Why does the Android phone not see the WiFi network from the laptop? This question often worries users. It is worth noting that by distributing WiFi from a laptop, the same network is obtained as with a regular router. Therefore, the principle of its operation and settings is practically the same.

The only difference is that the router has more extensive and flexible parameters. In addition, you should know that you can organize an access point on a laptop different ways... One of them is the organization of the "Computer-to-computer" connection. In this case, your phone or tablet simply will not detect the network, since it is designed exclusively for computers.

Why does Android not see WiFi network

There can be many reasons for this. If you organized a network using a router, then first of all you will need to enter the parameters, since all settings are made exclusively in the router. If the network was created on a laptop, then you should go to the operating system settings. As you can see, you don't need to configure anything in the tablet or smartphone itself.

The fact is that the Android operating system is made in such a way that all the settings have already been entered and users simply have nothing to configure. Everything is extremely simple. Therefore, we will look for the cause of the error directly in the access point itself (in a router or laptop). So, let's take a closer look at both options.

Why Android may not see WiFi network (video)

Configuring the router

Very often, Android does not see the WiFi network due to incorrect router settings. So let's go into the router menu and make any necessary adjustments. To do this, connect to an access point on a laptop or desktop PC. Open your favorite browser and write the router's IP in the address bar. How to find it out. As a rule, on the device itself there is a sticker with all the data. But if she's not there, necessary information can be found in the user manual. If there is no instruction, then we do the following.

Press two keys Windows + R at the same time. In the window that appears, write CMD and click "OK". Thus, we ran command line... Here you can see detailed information about the network to which the computer is connected. To do this, write ipconfig and press Enter. After that, you will see the connection details. Here you need to find the line "Default gateway". It is this address that we need to register in the browser. As a rule, most routers have such an IP - 192.168.0.1 (but there are also such ones, 192.168.1.1) It all depends on the model.

How to easily find out the IP address of a WiFi router (video)

So, after we have written desired address press "Enter". After that, we need to enter a username and password. Here we write admin, admin, respectively. If you changed these values, then enter your data.

That's it, we got into the parameters of the router. The interface may differ depending on the model and brand of the device. We will analyze further steps using the example of the D-LinkDir-615 router. But it is worth noting that all access points work according to the same principle, therefore, their configuration is practically the same. The difference lies only in the design of the menu and the title of some sections.

First of all, you should click on the "Advanced settings" button at the bottom of the screen. After that, additional sections will appear. We are interested in the item called "WiFi". Here we go into the basic settings.

First, check if wireless connection... In the line "Include wireless connection"Must be ticked. If it is not there, then we set, save the parameters and check if Android finds our network.

If the problem is not solved, then we move on. Now you should check the channel. Try changing it. It is recommended to set it to “Auto” here. A little below you need to select the network mode. It is recommended to select 802.11 B \ G \ Nmixed from the list. This is a mixed mode in which devices that support different WiFi standards can connect to the network.

Now find the line "Hide access point". This feature hides your network. Because of this, devices simply cannot detect it. In this case, the connection to the router must be created manually. If there is a check mark here, then uncheck it, save the settings, restart the router and try to reconnect your smartphone or tablet to the network. This completes the router configuration.

Why Android Won't Connect to Wi-Fi: Video

Configuring a virtual hotspot on a laptop for network discovery

A very common question is why Android does not see the WiFi wireless network created on a laptop.

The point is that it is not enough just to create a virtual access point. After that, you should open access to it and enable detection.

This is done simply. First, we need to log into the network control center. To open the tool we need, find the network icon in the tray (in the lower right corner of the desktop). Click on it with the right mouse button and select the required item in the menu that appears.

A menu will open in which you should enter the item "Change Extra options general access ". Here you just need to turn on network discovery and enable file and printer sharing. In addition, at the very bottom of the menu, you must disable access to the network with password protection.

That's it, this completes the setup. Try connecting your Android to the network again. It should also be remembered that if you use a laptop as an access point, then the range of such a network is lower than that of a router. This is because laptops use less powerful antennas.

It should be noted that WiFi antenna the adapter in a smartphone and tablet is even weaker than in a laptop. This means that in some cases, Android may not see the networks as a result of too much distance from the signal source.

