The phone does not detect Wi-Fi. Android does not see WiFi network

Why can't my Android phone see the WiFi network from my laptop? This question often worries users. It is worth noting that when distributing WiFi from a laptop, you get the same network as using a regular router. Therefore, the principle of its operation and configuration 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 in different ways. One of them is organizing a “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 doesn't Android see the 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 settings, 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 on 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 at the access point itself (in the router or laptop). So, let's look at both options in more detail.

Why Android may not see the WiFi network (video)

Setting up 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 all the necessary adjustments. To do this, connect to an access point on your laptop or desktop PC. Open your favorite browser and enter the router's IP in the address bar. How to recognize him. As a rule, there is a sticker on the device itself with all the data. But if it is not there, the necessary information can be found in the user manual. If there are no instructions, then we do the following.

Press two Windows keys + R at the same time. In the window that appears, write CMD and click “OK”. Thus, we launched the command line. Here you can view detailed information about the network to which your computer is connected. To do this, write ipconfig and press Enter. After this you will see the connection information. Here you need to find the line “Default Gateway”. This is the address we need to enter in the browser. As a rule, most routers have the following IP - 192.168.0.1 (but there are also 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 entered the desired address, press “Enter”. After this, 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 router parameters. The interface may vary depending on the model and brand of device. We will analyze further steps using the D-LinkDir-615 router as an example. But it is worth noting that all access points operate on the same principle, so their configuration is practically the same. The only difference is in the design of the menu and the names of some sections.

First of all, click on the “Advanced settings” button at the bottom of the screen. After this, additional sections will appear. We are interested in the item called “WiFi”. Here we enter the main settings.

First, check if the wireless connection is turned on. There should be a checkmark in the “Enable wireless connection” line. If it’s not there, then install it, save the settings 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 the value to "Auto" (automatic detection). A little lower 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 communication 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 checkmark here, uncheck it, save the settings, reboot the router and try connecting your smartphone or tablet to the network again. This completes the router setup.

Why Android won't connect to Wi-Fi: Video

Setting up a virtual access point on a laptop for network discovery

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

The fact is that simply creating a virtual access point is not enough. After this, 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). Right-click on it and select the required item from the menu that appears.

A menu will open in which you should enter the “Change advanced sharing settings” item. Here you just need to enable network discovery and allow file and printer sharing. In addition, at the very bottom of the menu you need to disable network access with password protection.

That's it, the setup is complete. Try connecting your Android to the network again. You must also remember 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 is worth noting that the WiFi adapter antenna in smartphones and tablets is even weaker than in a laptop. This means that in some cases Android may not see the network as a result of being too far away 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 available connections at all. The solution to this problem is simply move closer to the router. Or try moving the router closer to the center of the room and position it higher so that the signal can cover a larger area.

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

This article will talk about typical problems when connecting your phone to a wireless Wi-Fi network, the most common of which are Android stuck at “obtaining an IP address” or an authentication error when connecting. Less common, but it occurs when your Android phone or iPhone simply does not see the Wi-Fi network.

The step-by-step instructions will discuss the following problem options in order and what to do in each case.

• Authentication error (or phone says Saved WPA/WPA2)
• Endlessly obtaining an IP address on Android
• The phone does not see the Wi-Fi network

Wi-Fi authentication error on Android

If your Android phone or tablet reports “authentication error” when connecting to Wi-Fi, or writes “Authentication” for a while, and then still does not connect to the wireless network (when Android writes Saved WPA/WPA2 - this is usually the same situation) , then in most cases the problem is the Wi-Fi password, and the problem can occur even when you enter it correctly (but, of course, this is what you should check first, the article can help with this, you can also just look into router settings).

But it’s not always a matter of incorrect input: it happens that you are guaranteed to enter the password correctly, but an authentication error still occurs.

The first thing you should try here:

1. Delete the Wi-Fi network (forget it) in the phone settings, try connecting to it again by entering the password.
2. Reboot the router (unplug it and plug it back in).

