The phone finds Wi-Fi but does not connect. Phone won't connect to Wi-Fi


The article will tell you how to solve problems if your phone does not connect to Wi-Fi.

Navigation

Many users complain that they often fail to connect their phones to their home Wi-Fi. Of course, connecting your phone to Wi-Fi is necessary to essentially access free internet so as not to pay extra money for mobile Internet.

Therefore, in today's review, we will be discussing why phones sometimes do not connect to Wi-Fi and how to fix this problem.

Mobile phone sees Wi-Fi but cannot connect to the network

Mobile phone does not connect to Wi-Fi

It happens when we connect to Wi-Fi, we see it in our mobile phone, but nevertheless there is no access to the Internet at this time. Let's try to figure out this problem.

We can in in this case assume that the problem lies in the Wi-Fi device itself. That is, no matter what other device you connect to Wi-Fi (smartphone, tablet, phone, laptop), you still won’t have access to the Internet. If you wish, then make sure of this if you have another gadget or computer.

Now let's give the reasons similar problem and let's think about how to fix it:

  • Probably, many users notice that the connection to the Internet sometimes disappears if you connect to it via Wi-Fi. This problem can be solved very simply: turn off Wi-Fi and after 2-10 minutes turn it on again. In other words, reboot your device. Internet access returns in almost all cases. Also reconnect your phone to Wi-Fi.
  • Check, maybe you haven't paid for the Internet for the current month?
  • If you paid for the Internet and also rebooted your Wi-Fi, but still do not see any connection to the Internet, then most likely the fault lies with your provider. Perhaps they are undergoing maintenance work, an accident has occurred, or there are other specific problems. Call your provider and find out about this. By the way, it is possible that you can connect to the Internet via Wi-Fi, for example, from a computer, but you cannot do this from your phone. Call your provider anyway.

Requires obtaining an IP address

This problem also happens quite often. You connect your phone to Wi-Fi, but this cannot be done due to unsuccessful attempts to obtain the so-called IP address.

You can even see a corresponding notification on your phone screen, as shown in the screenshot below, but you can’t get the IP address. And without this you won’t be able to connect to the Internet:

Trying to get an IP address

  • Here it must be said right away that this problem a little more complicated than the previous one. But let's start with standard actions. Let's turn off Wi-Fi and turn it on again. If this does not help, then we will take other measures.
  • It will be a little difficult, but only a little. We register a static IP address in the device. That is, we seem to gain access to our network using some “password” that is suitable in this case. But keep in mind that later you will not be able to connect from your phone to another Wi-Fi, and you will have to erase the IP address that you entered earlier and change it from static to the one that was originally.

So, how to enter a static IP address on your phone:

  • We find the identified Wi-Fi in the phone and click on it
  • Next, an item like “ Additional settings "- put a checkmark in front of it.
  • Next in " IP parameters» set the settings as shown in the screenshot

IP Address Settings

Authentication Error

Another reason for lack of network access via Wi-Fi. If you see an error like this, it means that the Wi-Fi device did not recognize your phone. This may happen because you entered wrong password To log into your home Wi-Fi network:

Authentication Error

Accordingly, you need to double-check the correctness of the input given password. If, however, the password is entered correctly, then restart the Wi-Fi, as we have already learned to do according to the instructions above.

You can also configure your Wi-Fi as suggested in the screenshot (the only difference is that you enter your own PSK password, don’t forget about it):

Wi-Fi Settings

Saved, WPA2 protection

Saved, WPA2 protection

Here's another common reason why your phone can't connect to a Wi-Fi network. First, turn it off and on again Wi-Fi device, although we do not have any hopes for solving the problem in this case. We will need to delve into the settings of the router (remember, if you are a beginner, it is better not to refer to these instructions and consult with a specialist).

  • Check if you have entered the correct region
  • If the problem is related to the password, then follow the steps indicated in the previous instructions
  • You can also delete the old connection and establish a new one
  • Reboot your phone
  • Disable 3G network and check if this solves the problem

Video: Constantly obtaining an IP address - phones and tablets do not connect to WiFi

On modern phones ability to call mobile communications, this is just one of the functions. And for many this function is not the most popular. What do we mostly do on a smartphone? We watch the video, sit in in social networks, communicate in instant messengers, browse websites, play, etc., and for this we need an Internet connection. And when the phone does not connect to Wi-Fi, and the mobile Internet is very slow, expensive, or not available at all, then this is a tragedy. A phone without the Internet, like a computer, is not clear why you need it :)

Maybe I'm exaggerating a little, but that's basically true. All phones that run on Android (Samsung, Lenovo, Huawei, Xiaomi, Sony, Asus, Meizu and others) and iOS ( Apple iPhone) require an Internet connection. At least for setup, updating programs and systems, synchronization, etc. Now there are no problems with this. Almost every home has Wi-Fi router, which distributes the wireless network. Eat open wifi networks of neighbors, and full open networks from shopping centers, cafes, shops and other establishments. Even subways, trains, buses and planes have Wi-Fi. It's possible even without mobile internet always stay online.