For example, on a laptop, the signal level is about 20% (2 sticks), and a smartphone in the same place does not see any available connections at all. The solution to this problem is just move closer to the router. Alternatively, try moving the router closer to the center of the room and positioning it higher so that the signal can cover a larger area.

Description:
And so, what to do if this unfortunate inscription appears? There are several reasons for such an unpleasant situation and options for getting out of it.
Sometimes the phone does not connect to wifi and writes wpa2 protection is saved. This can happen when trying to connect to a public network or to a home network. To a greater extent, this applies to Android devices. It can be done equally by tablets and smartphones.
And so, what to do if this ill-fated inscription appears? There are several reasons for such an unpleasant situation and options for getting out of it.
Let's start by rebooting the router
1. Choose correct region... To do this, go to the "Wireless" tab and in the "Region" line select the name of your country and save.
2. Check the password of the wireless network. Try connecting again before changing your password. To do this, click on your network and delete it. Then click on the network again, enter the password, make sure it is correct and try to connect.
3. We check the mode of operation of the Wi-Fi network in the settings of the router. This may be the main cause of the problem. Your tablet or smartphone may simply not support the operating mode of this router. Check if the device will work with other parameters, remembering to restart the router after each change and disconnect and connect Wi-Fi on your smartphone or tablet.
4. Check the security type and encryption type, change the router password in the settings. The following must be set: WPA / WPA2 - Personal, WPA-PSK version, AES encryption. PSK password must be eight digits long. Then we save the new settings, reboot the router and disconnect and reconnect the phone. Do not forget to do the same on other devices using the same wireless network.
5. Change the working Wi-Fi channel. Of course, this rarely happens, but you should try experimenting with the channels to be sure one hundred percent.
6. Change the width of the connection channel. To do this, you need to go to the router settings. In the “wireless network” tab, change the value opposite the “channel width” line, save the changes and reboot the device.
In conclusion, answering the question why the Android phone does not connect to wifi writes saved protected, it is worth noting this can be as technical problems, and a number of errors associated with forgetfulness or carelessness of users. There is an opinion that the reason lies in the Android OS itself, or rather in small flaws that cause various unpleasant moments. But if it happens that a problem with your Wi-Fi connection has arisen, you can successfully deal with it using these tips.

Sometimes there is such a problem as the inability to connect Android to a wireless WI-FI hotspot. How to solve this problem? Find out in this article!

And so you came to visit or are in a cafe, or maybe you bought a new router, set it up so that it distributes the Internet via WI-FI, and an Android smartphone or tablet does not want to connect to the network or even does not see it! Do not worry there is a way out!

Possible problems and solutions

1. If Android sees the network, but cannot connect to it - make sure you enter correct password!

2. If Android sees the network, but cannot connect to it - perhaps Android does not support protection type installed in the router, change the type of protection (read the router settings below)

3. If Android does not see the network - make sure WI - FI network is functioning, restart the router (on / off)

4. If Android does not see the network - perhaps Android, does not support WI-FI standard

5. If Android sees the network but cannot connect to it, restart Android and the router

6. If Android sees the network, but cannot connect to it, install on the device from the Google Play store special application- Wi-Fi Fixer. After installation, restart Android and if the Wi-Fi Fixer application does not start, start it yourself, then try to connect to the access point (you do not need to enter any settings in the application)

7. If Android sees the network, but cannot connect to it, although the password is entered correctly - perhaps Android does not support WI-FI standard on which the router is running (read the router settings below)

8. If you have custom firmware installed on your Android tablet or smartphone, then maybe it's in it, reinstall it on the official

9. The opposite advice to the previous one, if the official firmware is installed, then it is worth changing to a custom one (for example CyanogenMod), since it is possible that the WI-FI driver has already been updated there

12. Do you have a Dlink router?

Configuring the router

First of all, you need to get into the settings of the router.

Go to router settings

For this, it is better to use a computer, as well as a FireFox or Internet Explorer browser. We open one of them. Next, you need to find out the entry address, which you can find out knowing the network gateway.

This address must be entered into the address bar and go. Next, you will be asked to enter your username and password, which, as often happens, is on the bottom of the router case.

