When connecting to wifi it says identification problem. WiFi Authentication Error

All tips

An authentication error occurs when connecting to a WiFi network - this is a very common problem. That is why it is so important to understand why it appears and how to eliminate it. But before moving on to network settings and troubleshooting, you should understand what authentication is. This will help you understand why it appears this error and how to quickly and permanently eliminate it.

What is authentication

This is a wireless network security system that prevents outsiders from connecting to your group. Today, there are several types of authentication. You can select the most suitable option in the settings of the router or access point that is used to create home network. As a rule, nowadays the encryption type (authentication) used is WPA-PSKWPA2-PSK2 mixed.

This is the most secure type of data encryption and is very difficult to crack or bypass. However, it can also be divided into two types. For example, at home, an option with one key phrase for all subscribers is used. The user himself sets the key, which is subsequently required to connect to the network.

The second type of encryption is used in organizations that require an increased level of security. In this case, each trusted subscriber is assigned a unique passphrase. That is, you will be able to enter the group only from your computer and only after entering a unique key. In the vast majority of cases, an authentication error when connecting to a WiFi network occurs precisely when the encryption types and the entered passphrase do not match.

Why does the authentication error appear and how to fix it

As mentioned above, if when connecting to a WiFi network the system writes “Authentication error”, then first of all you should check the correct spelling key phrase, and whether it is enabled Caps Lock. , then you can check it in the router settings. But to do this you will have to connect to it using a cable.

Let's look at how to find out the password using the D-LinkDir-615 router as an example. After connecting to the device, open your favorite browser and address bar register the IP of the router. You can find it in the instructions or on the body of the device itself (carefully inspect it from all sides).

You can also find out the router's IP using command line. Press the Windows key combination + R, type CMD and press Enter. In the window that appears, write the ipconfig command. Find the line “Main gateway” - this is the address we need.

Write it in the address bar of your browser and press “Enter”. Next, the system will ask you to enter your username and password. We write admin, admin respectively.

Now at the bottom of the screen, find and click the “Advanced Settings” button. Several will appear additional windows. We are interested in the section called “WiFi”. You need to find security settings in it. This is where you can select the type of authentication (encryption) and change the password.

Sometimes an authentication problem when connecting a computer to WiFi appears even if the key is entered correctly. This may mean that the router has crashed or is simply frozen. This can be resolved by simply rebooting the device. This can be done in settings or simple shutdown food for 7-10 minutes.

You should also check the channel on which the router is operating. For this we return to start menu. In the WiFi section, click “Basic settings” and find the “Channel” line. It is recommended to set the value to “Automatic”.

There are also cases when such an error does not appear due to problems in the router or due to an incorrectly entered key. In this case, you should check the settings in the operating system.

OS check when authentication fails

To connect to wireless network The computer uses a Wi-Fi adapter. It is because of its incorrect operation that problems with WiFi network authentication may occur. First of all, you should check the presence and correct operation of drivers. This is done in the device manager, which can be launched as follows. Find the “My Computer” shortcut and click on it right click mice.

Select “Properties” and open “Device Manager”. You can also simultaneously press two keys – Windows + R, in the window that appears, write mmc devmgmt.msc and press “Enter”. In the window that appears, we are interested in “Network adapters”. Open the thread and see if yours is on the list WiFi module. As a rule, the title has Wireless Network Adapter If the device is marked exclamation mark, then the drivers are not working correctly.

Having installed Wi-Fi at home router, you get the opportunity to use high-speed Internet on your mobile gadgets. However, sometimes situations arise when the device does not connect to networks, does not see them, or issues various errors. The most common problem is the WiFi authentication error. The correct solution to this problem looks quite simple if you know what actions need to be taken. Let's look at what an authentication error is when connecting to WiFi on Android and what needs to be done to fix it.

First of all, you need to understand what is an authentication error? In accessible words - this is protection, which consists of double-checking the entered security password and the method of data encryption during the connection. These parameters undergo mandatory verification when connecting, since not only trusted users, but also attackers can connect via WiFi.

There are only two main reasons why Android does not connect to WiFi:

Different ways to encrypt network data. For example, when connecting, it says wpa2 protection is saved, but the Internet does not work, which means a conflict between the protocols of the router and the mobile device.
The password for connecting to the network was entered incorrectly.

