The phone has a wlan connection error. WiFi Authentication Error - Effective Solutions

Today, you can access the Internet from your phone not only using a 3G network, using a radio module. All large quantity devices are equipped with a Wi-Fi module. It allows you to connect to more high speed, which allows you to watch videos and listen to music in real time.

Connecting to Wi-Fi with an Android phone is quite simple.

But it often happens that when connected to wifi android gives an error message. Most often, this message looks like this.

When this message occurs, there are several ways to resolve the problem.

The term "Authentication Failure"

To understand the reasons for this error, you first need to understand what a Wi-Fi authentication error is.

At its core, authentication is a procedure for verifying the authenticity of the entered password or a combination of login or password.

To connect a device such as a smartphone or tablet, it is usually sufficient to enter correct password and the problem will resolve itself. There are also situations when such an error may appear for some other reason.

Basic Mistakes

The most common cause of an error when connecting your phone to Wi-Fi is an incorrectly entered password. It is very important that you enter your password on your Android device with correct case and language. Since many people confuse the English "C" with the Russian letter "C". They have the same spelling, but their code designation is completely different. This often causes connection errors.

Quite often, the error occurs for a different reason, which means that the password is correct. A tablet or smartphone simply cannot negotiate with the router due to a conflict in the protection parameters (security type, encryption).

Solving the problem with connecting the phone to Wi-Fi

What to do if an authentication error occurs on an android phone? The way to resolve the problem with connecting the phone to the Internet via Wi-Fi depends on the reason that causes the authentication error.

First of all, it is important to simply check the settings of the router.

You can do this in the following way:

You can also set up an Internet connection without a password on Android. You can also do this in the router settings via the WEB interface, just leave the “Password” field empty.

After the slightest changes are made to the router settings, the old connection on a device running the Android operating system

must be removed to avoid the appearance of various conflicts. To do this, you just need to press your finger on the connection and hold it for a few moments.

If the above methods did not help, you just need to restart the router.

Rebooting the Router

One way to solve the authentication problem is to reboot the router. You can do this as in manual mode, using the "Power" button, and using the WEB-interface. To do this, you just need to go to any Internet browser that is installed on your personal computer.

Enter the correct password

Often, to connect to a Wi-Fi router, it is enough to enter the correct password. This is done as follows (on android version 4.0 and above):

If all operations were performed correctly, the correct password was entered, then there should be no problems with authentication. And you will be able to access the Internet without any difficulty.

Security and encryption method

Security in Wi-Fi networks is provided by specialized encryption systems developed by the IEEE Institute.

There are several types of encryption algorithms:

• AES/CCMP;
• CKIP;
• TKIP;
• WPA2.

The last three varieties are most often used to encrypt channels with data transmitted using Wi-Fi technology.

WEP technology was created relatively long ago, it is one of the most unreliable. Connecting to a channel protected by it is not difficult, not even very advanced users who do not know the password.

The principle of operation of this encryption system is approximately as follows.

In 2004 was established new system encryption, which is still used today - WPA / WPA2 (WPA2 - modified). Because it is extremely reliable.

b/g/n modes and wireless network channels

There are several modes in which the Wi-Fi network operates. Each has a different data transfer rate as well as coverage area.

Letter designations carry the following information:

n - the fastest mode (the maximum available speed is 600 Mbps);
g - medium-speed mode (maximum available speed - 54 Mbps);
b is the slowest mode (only 11 Mbps transfer rate is available).

It often happens that in order to normalize the work, it is enough just to switch the operating mode of the Wi-Fi router. Since some devices do not support the n mode, in which your router may work. For example, the iPhone 3GS supports working with a Wi-Fi router only in b and g mode. Thus, the inability to connect to the router may be due to incompatibility of operating modes.

Before connecting your phone to the router, check the specifications of the device. Perhaps they are simply incompatible.

I can't connect to Wi-Fi from my phone. Writes - authentication error

If, when you try to connect your phone to a Wi-Fi router, you see a message - “authentication error”, then there may be several reasons for this.

• the most common is that the password is incorrectly entered on the phone. Perhaps the error lies in the register. Or the password has been changed without your knowledge;
• The router is operating in a mode that is not supported by the phone. In this case, there are two ways out: switch the router to an alternative, lower speed mode, or simply purchase another phone;
• any changes were made to the settings of the Wi-Fi router, after which it was not rebooted through the WEB interface or using the "Power" button.

