Mobile devices do not connect to Wi-Fi. Android does not connect to WI-FI, what to do, how to fix it. Incorrect password entry, temporary failure

Internet and latest electronic technology are very closely woven into our lives. And sometimes problems with Internet access can ruin all our plans and interfere with our work or leisure. The phone not only helps you stay in touch, but also opens the door from anywhere to the World Wide Web, to the Internet. At the same time, no one is immune from sudden problems, then the question arises: why does the phone not connect to WiFi router? This information also applies to those users who do not know why the tablet does not connect to WiFi.

Let's consider typical reasons below. It must be said right away that the solution may lie in simple manipulations with phone. Therefore, apply all the methods described below, without thinking that this will not help in your situation.

What could be the reasons for WiFi not working on a phone or tablet?

First you need to restart your phone and turn it off/on Wi-Fi network on the phone. Then reboot your router(s). If there is still no network, then the problem is different. Another thing that might help is to remove the battery and connect it again, then restart the phone.

The causes of this problem may be the presence of incorrect network or router security settings, as well as the channel operating mode. What errors can we most often see on our device?

  • In the connection status we see: “Obtaining an IP address...”, or simply “Connecting...”. But the phone does not connect to the network. That is, you specify the network where you want to connect, but the phone cannot do this.
  • Authentication problem (authentication error), or simply the status "Authentication...". Usually in in this case The message “Disconnected” appears, and the phone is still not connected to Wi-Fi.
  • The message in the device is “Saved, WPA\WPA2 protected.”
  • The phone connects to the router via Wi-Fi, but the Internet does not work and sites do not open in the browser.

What solutions could there be to get your phone or tablet to connect to WiFi?

So, possible options solutions to your problem.

Removing WiFi connection

The first thing I could advise you is to delete the connection that is saved on your phone. To do this, select the network through which you accessed the Internet and click on “Delete” or “Delete this network.” Below in the screenshot you can see what it looks like:

After that, try connecting to this network again.

Reboot the router

Sometimes, if there is a problem connecting not only your phone, but also other devices, you just need to reboot the router. A small note: you don’t just need to unplug and plug in the socket after a second, but unplug the router’s power cable for 10 seconds and only then plug it in again.

You must wait for some time so that there is no power left in the router. Such a circuit is often needed with other devices that are powered by energy. By the way, you can use the button that is on the router itself using the same procedure described above.

Changing the channel in the router

If you haven’t changed any settings and the connection with your router has always been without problems, then you should try changing the Wireless channel. This happens very rarely, but there is a small percentage that this setting can help you.

Where can you change the channel for your Wi-Fi? To do this, you need to go to your router’s settings in the “Wireless” tab and change the channel (Channel), then save the settings, reboot the router and try to connect. If it doesn’t work the first time, repeat the same scheme with other channels.

Check the password you enter when connecting to WiFi

If your phone displays an “Authentication” error, then the problem may be wrong password or incorrectly configured security settings.

The first thing you need to do is check the correctness specified password. How to do this, since some users may not be prompted to enter a password? You need to delete your connection and re-enter your password by clicking on your network. Always be careful when entering your password. If you have forgotten your password, you can look it up in the router settings.

Here are articles that will help you with this procedure:

If it's not a password issue, then you need to check your security settings. To do this, set the security type to WPA2. The password must be more than 8 characters and you can try use only numbers.

Saved, WPA\WPA2 protection and changing the password in the router

One of the most common problems is when the phone displays the message “Saved, WPA\WPA2 protected” and at the same time the connection icon may show the presence of a connection, but there is still no Internet in the device.

If the options described above do not help, then you need to check the Wireless operating mode/speed in the router settings, since the phone may not always support the router operating mode. To do this, you need to set the network to automatic or mixed mode instead of b, g or n.

If you couldn't fix the problem and you are still faced with the dilemma of why your phone won't connect to WiFi, try changing the encryption/security type that I already mentioned:

  • WPA/WPA2
  • WPA-PSK

These are the settings on my router:

Enter a new password (key) of 8 characters or more. It is advisable to change the password, as you may have forgotten the password and are entering a non-existent one.

Next - the same scheme: save the settings, reboot the router, delete the connection on the phone and connect by entering New Password. It should be remembered that the new password will need to be specified in other devices that use this router. For example, if you have a laptop or computer at home, you need to reconnect to WiFi by entering the new password that you specified in the router.

Channel width

Change the Channel Width in the router settings. Usually there are several options: Auto, 20MHz and 40MHz. After the change, save and reboot the router.

If there are other options, try using them.

MAC and IP address filter

Make sure it's disabled MAC filter or IP addresses. If you have activated this function in your router and have not specified which MAC and IP addresses can connect to the routers, then the problem may be in this particular router setting.