If none of this helps, go to the router settings (any of the instructions for setting up a router on this site will help with this, they all start with how to go into the router settings), and then into the Wi-Fi network settings and try the following ( after each change, save the settings, delete the previously saved network on the phone and try to connect again):

If even these points do not help, make sure once again that in the Wi-Fi network security settings in the router settings, WPA/WPA2 (Personal) authentication is set, and not some other type (this option should be supported on any Android phone). It also sometimes helps to change the network operating mode from b/g/n or auto to 802.11 n only or 802.11 b/g.

Android constantly writes Obtaining an IP address and does not connect to Wi-Fi

The second most common problem with connecting a phone (specifically Android) is endless attempts to connect with the text “Obtaining an IP address.”

What could be causing the situation:

1. The DHCP server is disabled in the router settings.
2. Just an Android glitch.

If you don’t know exactly about the first point, then first just reboot the router, perhaps this will solve the problem. If this does not help, then the following steps:

• Check if DHCP is enabled on the router; if not, enable it.
• If it is enabled, but still “Obtaining an IP address,” then try setting a static IP address on the phone.

And now more about how to do both.

To enable the DHCP server, you will need to go to the router settings (any instructions for setting up D-Link, Asus, TP-link, Zyxel routers begin with a description of how to enter its settings) and make sure that the DHCP server is enabled (usually , there just needs to be a checkmark like this): on almost all router models this option is located in the LAN or LAN (local area network) section:

• On ASUS routers - LAN - DHCP server tab
• On TP-Link routers - Additional settings - DHCP settings
• On Zyxel Keenetic routers - In “Home Network” - Networking, enable “Server” for the DHCP option. Or, on Keenetic Lite, in Home Network - Segments, check that DHCP is enabled.
• On D-Link - in the “Network” or “LAN” section, the “DHCP Server” item or tab

The second option is to set a static IP address on Android, to do this:

Save the settings and try connecting to the Wi-Fi network from your phone again.

Android phone or iPhone does not see Wi-Fi network

If your phone does not see the desired Wi-Fi network, but sees other networks, then in most cases the problem is in the Wi-Fi channels used. The fact is that by default in the router settings in the wireless network parameters it is usually set to “Region: Russia” and channel: auto, which forces the router to select channels from 1 to 13. But: some devices do not support channels more than 10. (On this topic there is a separate instruction :)

Thus, the first thing you should try is to go into the router settings, go to the wireless network settings settings and change one of two things:

• Region - set to USA, supported by almost all devices, only 10 channels.
• Change the channel manually (set within 10).

After that, save the settings and check if your phone can see the network now. If this does not help solve the problem, then it makes sense to also try changing the channel width in the router settings, and for older phones, try also changing the network operating mode to 802.11 b/g.

Hello! Yes, I will write again about problems with Wi-Fi :). Someone needs to fight capricious wireless networks, which usually provide more inconvenience during setup than pleasure during use. Very, very many different problems arise, and most of them are difficult to even explain.

Today I will write about one of these problems. And I will give some recommendations that may help you solve it. But I can’t guarantee anything, I hope you understand.

What does the problem look like?

I think that after reading the title of this article, you can already understand what this article is about. I began to notice comments in which people wrote that their devices, be it a laptop, a computer with an adapter, a phone, a tablet, or a game console, did not see their home Wi-Fi network. It is simply not in the list of networks available for connection. At the same time, the device sees neighboring networks. But why? I thought for a long time, but could not come up with a logical explanation for this problem.

By the way, such nonsense can occur even after some work with Wi-Fi, that is, everything was working, you turned off the laptop (for example), and turned it on, but it no longer sees your network.

Here you need to act quickly and save your phone or other equipment from flying into a wall or window :)

Attention! This article is about when a device does not see a wireless network, but only one network, for example, while other neighboring networks are detected.

The device does not see Wi-Fi [possible solution]

Roman left the following comment on the site:

To be honest, I didn't know what to recommend. But then I thought again and realized that, as a rule, the most incomprehensible problems arise due to the channel on which the wireless network operates, or rather due to interference on the channel.