Router settings for phone connection

To connect your phone to a Wi-Fi router, you need to configure the router according to the instructions. It is only important to pay special attention to the choice of operating mode. Since not all smartphones today support work with n mode (600 Mbps).

This mode when setting router TP-Link can be found through the WEB interface, in the field called "Mode".

Establishing a Wi-Fi connection on Android

Connection cell phone running Android is usually not a big deal. But some models require turning off the 3G module in order to avoid interference.

The connection is made as follows:

What to do when Wi-Fi authentication fails on Android? First of all, you need to check that the password is entered correctly. If this does not help, you need to dig a little deeper. Most often, the solution to the problem lies on the surface; fixing it is quite simple.

Wired communication is becoming a thing of the past, so the topic of setting up devices for accessing the Internet via the Wi-Fi interface is becoming more and more relevant. Every year, the data transfer rate is getting faster, and errors occur less and less.

When connecting to a Wi-Fi channel devices running on mobile platform Android, you may experience different problems, the most common of which is the WiFi authentication error.

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

WiFi (Android)

This is an authentication issue that usually shows "Disabled" and the device does not connect to the Wi-Fi network.

A smartphone is often such a device, but a WiFi authentication error on a tablet is no less common.

Infinitely getting IP addresses

The connection status is as follows: "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.

"Saved, protected by WPA\WPA2" error

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

Problem solving

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

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

This can be done most often in the "Wireless" tab. Or in another place where you usually set up 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 still does not work. First of all, you need to make sure that the network is really present on the router. Often a similar problem occurs during the first time Connect some other device to Wi-Fi. In the event that it connects, but the Internet refuses to work, most likely we have a problem with incorrect 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 the phone screen that says "Authentication", it is most likely we are talking about problems associated with incorrectly set security settings, or with an incorrect password.

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

Reboot the router and save the settings after each change.

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

What if it's a virus?

We did not mention above that the WiFi authentication error can occur due to violation system files And dynamic libraries various malware(in other words, viruses) that attack your mobile device.

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

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

When connected to WiFi networks an authentication error occurs - 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 given 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 choose 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 type of encryption (authentication) WPA-PSKWPA2-PSK2 mixed is used.

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, a variant with one key phrase for all subscribers is used. The user himself sets the key, which is later required to connect to the network.

The second type of encryption is used by organizations that require a higher level of security. In this case, each trusted subscriber is assigned a unique passphrase. That is, you can 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 in the event of a mismatch between the encryption types and the entered passphrase.

Why an authentication error appears and how to fix it

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

Consider 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 write the IP of the router in the address bar. You can recognize it in the instructions or on the case of the device itself (carefully inspect it from all sides).

How to easily find out the IP address of a WiFi router: Video

You can also find out the IP of the router using command line. Press the key combination Windows + R, write 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 the browser and press "Enter". The system will then 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 additional windows will appear. We are interested in the section called "WiFi". In it you need to find the security settings. This is where you can select the type of authentication (encryption) and change the password.

Sometimes the authentication problem when connecting a computer to WiFi appears even if the key is entered correctly. This may mean that the router has failed or it just hung. This is fixed by simply rebooting the device. This can be done in the settings or by simply turning off the power for 7-10 minutes.

You should also check the channel on which the router is running. To do this, we return to the initial menu. In the WiFi section, click "Basic Settings" and find the line "Channel". It is recommended to set the value to "Automatic".

There are also cases when such an error appears not due to problems in the router and not due to an incorrectly entered key. In this case, check the settings in operating system.

OS Check on Authentication Error

The computer uses a Wi-Fi adapter to connect to a wireless network. It is because of its incorrect operation that WiFi network authentication problems may appear. First of all, you should check the presence and correct operation of the drivers. This is done in the device manager, which can be launched as follows. Find the shortcut "My Computer" 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 branch and see if your WiFi module is on the list. As a rule, the name has Wireless Network Adapter. If the device is labeled exclamation point the drivers are not working properly.

Hello dear friends!

Let's try now by joint efforts to understand another very popular problem “Authentication Problem”, or “Authentication Error”. You can see such an inscription when you try to connect your phone, smartphone, or tablet to a Wi-Fi wireless network.

We will consider the example of devices operating on the operating Android system. Most often, this problem happens on this particular OS. (or even just her).

The problem looks like this: You are trying to connect your phone or tablet to your home network (I wrote about how to connect in article), enter the password, and in the connection status you see the inscription “Authentication Problem” (or error, doesn't matter). That's all, the connection is not established, the Internet does not work accordingly.