Here are the most common reasons why a tablet or phone does not connect to WiFi. I hope one of my tips helps you.

By the way, if you have a problem with WiFi itself, then read the article “”:

Here is an example when a user could not connect to WiFi from an iPad:

A very common situation: a user tries to connect to Wi-Fi from his phone, but nothing works. After reading the information below, you will learn why this is happening and how to solve the problem.

Initial phone check

Manufacturers are actively working to improve the stability of mobile phones. operating systems, but periodically any program crashes. That is why it is recommended to start solving the problem by checking the functionality of the phone. For Android, iOS and Windows Phone (Windows Mobile) the recommendations in this case are identical. Follow the sequence below.

1. Restart your device and try connecting to Wi-Fi again.

2. Evaluate the number of connection signal strength indicators. If there are less than 3, try moving closer to the router or other source you are using wireless internet to improve connection quality.

3. Make sure Battery Saver mode is turned off. If necessary, connect the network adapter.

4. Turn off Bluetooth. Wireless connections may operate in the same range, which causes interference.

5. Turn off Airplane mode, if active.

6. Try to activate access to information about your location and connect to Wi-Fi - the legislation of some countries blocks connections via wireless networks when this option is inactive.

If the WiFi connection worked previously

If you have successfully used the currently problematic network in the past, remove this connection from your phone's memory. To do this, go to the list of networks, click on the problematic connection for a few seconds (until the context menu) and delete the connection.

If all else fails, try connecting from your phone to any other available connection. Failure in this case will most likely indicate a breakdown of the radio module - only service center employees will help correct the situation.

Check if the connection is working. To do this, try connecting to it using any other device that has Wi-Fi function. If the connection does not work, change the router settings.

Important note! The procedure for entering the router settings varies depending on the manufacturer and model of the equipment. In most cases, to gain access you need to enter address bar browser address 192.168.0.0 or 192.168.0.1. The standard login and password are admin. If this doesn’t work, check the manufacturer’s instructions for the information relevant to your router.

First, try simply rebooting the router - quite often they freeze, which is why access to the Internet is blocked.

The further procedure is as follows.

First, you must ensure that the security key you entered is correct. Try entering the password to connect to the selected access point again, but more carefully, with activated option“Display symbols” (show password).

If you don't remember the password, check it in the router settings.

As an example, the order of interaction with D-Link router. In your case, everything will be almost the same; minor changes may only affect the interface, menu item names and other little things.

Once on the router settings page, do the following:
click the “Advanced settings” button;
in the Wi-Fi window, open the “Security Settings” link;
in the line "Key PSK encryption» look at the password and make sure that this is the combination you enter when trying to connect to Wi-Fi from your phone.

Secondly, make sure your router settings are correct - you need to check if DHCP technology is enabled. If it is turned off, the phone will not be able to obtain an IP address, which is why the connection will not work.

On the router settings page, click “Advanced settings” again and in the “Network” window, find the “LAN” category.

Enable DHCP if the function is disabled by changing the “Mode” line to the “Allow” state.

Save the changes, restart the router and try connecting to Wi-Fi from your phone.

If this does not help, there are 3 options left:
call the provider’s support service and find out whether the Internet works at all and whether any changes have been made to the connection settings;
submit your phone for repair;
have your Internet router repaired/replaced.

If our instructions did not help solve the problem, then write in the comments and we will definitely look into your problem.

Hi all!

I analyzed a little of the comments that visitors leave on the site, checked the queries and realized that there is a very common problem with connecting to Wi-Fi, which I have not written about yet. But many comments were left on the site asking for help to solve this problem. I advised something there, but I don’t know if my advice helped you (rarely does anyone write about the results 🙁).

And yesterday, Roman (Thank you kind man :) I left a comment on the article in which I shared information about how he solved the problem “Saved, WPA\WPA2 protection”. This comment helped me understand the problem a little, and I decided to collect all the tips for solving this error in one article.

The essence of the problem

When connecting a phone or tablet (most likely on Android), To home network, or somewhere in a cafe, an inscription appears next to the name of the network “Saved, WPA\WPA2 protection”. And nothing else happens. If you click on this network and select To plug, then nothing will happen. You can see what this error looks like in the screenshot above.

I specifically provoked this problem on my Asus RT-N13U Wi-Fi router and tried to connect the phone HTC One V (Android 4.0) . So I got this message “Saved, WPA\WPA2 protection”. Moreover, everything worked out the first time. How? Yes, very simple. In my router settings “Mode wireless network” was in Auto mode, and I set it to n Only. I saved the settings, disconnected the phone from Wi-Fi, but it was no longer possible to connect :)

The main causes of the error “Saved, WPA\WPA2 protection”

Friends, I cannot say exactly everything and give advice that will be one hundred percent working, I hope you understand. All devices are different, everyone has different settings and many other nuances.