In addition, Wi-Fi on Android may not work due to technical faults router, or the mobile gadget. If the matter is unstable work router, which, for example, can occur when loading large volumes data, you need to reboot it. In some cases, if the Internet does not work on Android, resetting the router settings may help by pressing the power button.

Solving the problem with connecting your phone to Wi-Fi

What should I do if Wi-Fi on my phone or tablet does not work, giving the error in question every time I connect? This paragraph covers two steps, by following which you will learn how to turn on the Internet on your mobile gadget.

Step One: Password Verification

When Android won't turn on wi-fi internet, the first step is to double-check the accuracy of the password. To do this you need to go to Wifi settings on your mobile phone, turn on the appropriate adapter and wait until the required network is displayed. Next, you need to press and hold it until a dialog box with parameters appears. It will contain the item “Forget network”, which you need to select. This will delete all Wi-Fi data on the phone for this network, including the set password.

Now you need to restart the search for available nearby wireless networks (by updating the list or switching the adapter) and connect to your router. It is recommended to check the box next to “show password” to be able to double-check the correctness of the characters, language layout and letter register. If it is written correctly, but authentication continues to give an error, then you need to log into the router’s website, where you can double-check the settings.

Step Two: Configuring the Encryption Type

Another reason why the Internet from the router stopped working could be a failure or incorrect installation encryption type. Before entering the router settings and fixing the error, you need to connect to it using any computer device.

By opening an Internet browser, in the line for entering the URL address, you need to enter the IP address, which is indicated in the instructions on how to connect the router. You can also view it by going to the control panel/network connections, or by opening the tab located at the bottom of the screen, next to language bar and for hours.
By clicking on the button, a window will open where you can see the active Wi-Fi.
To view the required IP address, just click on the tab with wireless connection located in the “Connection type” column.
In it you need to find the line “information” and “default gateway IPv4” located in the middle part of the list.
After this, you need to make a secure type of encryption for data transmitted over the network that is supported by your Android device. To do this, enter the previously found IP address in URL string browser and get to the login page. If you have not previously changed the login and password, you must write “admin” in both fields to enter them.

On the site you can find and set new privacy settings so that no one has access to your router settings. The further course of action is the same for most routers, however, the design of the menu interface and the name of the main tabs may vary depending on the model.

To fix the error you need:

Find the tab where you can change advanced connection settings. It is located at the very bottom of the list, and when you open it, several additional items. Among them we find “wireless networks”, which we will configure.
In the submenu, click on the item with connection security settings, where we will be interested in the line containing the basic parameters of network authentication.
It is recommended to add several different types encryption, as shown in the figure below and are supported by most popular mobile devices.

All that remains is to confirm your choice by clicking the “apply” button and reboot the switched on router. You can try connecting to Wi-Fi networks again using your smartphone, and if everything is done correctly, the error will be eliminated. We recommend watching a training video on how to set up WiFi on Android.

Video “Wi-Fi authentication problem in Android”

In this video you will see how to solve the problem Wi-Fi authentication in Android

Possibilities modern phones go far beyond voice communication. With no less success, they can be used to store and edit files and, of course, to connect to global network. Because the mobile standards most often limited by providers, to connect to the Internet, owners of gadgets on Android based and iOS are most often used Wi-Fi technology. But the mere presence of a Wi-Fi module in a mobile device does not guarantee a connection to the network.

It happens that the phone does not connect to Wi-Fi, displaying errors or notifying the user that the connection is impossible. Most often this occurs due to a failure or incorrect settings the device itself, but can lead to the same results incorrect configuration router modification system files, installation of custom firmware, non-compliance with communication standards, virus infection and, in rare cases, failure Wi-Fi module. So, let's try to look in more detail at why the phone doesn't connect to Wi-Fi and how it can be fixed.

Incorrect password entry, temporary failure

This error usually occurs when the Wi-Fi network cannot recognize the device connected to it. The reason is most often trivial - the user makes a mistake when entering the password and, as a result, receives a corresponding message.

Check that the password you entered is correct and try to connect again. Also pay attention to the name of the network. The Wi-Fi module on your phone detects not only your network, but also other access points, which may have similar names, for example, mydoms and mydons. Make sure you are connecting to your network and not your neighbor's.

If up to this point there have been no problems with authentication, first try rebooting your smartphone and the router itself; perhaps there was some kind of temporary glitch. Is your phone still unable to connect to your Wi-Fi network? Delete in WLAN settings saved network and try to reconnect.

