router settings. How to do this is described in detail in the previous instructions of the article;
• Go to the "Network" tab. The names of the tabs may differ depending on the model of the router you are using. In the "Network" tab, make sure that the MAC addresses of the device and computer are identical;

• Press the save key, reboot the router and the device;
• Connect to the router again. Everything should be stable.

Important! You can find out the physical address of the user tablet on the official website of the manufacturer or in the instructions for the device. Physically, an address is a unique identifier.

You can also disable filtering in the router settings. Do this if you couldn't find your device's personal ID.

You can turn off filtering in the "Network" tab in the main settings of the router.

As a rule, disabling filtering solves the problem.

To start working with the Internet, restart the tablet and router.

On the tablet, enter the access password again, the connection process after deleting the MAC address settings may take several minutes.

Channel setup

If even after disabling the filtering, you could not establish an Internet connection, check the channels.

Inconsistencies in the channels used can also cause problems when connecting to the Internet from the tablet.

Back out the window initial settings router. Find the line called "Chanel" and change its value.

Try to try all the values: select one of the channel modes, save the settings. Restart your tablet and router.

Try to connect again. Do this until you have tried all the available channel setting modes that are presented in the router control window.

Automatic mode allows the router to automatically determine the most appropriate channel for establishing communication with the subscriber device.

If the network still does not work, try hard resetting your tablet - that is, returning to the factory settings.

There might be a problem with software Android devices. You can reset the settings in the tablet settings menu.

Connection mode set incorrectly

If all previous ways settings did not help you solve the problem with the connection of the tablet and the router, you should try the last of possible ways fix the problem, which will most likely return your device to the ability to connect to the router.

Perhaps the tablet and router are operating different versions wireless connection.

The tablet may simply not see or not support the version of communication used by the router, so there is no connection to the Internet.

There are several options for connection modes: 802.11n, 802.11b, 802.11g. Go to the router settings and check the connection mode option you are using.

Change it to any other. Reboot all devices and try to connect again.

Thus, test the performance of all available channel versions.

It is necessary to perform all the actions proposed in the article one by one, since all problems are the result of each other.

All the instructions described in the article will help you solve the connection problem and improve the quality of your Internet connection.

What to do if Wi-Fi is connected but the Internet does not work on Android

What to do if the tablet does not connect to WiFi - Instructions with examples

Hello everyone, I haven't written anything for two whole days. And so today I will tell you why on tablet wifi connected but no internet. Due to the fact that many of the tablets used are based on the popular Android OS, I will talk specifically about solving problems with such devices.

The problem that lovers face tablet devices in the process of working with wireless internet, this is the display of the line "Obtaining an IP address". The operation of the gadget at this stage stops, and is not restored in the future. In fact, there are a couple of methods to solve the above problem, one of them should definitely help.

1. Change name WiFi networks to any other, including only English letters.
2. Reboot the router (this trivial method is often the most effective).
3. Change the type of data encryption (in the same place as the name wireless network, it is necessary to change the type of protection to another).

For the entered settings to be applied, modem needs to be rebooted.

Preparatory process

Today I have everything, I hope you now know why wifi is connected on the tablet and there is no Internet. I want to ask you something else, if something doesn’t work out for you, write about it in the comments. Also, I will not refuse if, as a token of gratitude, like this article. I wish you all only positive emotions and good health.

With Uv. Evgeny Kryzhanovsky

Every person in the world who has had even the smallest experience with a computer has heard such a phrase as " computer virus ". And from this phrase it becomes clear that nothing good can be expected from this.

Computer viruses exist from the initial stage of development computer technology and the first was created in 1981 by a schoolboy named Richard Skrenta. This virus was spread using floppy disks, which were popular at the time. And because of his ability to clone himself into other media, he was named Elk Cloner. But unlike the viruses of our time, it was relatively harmless and only displayed text in poetic form on the monitor. But many years have passed and viruses, one might say, have evolved and are able to multiply in operating system and even evolve, and also be in the incubation period, waiting for certain commands laid down by the programmer. Only it infects and harms the "health" of the PC.

There are viruses that can be removed third party programs, and there are some that will be deleted only when the system is reinstalled. To date, more than fifty thousand varieties of dangerous programs are known to mankind. In order not to bring to this, it is always worth keeping one anti-virus program active. No matter what it is, third-party or built-in, purchased or free, it will always warn you about infected software and advise you not to install it. It is also worth having a program on your PC to protect against viruses on the Internet, or an extension in the browser. So what is he like? Let's figure it out.
Computer virus is a small program that can clone itself and embed its clones into the system code of other programs, or even replace them, causing irreparable harm to personal data stored on a PC. The main function of viruses is to delete data from hard drive or their theft for the purpose of transmission over the Internet. Also, viruses constantly work in a hidden mode, constantly overloading the system, from which there may be a shortage random access memory, overheating of the processor and hard drive. Or even crash your computer. So think about it, if an initially well-functioning computer began to “slow down”, then you should think about having malware in the OS and it will not be superfluous, for prevention, to scan for viruses.
What is a virus and what it is "eaten" with, sorted out. Now I would like to know who needs to create parasitic programs and why.
There are several types of people who create virus software - these are:
1. Novice programmers, the main component are teenagers and the creation of viruses, one of the opportunities to assert themselves. These types of viruses are easy to create and do not pose much danger to the computer, but they are extremely rare.
2. Professional programmers, the purpose of creating malware for them is malicious intent, which consists in stealing personal data or permanently deleting it from the media.
A virus can get into a computer in different ways. It can be a floppy disk, a flash drive, a file downloaded from the Internet. Also, attackers can distribute them through messaging services, sending a link to a dubious site. Let's look at some types of viruses and the purpose of their presence in the system.
1. Trojan. It got its name because of the well-known myth of Achilles. This parasite hides in other programs and after installation starts collecting information from the PC, such as passwords, and sends it to its creator.
2. Worm. The essence of this virus is to slow down the computer by cluttering it. Basically, the worm enters the PC through messaging.
3. Encryptors. This malware encrypts all data, after which it offers to buy an access key, but the purpose of the program is not to enrich, but to destroy data, one of the most common methods.
4. Rootkit. Programs designed to penetrate into someone else's PC remotely and rip off traces of being in it.
5. Extortionists. They completely block access to the computer, demanding to transfer funds about their creator. But the probability that the computer will be unlocked is very small. It is better to find an antivirus specializing in this topic and figure it out.
6. Spies. By the name it is clear that the program was created for the purpose of tracking, remembering pages visited, correspondence in social networks. networks and other actions performed on computers.
To protect yourself from all this computer ailment will help competent behavior on the Internet, the presence antivirus program and most effective method, timely update of the operating system.