But I will try to collect the reasons known to me and ways to solve them, through which such a problem with connecting to a wireless network may arise.

If, when connecting to a wireless network, you see the message “Saved, WPA\WPA2 protected” on your phone (maybe a little different), then it’s worth checking these settings (I recommend checking in the same order):

To get started, simply reboot your router.

I have already noticed this problem several times: the Internet on the phone simply stops working, but there is a connection and the network is good. I turn Wi-Fi off and on on my phone, but it no longer connects to the network, it says “Saved, WPA2 protection.” Only rebooting the router helps.

  1. Set the correct region in the router settings
  2. Check whether the password for the Wi-Fi network is correct
  3. Check (change) the wireless network operating mode in the router settings
  4. Check (change) the encryption type and security type, change the password in the router settings
  5. Experiment with changing the channel on which your wireless network operates.
  6. Try changing the channel width.

And now in more detail on all points

Set the correct region in the router settings

Very often, this error occurs precisely because the Wi-Fi settings are set to the wrong region.

I'm on example Tp-Link I'll show you how to change the region. If you have a router from another company, then these settings are most likely changed on the same page where you set the name and other settings of the wireless network.

In Control Panel, go to the tab Wireless (Wireless mode) and opposite the point Region indicate the country you are in.

Save the settings by clicking the button Save(Save) .

Check your password and connect again

You may have simply entered your password incorrectly (though then most likely it will go permanent connection, round. But you need to check), and before getting into the router settings, I advise you to check this.

You may ask, how can I enter the password again, because the password request does not appear. You need to delete the connection. Just click on your network and select Delete.

Now, click on your network again and enter your Wi-Fi password. Just make sure it's correct. If you forgot, look at the password in the router settings, or on the connected computer (if there are any). Read more in the article.

Checking the wireless network operating mode

It seems to me that this main reason. Just your device (phone, tablet) may not support the operating mode in which the router operates.

The operating mode is those strange letters b/g/n, which you probably already noticed in the router settings. Try experimenting with changing modes. Don’t forget to reboot your router after each change and turn off/on Wi-Fi on your phone (tablet).

So I installed n Only instead of Auto and an error popped up. And if, for example, you already have n Only in your settings? Here are your problems.

Changing the encryption/security type, password

It may be that your device simply does not like the type of security or encryption that the router uses. Or you don't like the password.

I advise you to set the following values:

WPA/WPA2 - Personal (Recommended)

Version: WPA-PSK

Encryption: AES

PSK Password (key) – at least eight characters and numbers only.

We save, reboot the router, delete the connection on the phone, and connect by entering a new password.

Attention! After changing the password or other security settings, problems may arise with connecting other devices that were already connected to this network (computers, laptops, TVs).

Experimenting with the channel on which the Wi-Fi network operates

It's unlikely, of course, but it could be. I wrote about what a wireless network channel is, how to change it and why in the article -.

Try experimenting and see if it helps.

Channel width

There is such a point in Wi-Fi settings router, like Channel width. If you have, for example, TP-Link and the menu is in English, then it is called Channel Width.

There you can select several options: Auto, 20MHz and 40MHz - depending on the router. Try installing first Auto(or in Asus 20MHz/40MHz), if that doesn’t help, then separately.

Where can I change the channel width?

Go to the router settings ( address 192.168.1.1, or 192.168.0.1, enter login/password - look at the bottom of the router).

Asus

Go to the tab Wireless network and change the value opposite Channel width.

TP-Link

Tab Wireless – Wireless Settings, paragraph Channel Width.

Don't forget to save the settings and reboot the router.

Afterword

I seem to have written everything I wanted. I really hope that my advice will help you. You will get rid of this problem and connect your phone or tablet with a Wi-Fi router :)

Perhaps you know other solutions to this problem, share them in the comments - I will be grateful!

Best wishes!

The phone (tablet) does not connect to Wi-Fi, it says “Saved, WPA\WPA2 protected” updated: February 7, 2018 by: admin

There are many reasons why your phone won't connect to wifi. Cell phones are able to provide us with access to the Internet, no matter where we are.

However, sometimes it turns out that the phone has stopped connecting to a non-wifi network.

In most cases, the smartphone tells us what the problem is by displaying characteristic notifications on the screen.

Sometimes, when the connection indicator shows that the phone is connected to Wi-Fi, you still cannot access the Internet and pages do not load.

In this case, it makes sense to look for the “ ” notification in the network settings, which often appears in such cases.

In this case, you can try to solve the problem in two ways. Often this problem occurs due to the fault of the router.

Most likely, no matter what device you tried to connect to this network from at that moment, from a laptop or tablet, the result would be the same.