If such a problem occurs when connecting to public Wi-Fi, then it is unlikely to be able to fix it, since we do not have access to the router settings. You can only check the password, you may have entered it incorrectly.

Solving the authentication problem

Now let's talk about the reasons why this problem may appear, and about solutions.

Restart your router

For starters, just restart your router. (unplug it from the power, and turn it back on after a few seconds). Maybe it's just some kind of glitch, and a reboot will help.

Checking the password

Very often, this problem occurs due to the fact that when connecting, we specify the wrong password. (or not being case sensitive). It is the password from WiFi networks. Not to be confused with the password that is used to access the router settings.

I specifically indicated the wrong password and I got a slightly different problem. First comes “Connecting…”, then “Authentication…”, then “ ” and everything repeats in a circle.

If you are sure that the password is correct, then it is still worth checking it. Look at the password in the router settings, I already wrote about how to do this.

It may even be that someone connected to your network and changed your password :). Whatever happens, your router.

Change the password, type of security and encryption

Most likely, the “Authentication Error” problem appears due to the fact that your phone or tablet is not friendly with the security settings that are set on your router. I have to enter the type of security, encryption and the password itself.

Try to set the security settings as indicated in the article.

If that doesn't help, then try setting different variants. For example:

WPA / WPA2 - Personal (Recommended) - this item is required.

version: Automatic.

Encryption: Automatic.

Try the password yourself only from numbers and strictly 8 characters.

Attention! After each change, delete the connection on the phone (tablet) and reconnect to the network, enter New Password. To delete a connection, press it with your finger and hold it for a while, a menu will appear there.

Also, do not forget to save the router settings and reboot it.

Operating mode (b / g / n) and the channel on which the wireless network operates

If the above methods did not help, then you should try two more options:

• Try different wireless network modes. I wrote a detailed article about this, therefore, I just give a link -.
• And the second option is to try to change the channel on which your network operates, the same detailed instruction is.

Afterword

Here are some tips, friends. Hope you were able to solve your problem.

Perhaps you have already encountered the “Authentication Problem” error and solved it in some way, in which case, please share your solution, or at least your opinion on this issue.

WiFi Authentication Error on Android is a fairly common error when the message “Saved, WPA/WPA2 secured” appears. Unfortunately, not every user understands what it means and how to fix it. At the same time, in order to solve it, you need to know why it occurs. Therefore, to begin with, you should answer the question, what is WiFi authentication.

WiFi authentication error on Android phone or tablet is a security key check. This check needed to improve network security. The point is that the point WiFi access has a sufficiently large range, so that not only trusted persons, but also intruders can connect to it.

Data encryption technology is used to prevent unauthorized connections. Therefore, in order to connect to the network, we need to enter a password.

Why does an authentication error appear

There are two reasons why a WiFi authentication error may occur on Android devices when connected to a network:

• Key entered incorrectly.
• Data encryption type mismatch.

The WiFi security password and encryption type are configured in the router settings. Therefore, on Android, it is only important to carefully monitor the correctness of entering the key. No more settings need to be made on the tablet or smartphone.

It should be noted that in addition to the above reasons why Android does not connect to the WiFi network and an authentication error appears, there may be other problems associated with the instability of the router itself.

Causes of WiFi Authentication Error: Video

The fact is that access points, especially budget models, can freeze and malfunction. Such failures can lead to problems on the provider's line, failures in the power supply network, overload when in large numbers subscribers.

Freezes can also occur as a result of long downloads of large files at high speed. In any case, this is fixed with a simple reboot of the router. Sometimes you may need to reconfigure your router.

Solving the authentication problem

So, if you have a WiFi network authentication problem on Android, then first of all you should check the correctness of the entered key. To do this, log in wifi settings on an Android device.

How to enter WiFi settings on Android tablet: Video

This will allow you to see the characters being entered. Carefully check the correctness of the key. If the password is entered correctly, but the WiFi network authentication error still appears on Android devices, then you should enter the router settings and check the encryption type.

Setting the encryption type in the router settings

In order to enter the router settings, you need to connect to it. You can do this using a laptop or a desktop computer, both via WiFi and using a cable. After connecting, open the browser and enter the IP of the access point in the address bar. As a rule, the address of the device is indicated on the case, in the instructions or in the box. In addition, it can be viewed in the network control panel.