And I advised you to experiment with channels, as written in the article. Roman changed channel (unfortunately, he didn’t write which one he installed, but it doesn’t matter, you need to experiment) and everything worked for him. The laptop saw the network. A free channel can be determined using the InSSIDer program.

I don’t know if changing the channel really helped, or just rebooting the router 🙂 but the problem was solved. By the way, Reboot the router first if any problems arise. A simple reboot often helps.

There was also a comment where the game console stopped seeing the home wireless network. But I don’t know how it all ended.

You can also try experimenting with the mode of operation of the router, I wrote about this in the article.

Perhaps you have already encountered this problem and somehow solved it differently, or please leave your thoughts on this issue in the comments. And I will update the article and add useful material.

Bye everyone!

Description:
So, what to do if this unfortunate inscription appears? There are several reasons for this unpleasant situation and options for getting out of it.
Sometimes the phone does not connect to wifi and says wpa2 protection is saved. This can happen both when trying to connect to a public network or to a home one. This mostly applies to Android devices. This can be done equally by tablets and smartphones.
So, what to do if this unfortunate inscription appears? There are several reasons for this unpleasant situation and options for getting out of it.
Let's start by rebooting the router
1. Select the 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 wireless network password. Before changing your password, try connecting again. 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. Check the Wi-Fi network operating mode in the router settings. This may be the main cause of the problem. Your tablet or smartphone may simply not support the operating mode of this router. Check whether the device will work with other parameters, remembering to restart the router and disconnect and connect Wi-Fi on your smartphone or tablet after each change you make.
4. Check the security type and encryption type, change the router password in the settings. You need to set the following: WPA/WPA2 – Personal, WPA-PSK version, AES encryption. The PSK password must consist of eight digits. Then we save the new settings, reboot the router and disconnect and reconnect the phone. Don't forget to do the same on other devices running on the same wireless network.
5. Change the working Wi-Fi channel. Of course, this rarely happens, but it’s worth trying to experiment with the channels to be one hundred percent sure.
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 an Android phone does not connect to wifi, writes saved protected, it is worth noting that this could be both technical problems and a number of errors associated with forgetfulness or inattention 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 there is a problem with your Wi-Fi connection, you can successfully deal with it using these tips.

Sometimes a problem arises such as not being able to connect Android to a wireless point. How to solve this problem? Find out in this article!

And so you came to visit or are in a cafe, or perhaps you bought a new router and configured it to distribute the Internet via WI-FI, but your Android smartphone or tablet does not want to connect to the network or does not even see it! Don't worry, there is a way out!

Possible problems and solutions

1. If Android sees the network, but cannot connect to it, make sure that 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 router settings below)

3. If Android does not see the network, make sure that WI-FI network is functioning, reboot 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 a special application on the device from the Google Play store - Wi-Fi Fixer. After installation, restart Android and if the Wi-Fi Fixer application does not start, launch it yourself, then try connecting to the access point (you do not need to enter any settings into the application)

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

8. If you have custom firmware installed on your Android tablet or smartphone, then this may be the problem, reinstall it to the official one

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

12. Perhaps you have a Dlink router?

Setting up the router

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

Go to router settings

To do this, it is better to use a computer, as well as the FireFox or Internet Explorer browser. Let's open one of them. Next, you need to find out the entry address, which can be found by 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 located on the bottom of the router case.

Setting up WI-FI

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

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

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

4. Try changing the network security 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 give internal IP addresses on the network. If you disable the DHCP server, you may experience problems connecting to WI-FI and not only with Android devices!

6. Make sure that the MAC filter is not installed in the settings!

A MAC address is a personal (individual) serial number of a network device.

Depending on the router, there may be white lists of MAC addresses or black lists.

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

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

To find out the personal MAC address of Android you need to go to

Settings -> About smartphone (Tablet) -> General information

Try disabling the MAC address filter to resolve the connection problem.

If, after all these settings, Android does not connect to WI-FI, then it is worth updating the firmware either on your smartphone or tablet, as well as on the router; in rare cases, there is simply incompatibility, then nothing can be done!