The example discussed above is the simplest, but more often everything is a little more complicated, being associated with incorrect settings the router itself.

Router settings

You connect to the network, but the phone does not connect to Wi-Fi, it says saved WPA2 or WPA. After a few seconds, the “Authentication Error” message appears. If the password is correct, there is most likely something wrong with the router's security settings. It may also be that the phone says “Saved,” but the connection is still not established. It’s easy to get into the router settings; you just need to go to the internal address in the browser 192.168.0.1 or 192.168.1.1 . It is more difficult to understand its interface, since different models routers, it can differ significantly.

By default, the login and password are used to log in admin/admin(look at the bottom of the case). Before making any changes to your router settings, remove the network from your phone or at least, disconnect. It is also advisable to create a backup copy of your router settings - if you suddenly get confused or do something wrong, you can always restore. After making changes to the router settings, it also requires a reboot.

Region

Now a little more about setting up an access point. First, try changing the region.

In the settings this option is located in the section Wi-Fi - Advanced Settings, c – on the “Wireless” tab. In other models it may be located in a different location. In short, you need to first study the interface of your router. In the regional settings, the country in which you live should be selected, although this is not critical. Save your settings and reconnect.

Network mode

Much more important setting, which may prevent the gadget from connecting to Wi-Fi is the wireless network operating mode. This is perhaps the main reason for authentication errors when connecting to Wi-Fi on a phone that may not support the current mode. There can be several modes: B, G, N, etc. If you have B/G/N mixed, install it, and you can try experimenting, choosing one or the other mode. Pay attention also to the channel. It should be auto.

Security Settings

Find the security section in your router settings and try playing with the settings. It is advisable that the network authentication be set to WPA/WPA or WPA-PSK (if there is mixed, enable it), encryption is AES, the key contains only latin characters, only numbers or both.

After changing the router settings, reboot it and re-establish the connection on the phone. Unfortunately, the two methods described above can cause problems with connecting other devices, such as a laptop or TV, if they do not support the changed parameters, so everything is not so simple here. If the password has changed, in any case it will also have to be changed on other devices.

Channel width

It is highly unlikely that this will help solve the problem, but just in case, you can try changing the Wi-Fi network channel width. In routers D-Link setup look in the subsection Wi-Fi Additional settings , in TP-Link – Wireless Settings – Channel Width. Available options usually several: 20MHz, 40MHz, Auto and others.

Filtering by MAC address

Each electronic device has its own unique identifier - MAC address. Find the MAC filter subsection in the router settings and make sure filtering is disabled.

If it is enabled, determine the MAC address of your smartphone, check the settings in the router and, if necessary, remove the phone from the “black” list or, conversely, add it to the “white” list.

Phone stuck on getting IP address

Another common problem is the device getting stuck at the stage of obtaining an IP address. The phone does not connect to Wi-Fi, it says “Obtaining an IP address,” and this message can appear for hours. The cause of the problem, again, may be hidden either in the settings mobile device, or router. The latter is indicated by problems connecting to Wi-Fi and other devices. Responsible for distributing IP addresses to devices, changing the pool of addresses and the router itself in the router DHCP server. If it is disabled, your device will never receive an IP address.

Is DHCP enabled?

Let's check the operation of DHCP. The location of this setting differs in different router models. In TP-Link you need to look for it in the section The local network or LAN, in D-Link it is usually located in the subsection Network – LAN.

The mode must be selected "Allow". Instead of a drop-down menu, the “Enable” and “Disable” radio buttons can be used in the router settings. Here, we believe, everything is clear too.

Static IP

You can solve the problem of “eternally” obtaining an IP address by setting a static IP in the advanced connection settings of your device.

To do this, click on your connection in the list of networks, select Change network – Advanced settings – DHCP – Custom(over earlier versions Android will need to check the “Static” box).

In the panel that opens, enter the IP address 192.168.X.YYY in the appropriate fields, where X is 1 or 0, this depends on the address at which you access the router settings (you can try both options), and YYY is any number from 0 up to 255.

The gateway must match the address of your router, leave the prefix length at default, do not touch DNS 1 (8.8.8.8) and DNS 2 (8.8.4.4). If you have other data instead of those indicated in brackets, do not change them either - they are given by your provider. The exception is DNS 2, which can be left blank. If something is unclear or you doubt the correctness of the data entry, it is better to contact your provider’s support service - it is their direct responsibility to connect their clients’ devices to the network.