But very often the phone simply does not want to connect to Wi-Fi. Such problems occur not only with open, public networks (where, as a rule, the problem is on the side of the network itself), but also with home Wi-Fi. I usually have problems connecting to one specific network. And sometimes the smartphone simply works with the router, then disconnects from it and does not connect again. Or it refuses to connect after replacing the router, some settings, installing programs, etc.

We will look at solutions for Android phones. If you have an iPhone, then see the article and.

Why is there no Wi-Fi connection on my phone and what should I do first?

First of all, it is very important to determine what specific problem is in your case:

  1. The phone doesn't connect at all Wi-Fi networks. It says “Saved”, constantly obtaining an IP address, authentication error, authentication error, incorrect password, error connecting to the Wi-Fi network, etc.
  2. The phone is connected to the Wi-Fi router, but the Internet does not work. Near the network itself there may be a message "The Internet may not be available" Exclamation point, or there will simply be no access to the Internet through the smartphone browser, or in programs. Error: "There is no Internet connection" or "Check your network connection." At the same time, the phone is connected to Wi-Fi.
  3. There is another option when can't see the phone the required Wi-Fi net. I talked about the solution to this problem in the article. We will not consider it today.

No matter what problem you have. Whether you are connecting to your home network or a public one, try these steps:

  • Disable and re-enable Wi-Fi on your smartphone. Better yet, reboot it.
  • Reboot your router if you have access to it. Just turn off the power for a few minutes and turn on again.
  • Check if other devices are connected and the Internet is working on them. This is especially true when a problem has arisen with connecting to your home Wi-Fi router.
  • If you cannot connect your phone to public wifi network in the metro, cafe, store, then most likely the reason is in the access point itself. Perhaps it's just glitched, temporarily doesn't work, or can't handle great amount clients. Just connect to a different network, or try connecting later.
  • Remember when the connection problems started. Perhaps you changed some settings on your router or phone, connected new devices, installed some programs, or something like that. This will help you find the cause and fix it quickly.

To make it easier for you to find and apply a solution, I will further divide the article into two parts: in the first part I will tell you what to do if your smartphone does not connect to Wi-Fi (appear various errors, writes saved, etc.), and in the second part - how to solve the problem when a mobile device is connected to a wireless network, but the Internet does not work.

The smartphone does not connect to home/public Wi-Fi (an error appears)

Let me clarify: in this section we will consider cases when, when trying to connect to some wireless network, our Android device does not connect at all (it happens that there is a connection but the Internet does not work, read about this in the second section of this article).

Main mistakes:

  • Error "Saved" (WPA2 or WPA).
  • It says "An authentication error occurred" or "Authentication failed".
  • It takes a long time to connect, or it constantly says “obtaining an IP address.”

Basic solutions on the phone

These solutions often help when a device was previously connected to that wireless network, but suddenly stopped connecting.

Don't forget to restart your mobile device and router first!

1 Remove the Wi-Fi network on your phone. Just go to your Wi-Fi settings, select the desired network, press it and hold it (or just click) and select "Delete network" or "Forget network".

Then select the network from the list again, enter the password and try to connect.

2 I recommend doing full reset network settings. On Android, this can be done in the "Reset" section. Item "Reset network settings". Depending on your phone manufacturer and Android version, these settings may vary slightly.

After which you will need to reconnect to the wireless network. Perhaps everything will connect and start working.

Error "Saved", "Authentication", "Authentication Error"

Such messages appear very often because we We enter the Wi-Fi password incorrectly.

Remove the network, or reset the network (I wrote about this above).

According to my observations, when connecting the phone it says saved, or an authentication error due to the fact that the phone “does not like” some Wi-Fi settings networks that are installed on the router. I will enter the network operating mode (b/g/n/ac), security type, channel and channel width, region, etc. There was even a case when the smartphone did not connect until it was changed Wi-Fi name network (SSID).

In this case, you can try changing some settings on your router. Of course, only if there are problems with your home network. We cannot change network settings in the same metro.