The connection process is accompanied by the following comments from the operating system:

• Connection;
• Authentication;
• Saved, WPA protection

When unsuccessful authentication of the user-provided password occurs authentication error.

First of all it's worth re-enter your password manually and try to establish a connection with the access point. After making changes to the router settings, you must delete network from the memory of an Android device, which can “remember” the previous identifier. This is done quite simply:

• open on your smartphone Wi-Fi settings and find the desired network;
• then press on it with your finger and select the item that appears “ Forget»;

Even when choosing " Change» Authentication problems are not always solved, so a better solution would be reset all settings.

The problem of connecting old devices is solved regime change. It comes in three types:

• b– up to 11 Mbit/s;
• g– up to 54 Mbit/s;
• n– up to 600 Mbit/s.

Old devices does not work in 11bgn mode it is mixed, since they do not support the last one - n. The issue is being resolved installation 11bg mixed, after which reconnection is made without errors.

Infinitely obtaining an IP address

This problem may be due to the fact that the router disabled DHCP server parameter. Moreover, such a situation sometimes turns out to be simply consequence imperfect operating system.

The location of the parameter in the router interface may differ depending on the manufacturer. TP-Link, for example, takes it out a separate item main navigation menu.

The fastest way worth trying is reboot router. Then it will reset all its parameters to default values ​​and the DHCP server should turn on automatically.

If the connection is still unavailable, most likely the problem lies directly in the device on Android. To solve it you need:

After the above changes, the connection should work properly.

Problems with the router

Sometimes a smartphone can simply do not see the desired network. This is often due to settings channel - a certain subfrequency, which is a kind of road, a route between the device and the router.

The router can support up to 13 such “roads”, and some mobile devices only 10. Thus, if, for example, channel 11 is set in the router settings, the smartphone will simply does not see this “road”, and therefore ignores this access point.

Changing this parameter is not difficult. For example, in devices manufactured by TP-Link this is done as follows:

When there are a large number of access points in the environment, it is better to set the “ Auto" Then the router will independently select a free one from the available channels. If there are not many networks around, it is worth choosing a specific channel, which will allow speed up the process traffic exchange. To solve the problem with connecting an Android device, you need to select a channel within 10.

Recently I helped one of my blog readers solve a problem with a wireless network. The gist of it was that his phone did not connect to the WiFi router. Moreover, it was not just some cheap Chinese Lenovo, but an expensive (albeit also Chinese) fashion iPhone 6S. We spent a lot of time, tried many different options and, in the end, found a solution to the problem. Looking ahead, I will say that the “root of evil” was the incorrect configuration of the home router.
After all this, I decided to combine all our actions into one universal instruction - what to do if a tablet or phone does not connect to Wi-Fi, does not see the network, or sees it but cannot connect to it. Go.

1. The phone does not see the WiFi network

The most common reason is a mismatch between the region settings for the router and the tablet or phone. The fact is that almost all home routers and access points that are sold in Russia have the “Russia” region set by default, which uses 13 radio frequency channels. But phones, especially those brought from abroad, have a different region by default, which may have 10 or 11 channels. This is exactly the problem that most often occurs with iPhone smartphones and iPad tablets that came to us from the USA. The funny thing is that you can connect to the router, enjoy the benefits of a wireless network for some time, and one day discover that your phone does not see the router’s WiFi network. The solution is very simple. First, reboot your router. With a high degree of probability, after a restart it will occupy another radio channel and everything will work fine again. To avoid falling into the trap again, you can go to the router’s settings by entering its IP (or) in the address bar of the browser. After this, you need to go to the main WiFi settings:

In the “Region” field, try replacing “Russia” with the value “USA”:

You can do without changing the region. In the “Channel” list, replace “Auto” with the value 1 or 6:

As a rule, after this, iPhones no longer lose the wireless network and everything works like clockwork.

2. Can’t connect to Wi-Fi

In this case, usually all devices see the wireless network without problems, but when they try to connect to it, they are simply rejected. There are several options here:
- Endless connection
This usually happens when the communication standards used on the devices do not match. For example, the router is forced to use 802.11n, but the smartphone uses 802.11b or 802.11g. Or vice versa. Therefore, it is best to set the router to a mixed type - 802.11bgn.