Automatic error correction tools

If you encounter an authentication error when connecting to Wi-Fi on Android, but it works for you Mobile Internet, install from the Store Google Play application Android WiFi Fixer. This utility is an analogue of the connection troubleshooting tool in Windows and is designed to find and automatically correct Wi-Fi connection errors on mobile devices running Android control. Once launched, the application checks everything network settings and tries to connect to Wi-Fi bypassing it.

Other reasons

The above examples of problems and how to fix them are the most common. In reality there may be more reasons. Why doesn't my smartphone connect to Wi-Fi? Perhaps you installed a proxy server program that was not fully developed, caught some kind of virus, rooted the device, changed the firmware, etc. Here you need to look at the circumstances. There have been examples where wireless connection blocked antivirus programs.

In general, if the connection is lost after making some changes, most likely this is the reason. If all else fails, reset the device to factory settings, remembering to first create backups important applications and data.

Well, the most unpleasant thing that can happen is failure Wi-Fi adapter. In this case, not only yours, but also other wireless networks will not be detected. There is nothing to do here; you will have to take your gadget to the service center.

When connecting to a Wi-Fi channel, devices running on a mobile Android platform, various problems may occur, the most common of which is WiFi authentication failure.

Most often, problems arise due to incorrect settings in or in the operating mode of the router, as well as the channel selected for the Wi-Fi network. When you try to connect to the network using an Android tablet or phone, you may see some errors.

WiFi (Android)

This is an authentication issue that typically shows "Disabled" and the device is Wi-Fi networks does not connect.

This device is often a smartphone, but WiFi authentication errors on tablets are just as common.

Endless acquisition of IP addresses

The connection status is: “Obtaining an IP address” or “Connecting”. However, the device does not connect to the network. As you can see, the WiFi authentication error is not the only one, although it is common.

Error “Saved, protected by WPA\WPA2”

A device running Android OS connects to the router via Wi-Fi, but the Internet still does not work. Websites do not open in the browser. Most often in such cases the network level indicator is inactive (for example, gray, but before it was blue). Next, we will try to figure out how to authenticate WiFi, as well as eliminate all the problems described above.

Problem solving

Before you start making changes to any settings, we recommend that you simply restart your device that refuses to connect.

There is a possibility that we are dealing with some kind of glitch, and rebooting the device will help. If it doesn't help, let's look at other options. If everything connected before, but now it doesn’t want to (and you haven’t changed any settings), we recommend changing the channel for working with the wireless network. Perhaps appeared new router nearby, whose network interfered with the usual connection.

This can most often be done in the “Wireless” tab. Or in another place where you usually configure your wireless network settings. The procedure is as follows: change the channel number, save the settings, reboot the router, and then try to connect.

The device connects, but the Internet still does not work

You see the status “Connected”. Everything seems to be correct, but the Internet is still not working. First of all, you need to make sure that the network is actually present on the router. Often a similar problem occurs when you first connect some other device to Wi-Fi. If it connects, but the Internet refuses to work, most likely we have a problem with incorrect given settings on the router. If another device goes online, try our other tips in action.

WiFi Authentication Error: Details

If you can see an error on your phone screen that says "Authentication", it is most likely we're talking about about problems associated with incorrectly configured security settings or an incorrect password.

When writing your password, adhere to the specified letter case. If you enter the password correctly, check your security settings. Set the security type to WPA2. The password must be exactly 8 characters long. Also, try changing the operating mode of your wireless network. You can change it in the same place where we selected the channel (router settings).

Reboot your router and save the settings after each change you make.

It's also worth checking your region settings. Please indicate the country you are in. Check if it works specified device with others Wi-Fi hotspots. It is possible that the problem is with your tablet or phone.

What if it's a virus?

We have not mentioned above that WiFi authentication error may occur due to system file violation and dynamic libraries various malware(in other words, viruses) that attack your mobile device.

In this case, immediately apply comprehensive measures to combat the specified error. There are several programs that can solve similar problems without much time investment. Just follow all instructions antivirus program after its launch. Use only proven applications, and then the likelihood of all sorts of malfunctions in the operation of your mobile device (including wireless network detection) will be significantly reduced.