I also wrote about this problem in the article:.

I will write about solutions that can be applied on the router below in the article.

Obtaining an IP address... and the phone does not connect to Wi-Fi

We enter the password on the phone and the Wi-Fi connection freezes with the status “Obtaining an IP address...”. Common situation? Most often this happens for three reasons:

  1. Disabled on the phone automatic settings IP (possibly static addresses are set).
  2. The DHCP server is disabled or disabled on the router. But by default the DHCP server is always enabled and is very rarely disabled.
  3. Other restrictions from the access point. For example, your device is blocked in the router settings. Perhaps one of your relatives did this. Or the owner of the network to which you connected your phone.

Solutions:

On your smartphone, open the properties of a specific wireless network and make sure that “DHCP” is set in the “IP Settings” settings. If it's "Static", then change it to "DHCP".

Check if the DHCP server is running on the router. But most likely it works, this is unlikely to be the reason. Moreover, if other devices are connected without entering static IP addresses.

Well, don’t forget that you (your device) You could simply disable (block) in the settings of the router that broadcasts a wireless network to which you cannot connect your phone.

Setting up a router to solve a problem connecting an Android smartphone?

There, find the section with Wi-Fi settings network (Wireless) and try changing the following parameters:


Don't forget to save your settings and reboot your router every time! Remember which parameters you change and where.

The phone is connected to Wi-Fi but the Internet does not work

It seems to me that the problem with the lack of Internet connection while actively connected to Wi-Fi is much more common than the connection errors that I wrote about above.

From my experience I can say that this very often happens due to Android settings (time and date, for example), problems with DNS addresses and due to some programs (eg Freedom app). Sometimes (app store). It says there is no internet connection. But Wi-Fi is connected.

I don’t know how it is on other Android devices, but on Samsung phones.

What you need to find out:

  1. Does the Internet work on other devices when connected to this “problematic” network. If it works, then we are looking for the reason in the phone. If it doesn’t work, then the problem is on the side of the router (or provider) and needs to be solved. This is where my article may be useful to you.
  2. You can also try connecting your phone, which connects to Wi-Fi but on which the Internet does not work, to other networks. This way we can also understand on whose side the problem is.

Looks like we found out. If the router is at fault, then we look for and solve the problem on its side. If this is not a Wi-Fi network in the metro, or in another transport/institution (to the settings of which we do not have access). If the reason is our smartphone, then look at the solutions and links to other articles that I will provide below.

Time and date

Who would have thought that the phone might not connect to Wi-Fi due to incorrect date and time settings. But this happens!

Go to Android settings and check if the time and date are set correctly.

You can try disabling automatic settings and setting everything manually.

DNS problem

I can’t say exactly why this happens, but sometimes the Internet on the phone starts working only after .

To do this, you need to open the properties of the Wi-Fi network to which the smartphone is connected. (but no internet access) and in additional parameters register DNS:

This is what it looks like on a Samsung phone:

After this, the Internet should work. You can disable/enable Wi-Fi, or restart the phone.

Proxy server on Android

There are proxy server settings in the wireless network settings on your phone. So, if the proxy server is enabled, then the Internet connection most likely will not work. You need to open the properties of a specific Wi-Fi network and check/disable the proxy server.

Check that the settings are set to “Proxy” – “No” (or disabled).

Wi-Fi does not work due to programs

I have heard more than once about the Freedom program, which somehow disables access to the Internet via Wi-Fi networks. On purpose or by accident - it’s not clear. But in the same phone number home Wi-Fi network, or connected somewhere in the metro, but nothing loads. I am sure that there are many such programs.

If you encounter Freedom, then you need to go to the settings of this program, click on “Stop” there and only then delete the application. You can also install Dr.Web anti-virus on your phone and run a system scan.

Or perhaps you experienced these problems with the Internet immediately after installing some other application. Try to remember what you installed recently.

Reset the network, or completely reset the phone (Android)

If all else fails, then resetting the network parameters must be done in any case. I wrote above in this article how to do it. Cleaning network parameters will not affect your settings, programs, or personal data in any way. You just have to re-enter passwords for all wireless networks to which you have previously connected.

Well, if nothing helps at all, including resetting the network, then most likely you will have to do a complete reset of the phone.

Only if you are already convinced that the reason for the lack of Internet connection is your smartphone and no solutions have brought positive results.

If anything, I'm in touch in the comments. You can ask a question there, tell us about your problem, or add to the article useful information.