- Infinite authorization
This very trouble can happen if the password on the router is changed, but the old one remains in the smartphone’s memory, which is why it cannot connect to the WiFi network. Try to find it in the list of available ones, click on it and select the “Delete this network” option in the menu that appears.

After that, select again from the list and try to connect.
It doesn’t help - then go to the security settings of the router and try setting the “WPA2-PSK” standard with “AES” encryption.

If this does not help, completely disable security and observe how the connection proceeds.

- The message “Obtaining an IP address” appears
This usually happens when the DHCP server is disabled in the router settings. We go to the web configurator, find the LAN or DHCP section and make sure that the DHCP server item is set to “Enable”.

Sometimes you may get stuck in obtaining an IP address due to the fact that a static IP address is registered in the Wi-Fi settings on the phone or tablet itself. To check this, open the “Settings” -> “WiFi” section and click on the connected network. In the menu that appears, select “Change”. A window like this will open in which you need to check the “Advanced” box. Next, make sure that the “IP address” field contains the value “DHCP”.

3. There is a connection, but no Internet

Start by checking whether other phones, tablets or laptops work through this Wi-Fi. Are they working? Then we go into our device, namely “Settings”>>>”Wi-Fi”>>>”Change network”:

We check whether work through a proxy server is enabled.
This option is also possible, although very, very rare, when an incorrect or non-working DNS server is assigned when connecting. It’s easy to check - in your phone, click on the desired network, select “Change” in the menu, check the “Advanced” box, “Manual” IP address and enter the full IP address from the router’s subnet, mask and gateway. But in the DNS servers field we enter the following values:

8.8.8.8 77.88.8.8

On an Android phone or tablet it looks like this:

These are public DNS from Google and Yandex. They are 100% working, which will completely eliminate this option.

If none of the above methods help, then try this. Take your device and check it on another wireless network - from a friend, acquaintance or comrade. If there the phone or tablet does not connect to the WiFi router either, then the problem is clearly in your device and it must be taken in for repair.

Quite often, Android users are faced with the fact that their smartphone or tablet does not connect to wifi, it says “saved”, but there is no connection. Alternatively, it should. Most often, this situation occurs due to malfunctions or errors. Before changing settings on your phone or tablet, you need to make sure that in your router:

• the correct region is set;
• the correct time is set - time desynchronization will not allow the device to create a timestamp;
• the wireless signal operating mode is configured;
• The encryption type is specified and supported by the device.

To make sure that you are entering the correct connection data, you can view the saved parameters in the router settings. To do this, from any connected device you need to go to the browser, enter 192.168.1.0 or 192.168.1.1 into the address bar (as a rule, it is registered on the router itself). In the menu that opens, find the SSID and PSK lines.

The reason why an Android smartphone does not connect to WiFi and says “Saved” may be a change in the encryption type, SSID or password.

What to do if, when connecting to WiFi, it says “Saved”, but there is no network
Regardless of whether the device is a tablet or a smartphone, the troubleshooting methods are the same:

• Check the router settings. What to pay attention to was described above.
• Reboot the router. Even if the router settings are correct, rebooting can help solve the problem: the connection will appear and the system will stop reporting the error.

• Re-create the connection on your phone or tablet. To do this, you will need to delete old data.

In general, the last point, when it does not connect to Wi-Fi with WPA2 protection, but writes saved, is quite simple:

• Delete. You need to go to Settings, click on the wireless connections tab (depending on the version, the name may differ). Having selected the desired connection, hold your finger on it and select delete in the menu that appears.
• Reboot the device's wireless module. After this, all available networks will be searched.
• Pass authentication. When a network is detected, you will need to re-enter the password. If the network is hidden, then you can add the SSID yourself. To do this, go to Settings - Wireless connections - Additional settings - Add new. In the window that appears, you need to write the name (SSID), security protocol and password.

These instructions should help if WiFi does not connect on your phone and it says “Saved” and “Without network access.”
