LG phone does not connect to wifi. Security key mismatch

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, mother...

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 the network SSID is not hidden in the settings wireless communication on the router - often to protect the connection from " prying eyes", activate this function, due to which the phone does not see the 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”, we see our active connection to the network 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 it comes to the fact 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 channel selection mode, then it can easily switch to channels 12 or 13 (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.

If you came to this page, then most likely your phone has stopped seeing 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 some specific Wi-Fi net. 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 Android versions, 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 does not 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 full reset settings. 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. Changing the channel usually helps. wireless network and region. 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 usual, 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.

If your phone does not connect to Wi-Fi, this may indicate incorrect settings or problems with the router. Troubleshooting connection problems wireless point access must begin with checking the functionality of the devices. This instruction Suitable for iPhones, as well as Android smartphones from the following companies: Asus, Honor, Samsung, Beeline, Huawei, Meizu, LG, Motorola, HTC, Nokia, Fly, Sony, Lenovo, Xiaomi, Alcatel, ZTE, etc.

If it doesn't work WiFi connection on an Android smartphone, the following factors may contribute to this:

  • Lack of local wireless network or bad connection in room;
  • The security key was entered incorrectly;
  • The smartphone is not configured correctly;
  • System error in the operation of the Android platform (the driver has crashed);
  • Incorrect router settings;
  • Router freezes.

To troubleshoot connection problems global network Internet, most often a call to the provider’s technical support is enough. Often the reason lies in a malfunction of the company’s equipment, and it can be problematic to understand why Wi-Fi on the phone does not connect without two-way diagnostics.

First actions

In order to find out why your phone does not connect to Wi-Fi, you must follow these steps:

  1. Reboot the router itself (it is advisable to keep it unplugged for a couple of minutes).
  2. After restarting the phone, log in Wi-Fi settings and delete the previous access point.
  3. Start searching for the network again, being at the maximum close range to the signal source. After connecting to the network, you must enter the password again.

If Wi-Fi is not connected using this method, you will have to move on to more complex manipulations.

Enable and disable Airplane Mode

Very often, this method helps. Airplane mode turns everything off wireless interfaces on gadgets, regardless of their manufacturer. The method works equally well for both iOS and Android devices.

Another one of the most effective ways, most often helps in situations with gadgets from Samsung, HTC, Sony, Lenovo and others based on Google operating systems.

In this case, drivers and settings are completely unloaded from system memory, followed by loading correct parameters. In 90% of cases it helps solve the problem, but most likely this will be a temporary measure and it is worth observing the behavior smart phone. There is a possibility that Android was infected with viruses.

Checking the security key

It often happens that mobile phone does not connect to home Wi-Fi because the encryption key for the WEP, WPA or WPA2 standard is incorrectly designated. Therefore, you need to specify it again by checking the “Show access code” box in order to prevent errors.

How to find out the Wi-Fi router password through settings

If you can't remember your password, you can refer to the access point's security settings to find it:

  1. In the PC toolbar, open “Internet Access”, then right click mouse click on the network name.
  2. Select "Properties". In the window that appears, open the “Security” tab and check the box called “Display entered characters.”

After the security key is displayed, you need to enter it into your phone and connect to the network. It is better if the indicated characters are displayed on the smartphone in order to avoid entering incorrect data and wasting time again.

If the settings on your laptop (computer) are also lost, you need to find out the router password, because... every router has its own special IP address. In almost all models it is printed on a tag that is glued to the back. If you have saved the instructions, you can see the password for entering the settings in it.

In 90% of cases, the login and password to enter the router interface is admin.

Instructions

The algorithm of actions that will make it easy to find out the router password is very simple:

  1. Enter device settings using a laptop or desktop computer using power cord, which comes with the router.
  2. IN address bar enter the IP of any browser Wi-Fi router. Next, fill out the fields with access data from the router management page, which are almost always provided on the back of the router (usually set as admin/admin by default). The settings page will then be displayed.
  3. If information from reverse side no, let's start command line with the Start+R keys. In the window that opens, write CMD and press “Enter.”
  4. Specify the IPCONFIG command. Connection details will appear on the screen. We find the item “Main gateway”. The IP address that opens should be copied into a line in the browser. After that, enter your password and login and click “Login”.

It is worth noting that the settings of many routers are identical, the only difference is appearance and individual functions.

How to get an access code using LinkDir-615 as an example:

  1. At the bottom of the screen, click on “Advanced settings”.
  2. In the “Wi-Fi” menu we find “PSK encryption key”, where the required network password will be indicated.

Conclusion

If the above instructions do not help, you need to call hotline provider and clarify whether changes have been made to the connection settings. The lack of adjustments may indicate a malfunction of the router itself, so you will have to send it in for repairs or replace it with a new one.

    Good afternoon
    I came across this problem. My samsung smartphone Galaxy Advanced periodically refuses to connect to the wifi network, displaying the following message “security policy restricts the use of insecure wifi networks.” This happened for the first time abroad, and I decided that this problem arose precisely because my phone was somehow configured differently. At the same time, my friends had everything connected.
    When I got home I thought the problem was over, but recently I also couldn't connect to wifi. wherein home wifi It works perfectly, it almost always connects to other networks, but with enviable regularity it began to not connect when I leave Moscow.
    I've already looked through all the settings on my phone. I can’t figure out where else this security policy could be.
    help me please!

  • Khamzat

    Good evening! My Galaxy S3 automatically disconnects from the selected Wi-Fi network, although it still sees the network. Sometimes it reconnects on its own, but in most cases I have to turn Wi-Fi off and on again manually. I’ve had it for almost a year, it’s worked great all this time, but I’ve had this problem for two weeks now. I did a factory reset and that's it possible settings I did Wi-Fi, turned off sleep mode, etc. But the problem remains. Please advise something))

  • Khamzat

    Could this be due to the phone being rooted? I have one more “suspect”), this is an antivirus. However, the rooting and removal of the antivirus was done at the same time. I can’t guess exactly what could be causing this problem. Thank you in advance!

  • Anastasia

    Hello! I have a Samsung galaxy s3. The question is: at work there is wi-fi, to connect to which you need to enter a password (changes once a month) on a certain website (“login required”). Everything was ok, but from 10.09 to 10.10 I was not at work. Now I came and it connects to wi-fi, but it doesn’t offer to log in => I can’t enter the password => there is no internet when wi-fi is connected.
    Everything is ok with the router, because not a single person has had such a problem.
    I “forgot” the network, rebooted the phone, turned the phone off and on, everything is useless. At home I log in with the usual password and everything is ok, but I started turning off wi-fi when blocked (it reconnects every time)
    What's the matter?