If you came to this page, then most likely your phone has stopped seeing the Wi-Fi network, or networks. This could be a home network, somewhere at a party, a public wireless network, etc. The problem is that the network we need does not appear in the list of available ones on the phone. He simply doesn’t find it, doesn’t see it, and accordingly it’s impossible to connect to such a network. There are often cases when a mobile device does not find a specific Wi-Fi network. Which, for example, a laptop sees and connects without problems. Or it may be that the phone does not find any networks, but other devices see them and work perfectly with them.

In this article I will try to collect all the most popular reasons and solutions that can help you solve this problem. As usual, it is first advisable to find out what the problem is: in the mobile phone or Wi-Fi router. If there is a problem with the Wi-Fi network at home, then we have a better chance of fixing everything, since we have access to the router itself. If this is someone else's network, then it is unlikely that anything will be done.

Basically, it doesn't make much difference on which device you have the problem. It is clear that this is most likely an Android or iOS phone. well, maybe more Windows Mobile. Since in the settings itself mobile device This problem can hardly be solved, it doesn’t matter what device you have. Same thing with the router.

I have already written separate articles on Android and iOS devices:

The phone does not see the Wi-Fi router: possible reasons

1 Disable/enable Wi-Fi, restart your phone and router. To get started, just go to your phone’s settings and turn off Wi-Fi. I think everyone knows how to do this.

Then turn it back on.

Reboot the phone:

  • On Android, just press and hold the power button, then select "Restart". Depending on the manufacturer and version of Android, the steps may vary slightly.
  • On an iPhone, you need to press and hold the Home button and the Power button. The phone will reboot.

Reboot the router. If you have access to it. It is enough to turn off the power for a minute and turn on the router again. You can perform several reboots in a row. You can read in more detail.

2 Let's determine what the reason is.

Check all three points:

  • If your phone doesn’t see any Wi-Fi networks, but they exist and other devices find them, then it’s clear that the problem is specifically with your smartphone. All I can advise is to reboot it and remove the case from it. If he is. If this doesn't help, you can try doing a full reset. If this does not help, you will have to take the device to a service center.
  • When a device does not find one network, the first thing you need to do is check whether other devices can see it. If they don’t see it, then most likely the problem is on the router’s side. First we reboot it. If this does not help, then see the article:.
  • If other devices find the Wi-Fi network, but your phone does not, but still sees other networks, then most likely the problem is in the router settings. As a rule, changing the wireless network channel and region helps. Below I will talk about this in more detail.
3 Change the router settings.

You need to go into the settings of your router, go to the section with Wi-Fi settings, and try to set static channel wireless network and other region. You can also set the channel width to 20 MHz. It's better to take turns.

On TP-Link routers it looks like this:

More details in the article: . You can experiment with the channel and region. For example, set the region to USA. If you had a static channel set in your settings, then set it to "Auto".

Other problems with detecting Wi-Fi networks

I also noticed that people often write that they can’t see the phone Laptop Wi-Fi. As I understand it, the problem occurs when distributing the Internet from a laptop or PC. In this case, I advise you to first make sure that the laptop distributes a wireless network. For example, view from other devices. You may have started the access point incorrectly. This is where the article will come in handy. Bring your phone closer to your computer.

The next case is when problems with Wi-Fi appear after the phone has been repaired. For example, after replacing the battery, screen, glass, case, etc. In such cases, I advise you to immediately take the phone to the workshop where it was repaired. Since the master most likely did not connect the antenna or the Wi-Fi module itself.

Well, there is no need to rule out hardware failure. Everything breaks down, and the module that is responsible for connecting to Wi-Fi is no exception.

As always, you can leave your question in the comments, or share useful information on this topic. I am always happy to answer your questions and grateful for additions to the article.

Every smartphone user has once encountered such a problem as endlessly obtaining an IP address - phone doesn't connect to WiFi and that's it! In this article I will tell you what to do if the phone does not see wifi, but instead constantly writes something like “authentication error”, “receiving IP” or “saved”. But I’ll immediately make a reservation that it is assumed that, firstly, the smartphone itself is in good condition. And secondly, the WiFi network on the router is also configured correctly and everything works on other phones or computers.

I will list the most popular reasons for the error:

  1. Invalid IP address
  2. Radio channel Wireless
  3. Encryption type
  4. China, motherfucker...

To immediately dismiss problems when the phone does not see wifi, which may be related to the router, try rebooting it and making sure that the DHCP server is enabled on it. That is, the router automatically distributes IP addresses to devices connecting to it.