WI-FI setting

1. First of all, if Android does not connect, you should switch the WI-FI channel to auto

2.Change the standard of the WI-FI transmission mode to mix or only G

3. It is also worth checking the number of allowed connections of devices to the wireless network

4. Try to change the network protection method, change the encryption type from open to WPA

5. Another point worth paying attention to is the enabled DHCP server, which allows you to provide internal IP addresses on the network. If the DHCP server is disabled, then there may be problems with connecting to WI-FI and not only with Android devices!

6. Make sure that no MAC filter is installed in the settings!

Depending on the router, there may be whitelists from MAC addresses, or black ones.

Blacklisted- devices that are prohibited from entering the network, but other devices may.

White list- only those devices that are in this list and no other devices can connect.

To find out your personal Android MAC address, you need to go to

Try disabling the MAC filter to fix the connection problem.

A large number of subscribers using mobile communications are often asked questions about network problems, one of which is: "Why does the phone not see WiFi?" Now it is impossible to imagine that any of the mobile devices would remain without access to the Internet using this network. Naturally, even at home users have home network WiFi.

Why can't mobile devices see WiFi?

The WiFi network is now considered very convenient, affordable and mobile in almost all corners of the globe. She has many other advantages. For example, you can see pretty decent savings on the installation, deployment and expansion of the Internet. In addition, WiFi communication fully guarantees the compatibility of a number of equipment with different directions and many users. mobile communications at the same time in the same coverage area. But, unfortunately, not all mobile phone users have a chance to use this type of communication. And, of course, they ask themselves the question: "Why does the phone not see WiFi?"

Solving the problem of network visibility

Naturally, first you need to determine the reason why the phone stopped seeing home WiFi, that is, check if there is a connection at all. To do this, you can perform simple manipulations, for example, see if there is a connection to WiFi from other types of mobile devices. You also need to reboot the adapter.

Possible reasons why the phone does not see WiFi may be as follows: the user's mobile device must have the appropriate equipment - a special chip. Also, a large number of users, surprisingly, do not know how to independently configure this network.

To solve the problem of why the phone does not see WiFi, first you need to look at the settings of the router itself. Usually, the WiFi router automatically selects set point access (channel). A large number of mobile phones begin to experience minor problems when this very channel is higher than 12. You should change the channel itself to a value from 1 to 9, reboot the device and try to connect to the network. Naturally, do not forget about the settings of the mobile phone itself.

And if everything is configured correctly, you need to check the operation of the router and mobile device. You can also connect to a free access point somewhere for testing. And if the phone sees the network, then most likely the WiFi problem lies in the home router.

Network connection problem for Lenovo phones

It is very common for users of phones like Lenovo to have network connectivity issues as well. The problem arises that Lenovo phone does not see WiFi. The device itself provides the ability to work on channels 1 through 11. Often the router is tuned to a channel above 12, it turns out that there is an incompatibility between the mobile device and the router. If changing the channel helps for other mobile devices, then Lenovo needs to take other actions.

First, you need to find the build.prop file on your phone and replace the line ro.wifi.channels with ro.wifi.channels = 14. Such manipulation can be performed directly directly on the computer in any text editor by transferring the original file via USB. After that, you need to restart both the phone and the router. After all these actions, the mobile device should see the network.

WiFi programs for phone

In order to use all the capabilities of their mobile phone when connected to the network, they use numerous software... Now provided big choice WiFi programs for your phone. Such applications are used in order to make an access point to a WiFi network out of a mobile device. The main thing is to find good and inexpensive traffic. mobile internet, because, in principle, the mobile device will turn into a gateway between 3G and Wi-Fi network... And this will allow the device to connect to the World Wide Web. Programs are divided by the type of mobile phone platform, the most popular are Android, iOS, Windows Phone.

Android WiFi Apps: WiFi Tether and WiFi HotSpo

Currently, all multifunctional telephones used to access the network, social services or chat on the Internet are practically unnecessary if the phone stops seeing WiFi. When solving this problem, many realized that WiFi Tether for Root Users is considered a very easy-to-use program for the phone. The only thing that it is not so popular with users is that it requires rights Root access but it pays off with easily accessible features and usability. By default, this program sets a WiFi hotspot in open mode, connected without a password. Therefore, before using this program, respectively, you need to select an encryption protocol and specify a key for connecting the network.