  • The simplest solution is to try turning the router off and on again. Let it cool down for about 10 minutes and try to connect again. It is likely that the problem will be fixed.
    Besides, this notice may appear if internet is not paid for at home. This problem is also completely solvable.
  • If the Internet is paid for, the wifi router has been turned off and on again, but you still cannot access the Internet, then the problem is most likely on the operator’s side, and therefore you should call customer support.
    Sometimes you will have to do the same if you cannot access the Internet only from your phone, although you can do this from other devices.

Important! Regardless of what connection problem and what method you solve, after taking action, you need to turn off the connection on the device. Then turn it on again to check its functionality.

Obtaining an IP address...

Other common problem occurs during the process of connecting the phone to the wifi router. The connection process stops when the phone attempts to obtain an IP address.

The notification “Obtaining an IP address...” may remain next to the network name for hours. Naturally, you cannot go online, since your phone is not connected to it.

  • The problem is not solved as easily as the previous one. However, the first step is the same - turn off and turn on the router again after 10 minutes. If you still cannot connect after this, proceed to the second step.
  • Not the best convenient way– registering a static IP address on the device. You actually specify the parameters of the network to which you connect at home.
    However, when using this method, problems will arise with accessing the Internet through other networks. In order to do this, you will have to erase the IP address and change its type.

Register static address can be done as follows:

  1. When you click on the title wifi networks, in the window that opens, an item called “Advanced settings” will appear, “ Extra options"or similar;
  2. Check the box next to this item;
  3. After that, in the “IP Options” or “IP Settings” section, change the type network protocol(DHCP) to static and register the IP.

Before you try to connect to the Internet through another network, change the protocol type again from static to automatic.

Authentication Error

A common reason why you cannot connect to the Internet.

This is a notification that your phone displays after attempting to connect to the network. wifi at home, actually means that the network has not recognized your device as suitable for wifi reception.

Most common reason why this is happening - the network password is incorrect. Check it carefully and try to go online again. If you are sure the password is correct, go to next step.

  • This is already familiar advice. Try turning your router off and on again after a few minutes. This is a universal recommendation that even operators give customer support subscribers.
  • More the hard way– try making changes to the router settings. To do this, you need to go to its settings page through a browser.

Select the following data in the router settings. Version WPA-PSK, encryption – AES. Enter the password.

On most routers these should only be numbers, no more than 8 pieces. Set the security mode to WPA\WPA 2 personal.

These options make connecting to wifi as easy as possible. However, such actions are necessary only when nothing else has helped.

And, in addition, there is reason to believe that there are compatibility problems, for example, with the type of encryption used by the router and phone.

The phone does not connect to WiFi - it’s just terrible, why is this happening, we know the answer, read all the reasons why the phone does not connect Wi-Fi here!

First, you should find the reason why your phone does not connect to Wi-Fi. Let's start with this.

Possible reasons

If your smartphone does not connect to your home wireless network, there may be several reasons for this:

  • incorrect;
  • Not correct settings on the router itself;
  • incorrect password;
  • blocking the device in the router list.

Important! Often the problem is not due to the fact that there is simply no connection. So, if you followed the instructions below and did not see the result, try checking other indicators!

Now let's look at each of the reasons and try to clarify why the phone does not connect to Wi-Fi router.

Setting up a mobile device

First of all, we check whether Wi-Fi is active, if the indicator wireless connection lights up on the device normal mode then we take the following actions:

First of all, delete the saved connection:

There are also very often situations when WiFi connects but pages do not load, quite large quantities case the matter lies in normal settings dates and times! Yes, yes, you just need to install the correct data on your smartphone or tablet!

In case if this algorithm did not help, then you need to go to the router settings.

Modem settings

If the router has already been configured, but your new phone or a friend’s device does not want to connect, it may be in the settings WiFi channel connections.

You need to change the channel from “Auto” to 7 (or any other until the devices start working, but most often it is channel 7).

To do this, through a laptop or computer connected via a patchcord, you need to go to the router settings:


Very often the connection problem occurs on Windows Phone smartphones and it is solved by changing the channel.

Forgot your router password

In this case, it can be viewed through a computer connected to this network. We have prepared a separate article for you on how to view your WiFi password.

If this option If you are not satisfied, then you can do it Hard Reset router and configure it again (the link to our article on this topic was above):


If, after checking all the settings and carrying out the necessary manipulations, the phone still does not connect to WiFi, then most likely the problem is in the WiFi module of the smartphone itself.

Resetting your smartphone

The last option here is to reset it to factory settings:

Attention! All personal data on the device will be deleted, so we strongly advise you to back up your files using any special application and synchronize contacts with gmail account, for their further restoration.

Now you know what to do if your smartphone does not connect to the Internet via Wi-Fi. Also on our website you will find solutions to other popular problems related to Wi-Fi and others. Using our instructions, you can quickly fix all the jambs and problems with your computers and phones.