In addition, you need to make sure that Network SSID not hidden in parameters wireless communication on the router - often to protect the connection from " prying eyes", activate this function, due to which the phone cannot see wifi network, although it actually works.

Reasons why your phone won't connect to WiFi

Now about each point in detail. The first thing I immediately do if my phone does not connect to WiFi is set a static IP address on it.

For Android and iPhone, this is done almost the same way - go to “Settings > WiFi”, see our active network connection and click on the arrow (on Android) or on the “i” icon on iPhone/iPad.


  • IP for the phone from the range of addresses specified in the router and available for use. If the router address is 192.168.1.1, then the phone can be assigned 192.168.1.45, for example.
  • Subnet mask - 255.255.255.0
  • The router is the IP of the router. On most models, the default address is either 192.168.1.1 or 192.168.0.1 - try them, if that doesn't work, contact your network administrator.
  • DNS is also the router’s IP, or you can use one of Google’s public addresses- 8.8.8.8 or 8.8.4.4.

On Android phones you will need to scroll to the bottom of the page to the “IP Settings” drop-down menu and change DHCP to “Custom”. Additional forms will open for entering the same parameters.

What to do if your phone doesn't see WiFi?

And a few more ways to solve the problem if we're talking about that the phone does not connect to WiFi.

Possible reason authentication errors may lie in the choice of radio channel for your wireless signal. I talked about it in detail in the article about, so I won’t explain for a long time how to set it up. And here it is worth noting that modern routers support up to 16 channels, while the older standard, which smartphones adhere to, had only 11 channels. If your router is set to automatic selection channel, then it can easily switch to channels 12 or 13 (exactly 13 channels are allowed for use over WiFi in Europe), and accordingly, the phone simply will not see it. So if you want a constant and stable connection on all devices, configure the channel on the router manually from 1 to 11.


If the phone is on Android, I want to disappoint you a little - the Android kernel does not always work correctly with the WPA2-TKIP encryption type, so if you have this type configured, then this may be the cause of problems with the Internet, and that the phone says “connection saved” , “getting ip” and other nonsense. This is especially true for cheap Chinese products.

The topic of China cannot be ignored regarding the routers themselves - often their products have non-standard operating modes - both in terms of channels, encryption and other indicators, so the modes of a Chinese router may not be fully understood by a “purebred” Android. The solution is to change the router to production more famous brand and a model of a higher class.

WiFi is wireless technology new generation. Just a little time, and this method of connecting to the Internet is used by millions of users around the world. Wi-Fi connection does possible connection compatible devices located at a distance of up to fifty meters from the access point. The data exchange rate is about 150 mb/s. However, that's not all. Thanks to latest achievements in this area, speeds can reach several gigabits.

Every modern laptop, tablet or phone has a Wi-Fi radio module. Thanks to this, there is a significant saving in the expensive traffic of mobile operators, and the radio module also provides access to multimedia content High Quality, and you don't need to download anything to your device. All you need to do is set up a Wi-Fi connection on your portable device, set a security password and then save it to open wide access to the Internet. However, sometimes not everything goes as smoothly as it seems.

Sometimes Wi-Fi doesn't connect. Why? There are a number of reasons for this, the main ones of which we will now discuss.

Why do problems arise?

Mostly, failures when connecting the device to a Wi-Fi network occur due to incorrect settings wireless router. In this case, the laptop or tablet does not recognize the Internet connection at all. If this happens at home, you need to sequentially perform a series of actions described below:

If a pop-up message appears when you connect your portable device to a Wi-Fi network “Saved, WPA-WPA2 protection”, this means that the encryption on the router is incorrectly configured or the password for Wi-Fi coverage. To fix everything, you need to do following instructions:

  • Check if the password is entered correctly by opening “Connection” and clicking “Change”. Next, you need to select the password display function and enter it again.
  • If the password is entered correctly, but there is still no access, it means that the router settings are problematic.

If the settings are incorrect, you must:


Bottom line

So now your laptop, tablet or smartphone should be able to connect to Wi-Fi. In this case, the initial connection between the device and the router will be broken, you need to connect again. Regarding encryption issues, in these cases you also need to proceed step by step:

  • You need to go to the “Settings” of the router, select the “Network Security” item - sub-item “WEP”, “WPA/WPA2”, and then enter a password that will help the router recognize the user. You will understand which item to choose from the error message, or you can experiment yourself.
  • Next, you need to save the settings using the appropriate function, and then reboot the router.

These are, perhaps, all the main actions that you can do at this stage. In other cases, it is better to contact specialists for more precise settings.