Another WiFi app for your phone is WiFi HotSpo. It is also easy to use, but it has much fewer functions than WiFi Tether, but when using this particular program mobile phone no need to "rut" in advance. And what's so attractive about this app is that it has features like USB Tethering. It allows you to use the phone as a wired modem when connected via USB to a computer.

IOS based WiFi programs

Unlike programs for the Android platform, such utilities for IOS are not so common. But still there is good program WiFi for an iOS phone and that's MyWi. This application allows you to make a modem from a mobile device. But to make this possible, Apple devices you must first "unlock". The application has a very good monitoring capability. And if suddenly a connection is not established, or it works with interference, MyWi has the ability to select another channel. Its only drawback is that it is paid.

Program for Windows Phone

In one of the first versions of phones based on the operating room Windows systems Phone, it was impossible to use tethering. But in subsequent models mobile devices this option has been built into the system itself. It can be set to lock depending on which specific model phone is in use. The maximum connection to a network access point with active tethering is no more than five other mobile devices.

The problem of connecting mobile devices to the network and its solution

It is widely believed that WiFi network will soon replace one of the available links- mobile. But this raises one problem. There is still the impossibility of roaming on a global scale. After all, this network on this moment has a small radius of its action. And problems arise in the form of the phone not connecting to WiFi.

Nowadays, this network is already quite widespread everywhere. Developers such as Samsung, Zyxel, Hitachi were among the first to produce phones with network support. Also, some time later, other manufacturers began to develop such phones.

Today, the communication standard is probably the most inexpensive, and many providers provide these services free of charge. But it is not always possible to take advantage of the wireless network, and sometimes the question arises of what to do if the phone does not connect to WiFi.

It so happens that a mobile device sees the network itself, but does not want to connect to it. This is especially the case when the phone does not see the home WiFi. If in public places where the network is provided, such problems did not arise before, often the solution lies not in the phone itself, but in the home router, in its settings.

When solving such a problem, it is not necessary to turn to professionals, you can fix everything yourself. To do this, go to the device settings and change them. This can be done using any internet browser. Directly in you need to dial the IP of the router. These designations are 192.168.1.0 and 192.168.1.1. Next, you need to find the DHCP section and check the Enabled section, in other sections - Default Gateway and Primary DNS - you need to enter the IP of the router.

Thus, if all actions are performed correctly, then the question of whether should be resolved. This method helps to protect the exchange of data, that is, it makes it possible to set a password for a network connection. Only those users who are allowed to connect to it.

Nowadays, more and more often they use not a computer or laptop to access the Internet, but mobile gadgets such as a tablet or smartphone. And there is an explanation for this - most of the Internet is used to visit sites, versions of which are designed specifically for small screens ( social networks VKontakte, facebook, classmates, instagram), and you can't put a laptop in your pocket. It's good when a smartphone goes online via a 3G or GPRS connection, then it does not need additional equipment, but if through a wired provider (for example, ADSL or local area network with general access to the Internet), then the mobile phone must first connect to the router, and sometimes the router does not see the phone or another error is issued, the solutions of which will be discussed later.

By the way, mobile devices have several modes of access to the Internet, some of which are for distributing it to other connected devices (access point mode).

Smartphone hotspot mode

There is also a 3G modem mode, in which the smartphone is connected to the computer using USB cable, and thus the computer gains access to the network via a 3G connection.

But this article will consider the mode of connecting a smartphone to wireless wifi router, and in rare cases related problems.

Connecting a phone to a router

In order to successfully combine into computer network phone with a router, first of all you need to make sure that the router is turned on, the Wi-Fi module is active, and the WPS function is turned on (if available).

Found Wi-Fi networks

If the network is password protected, a window will open in which you must enter that password.

The password is entered only once, the phone remembers it and does not require entering it on subsequent connections.

If there are no errors, the "Connected" status will appear under the network name. That's it, the phone is connected to the wireless network of the router.

If the connection fails

But everything is not always so easy and simple, and for a number of reasons it is impossible to connect to the network.

Let's consider the most common cases:

1. “Hide SSID” is checked in the router settings.

Hide Wi-Fi network

If a ban is set, then the router does not broadcast the network name, and to connect to it, you need to manually register the network name in the smartphone;

2. Standards do not match. For example, a router operates in the IEEE 802.11g 2.4 GHz standard, and a smartphone operates in the IEEE 802.11n 5 GHz standard. In this case, they will not be able to work in pairs, the standards must either coincide or be compatible;

3. In the settings of the router, there may be a limitation on the connection of the number of subscribers, and your smartphone simply turns out to be superfluous.