We may not have described a solution for all Wi-Fi connection problems, but we tried to focus on the most common situations. For more detailed information contact your provider or service center.

Authentication error when connecting to WiFi is one of the most common problems that is associated with a problem connecting the device to the router. Let's take a closer look at the error itself and what to do if it occurs.

Why does this problem occur?

An authentication error occurs when the router and device (connecting subscriber) cannot identify each other for a number of reasons. The main indicator of such a problem is that when connecting to a network it writes “Saved, not connected” or simply “Saved”.

This problem often occurs on devices running operating system"Android" and on regular personal computers and laptops. Let's take a closer look at everything possible ways troubleshooting. Follow the instructions and tips to set up correct connection with the Internet.

Password verification

Often the user cannot connect to the network because the password was entered incorrectly. Due to the fact that the default access window hides the entered password characters, the user may make a mistake and enter one of the characters incorrectly. Check the “Show password” checkbox to see all the characters you enter. On computers running Windows OS, hold down the key located on the right in the text field to see the characters of the entered router access password.

If you have forgotten your password, you need to use the router settings.

To do this, follow the instructions below:

Log in using your personal computer or laptop to any of the browsers;
Enter the router's local address in the address bar. Look at the address at the bottom of the router or in its manual. If you do not find information about the local host, use the command line. Turn on the Run window. In the text field, enter "cmd" (without quotes). Press Enter. In the console dialog box that opens, enter the text “ipconfig” (without quotes) and press Enter. Find the “default gateway” item and look at the address in the column opposite - this is the local identifier of the router on the network;

Enter your login information into the router settings (login and access password). If you have forgotten this information, contact your network provider;
After logging in you will be taken to the tab quick settings router. The settings menu differs depending on the router model. In some cases it may be presented in English;
Go to the advanced settings tab and in the WiFi field, select security settings, as shown in the figure below;

In the encryption key text field, you can open access find out what encryption key the router uses;

Turn off the settings menu and try connecting to the router by entering the access key you just viewed.

Checking the router connection

If after administration correct password I still get an authentication error, the next step is to check if the router is connected to the network correctly. The figure below shows a basic router connection diagram. Make sure all wiring is connected as shown in the figure. Otherwise, reconnect. After this, reboot all devices and try connecting to the router again.

Also, the problem of authentication error may occur on the provider's side, so it is appropriate to call the telecom provider back. Perhaps they can solve the problem on their own or send competent specialists to you who will solve the problem.

Reinstalling driver software for your computer's network adapter

In some cases, an authentication error occurs on computers with outdated drivers network adapter (network chip). Follow the instructions to update the driver software:

Enable the system device manager window. To do this, right-click on the “Start” button and select “Device Manager”;

Find the tab with all devices network adapters and unfold it;

Find your WiFi adapter in the list of devices. Right-click on it and select driver update. The driver software installation process will begin and complete automatically. Restart your router and computer and try connecting to the network again.

Reflashing the router

To solve the authentication problem, you can try to reflash the router. To do this, you need to download the new firmware version from the manufacturer’s official website. Typically, the user only needs to enter the driver model and the approximate date of purchase. Next, the site system automatically detects the software used and offers to download more current version. To install the software, simply run the downloaded executable file and wait for the installation to complete. Reboot all devices and try connecting again.

You can also reflash Wi-Fi in its settings menu. Find the field that shows the version you are using software and click on the update button to start the installation process for more new version firmware.

If the problem cannot be solved, you can always roll back the latest one in the router settings installed version software and return the router to factory settings. However, in this case it is necessary to set again New Password and level of data security.

Setting up router and device encryption

The identification problem may also arise due to the fact that the router and Personal Computer or the user's laptop is used fundamentally different variants network data encryption. This happens when, during the first setup of the router, inexperienced users set different settings security and encryption.

To troubleshoot the problem, follow the instructions:

Go to your router's settings menu. You can read how to enter the settings in the first instructions of the submitted article;
Go to the security tab and check what encryption mode the router uses when connecting to the computer;

Now enable the computer to router connection window on the desktop toolbar. Select your router from the list of devices and see what encryption technology your PC uses to establish a connection. If these technologies are different, then in the router settings, change the encryption mode to the one used by the computer. Reboot your devices and connect again. The problem will be solved.

This way you can quickly solve the problem with identifying your computer when trying to connect to the router.