Limiting the number of subscribers

4. And, as practice shows, a fairly common reason is simply a freeze of the router. Turn it off and on again, it might help, but it won't get any worse. In this case, try updating the router firmware to a more stable one.

Third party software

We looked at how to connect a phone to a router without help third-party programs, only by the phone's own operating system. But there are programs aimed at helping this issue... Let's give an example of one of these.

Appearance of the program

The program is called WeFi, you can download it on the official website of the program for free: http://www.wefi.com

I am very pleased with the multiplatform nature of the program. We choose operating system our smartphone and download the program to the computer, and then to the phone.

Operating system selection

For example, choose Android version... After installation on the smartphone, we launch the application and see the initial window.

The initial window of the program

A big plus of this program is its funny animation. The little man at the bottom of the screen is frankly happy when it turns out to connect to a Wi-Fi network without any problems.

But, nevertheless, the purpose of the program is somewhat different, namely, to facilitate connection, and WeFi does an excellent job with this task.

Program connection

One of the main features of the program - automatic connection to the network with the most the highest level signal. Of course, it can be configured to a specific network, but still the program is designed specifically for automation. The only thing is that you will have to enter the network password once, but you can't do without it.

Also very useful function as the continuation of Wi-Fi activity after the smartphone enters sleep mode.

Program setting

The only small disadvantage of the program is the absence of a blacklist, in some cases it may be needed (for example, in public places with paid, but not blocked access).

The full operation of the program can be seen in the video review:

Unlike a wired network, a Wi-Fi connection requires additional authentication, since the connection to the network within the range of the signal emitted by the router is public. Here, electronics are responsible for the Internet connection and there can be many reasons for the phone not seeing wifi at home: from provider problems to router malfunction. However, such a problem is extremely common, and the most "popular" reasons why the phone does not connect to home wifi, we will consider in this article.

Why the phone does not connect to wifi: we establish the correct "diagnosis"

So, if the phone does not catch Wi-Fi from the router, it is worth checking:

• 1. Is the router "frozen".

Indeed, some of the reasons that the phone does not see Wi-Fi can be safely called mystical. After all, this is what all unexplained phenomena are called? In fact, all routers, without exception, periodically refuse to perform the tasks assigned to them, and even the manufacturers of this equipment will not answer why this is happening.

So, if the phone stopped catching wifi after fruitful work with a wireless connection, the first thing to do is to reboot the router. To do this, just turn off the device using the ON / OFF button on the device (or pull out the power plug from the POWER jack), wait 30 seconds and reconnect the router to the mains.

Thus, if the phone does not see the wifi router due to its "freezing", the problem will be eliminated.

• 2. Correctness of phone authentication in the wireless network

If an authentication error occurs and the phone does not connect to WiFi, you first need to reboot your mobile device.

• 3. Is the number of devices in the home network exceeded?

To find out why the phone does not see wifi at home, and see how many devices are allowed to use your Wi-Fi.

You may have turned on your laptop, tablet, phones, etc. and your router only supports 16 wireless connections to your home network.

Or, you bet too much, and the student from the next doorway decided to show his friends that he is a cool hacker. The young cracker found the password and gave it to his friends.

Unauthorized connections can be “banned” through the router's web interface, after which be sure to change the password for accessing WiFi to a complex and unique one.

Do not forget to delete all connections on your mobile communicators after changing the key, and connect to the network with a new password.

• 4. Is the SSID repeating?

This is rare, but it happens. Some people either set a standard network identifier, or simplify the unique name to a simple one, for example, "dlink", "tplink", etc. home wifi an authentication error occurs.

Turn off your router and see if its name is in the list of available WiFi networks your phone? If a network with this name already exists, then change the SSID to a unique one, save the settings and reboot the router.

• 5. Whether the router or mobile phone is broken.

With regard to the router, you can try to reset the settings to the factory settings using the RESET button

and re-configure the device via the web interface in accordance with.

After such an "operation", all passwords will be changed to the factory ones, including the authentication data.

If, after a complete reconfiguration of the router, the phone still does not connect to the Internet via wifi, you should contact service center or a warranty workshop.
