One of the most common problems when connecting an Android phone or tablet to Wi-Fi is an authentication error, or just a “Saved, WPA / WPA2 protected” message after trying to connect to a wireless network.
In this article, I will talk about the methods known to me to fix the authentication problem and still connect to the Internet distributed by your Wi-Fi router, as well as what can cause this behavior.
For assistance, contact the point manufacturer or router. . This alert notification is enabled or disabled in the app settings. This alert notification is defined in the app settings. To clear this message, follow these steps.
Connecting to an access point using the default network name may present a security issue. This access point usually uses all default security and management settings. If you are using a personal network, change the security settings and the network name to improve network security.
Saved, WPA/WPA2 security on Android
Usually, the connection process itself when an authentication error occurs is as follows: you select a wireless network, enter a password for it, and then you see a status change: Connecting - Authentication - Saved, WPA2 or WPA protection. If a little later the status changes to “Authentication error”, while the connection to the network itself does not occur, then something is wrong with the password or security settings on the router. If it just says "Saved", then it's probably the Wi-Fi network settings. And now, in order, what can be done in this case to connect to the network.
File sharing and printers allow other computers on the network to access resources on your computer. To clear this message and restore network shares on logout, follow these steps: If you receive a message with a card that does not detect a network, the card has been removed or not installed. The card may be removed or not installed.
- Click "My Computer" and select "Properties".
- Select Hardware.
- Click "Device Manager".
- Select "Network adapters".
Important note: When changing the wireless network settings on the router, delete the saved network on your phone or tablet. To do this, in the Wi-Fi settings, select your network and hold it until a menu appears. There is also a Change item in this menu, but for some reason, even on the latest versions of Android, after making changes (for example, a new password), an authentication error still appears, while after deleting the network everything is in order.
To check the path and name, follow these steps. This authentication error is usually caused by incorrect server credentials. To resolve this error, follow these steps. The ID specified must match the ID that was issued by the certificate and registered with the authentication server used by the authenticator. This requirement depends on the authentication server and usually means that the authentication server must know the recipient of the certificate as a certificate authority. You must be logged in with the same username that was used when installing the certificate. Click Next to select a different certificate from the list of installed certificates, or specify a different server or certificate name. Click "Connect" and try to connect to the network and authenticate with the server.
- The certificate must be valid for the authentication server.
- Select a profile from the list of profiles.
- Click Properties to open the General Settings page.
- Click "Next" to open the security options.
- Enterprise security selected.
- Select a profile.
Very often, such an error is caused precisely by entering the wrong password, while the user can be sure that he is entering everything correctly. First of all, make sure that the Wi-Fi password does not use Cyrillic, and that you respect the case of letters (large and small) when entering. For ease of verification, you can temporarily change the password on the router to a completely digital one, you can read how to do this in the instructions for setting up the router (there is information for all common brands and models) on my website (you will also find there how to enter in the router settings for the changes described below).
Router settings for phone connection
Authentication failed because the authentication clock expired while authenticating this mobile station. If the rogue access point does not exist, is not suspected, click the profile in the profile list. Click Connect to connect to the network and attempt to authenticate with the server. This error occurs when the authenticator does not accept profile credentials. To resolve this issue, contact your administrator.
Solving problems with an authentication error on your device
Go to the management console. In any case, the IDs that need to be filled in are the IDs of your email address. This makes it easy to send email from a non-free external connection. Go to your email account management console.
The second common option, especially for older and budget phones and tablets, is the unsupported Wi-Fi network mode. You should try enabling 802.11 b/g mode (instead of n or Auto) and try to connect again. Also, in rare cases, changing the region of the wireless network to the United States (or Russia, if you have a different region installed) helps.
Make sure the service is activated. You can now customize your email software with the following new settings. Check your wireless connection. The first step is to try to connect another device to the same network to check if the wireless function is correct and to check if the router is configured correctly.
Save changes and return from settings. Check the strength of the wireless signal. The performance of a wireless network depends on signal strength. You need to connect to a place where the signal is strong. Make sure your firmware is up to date. Try resetting your device to factory settings.
The next thing to check and try to change is the authentication method and WPA encryption (also in the wireless network settings of the router, the items may be called differently). If you have WPA2-Personal installed by default, try installing WPA. Encryption - AES.
Another method suggested in the comments - try setting a Wi-Fi network password consisting of numbers only, can help.
And the last way, which you can try in case of emergency, is to automatically fix problems using the Android WiFi Fixer application (you can download it for free on Google Play). The app automatically fixes many of the bugs related to the wireless connection and, judging by the reviews, it works (although I'm not entirely sure how).
Error: 619: The specified port is not open. Error: 629: It has been disconnected from the selected number's computer. Error: 633: The modem is already in use or is not configured to dial an external phone number.
- Was the computer restarted after installing the modem?
- If not: do it.
- Isn't there a microfilter in front of the modem?
- Modem error?
- The cause of this error is an incorrect connection setup.
- Check your modem and phone number.
It is not uncommon for users to experience an authentication error when connecting to WiFi on Android devices. Most often, it is due to an incorrect password entry, although situations where a previously working connection suddenly refuses access also occur. About why this happens and how to deal with it - later in the article.
Causes of an Authentication Error
Any secure network implies the presence of a key - a code word that gives the user the right to receive and send information. If you enter the wrong password, then when connecting to Wi-Fi, the system will write: "Authentication error" and the connection protocol will be disrupted. An incorrectly entered combination of characters is the most common problem. To avoid this, it is recommended to remember:
The most common reason for this is modem suspension. . Error: 680: No beep. Is the service already active? - If not, we can call and see if the line is ready or wait. Does the signal, for example, come through the central unit? . Error: 692: Hardware failure in the domain.
Problem with Android device firmware
Make sure your computer has network adapters - if so, disable them in Device Manager. 720 errors have been known to occur in the event of problems with the firewall or antivirus program.
- Remove the floppy disk software.
- Other ways to remove this error are described in the section: Error 720.
- The connection attempt was unsuccessful.
- letter case matters;
- you need to check the input language;
- replacement of letters like "s" English with "s" Russian is unacceptable.
If, even after entering the password correctly, the device does not connect to Wi-Fi, the authentication error may be on the side of the router. Depending on the characteristics of the connected device, the following can be checked during connection:
Error: 749: Invalid phone number. The phone call properties are set incorrectly. . Error: 756: This connection has already been selected. We are creating a new Internet connection, the old connection is broken and can be deleted. Error: 777: The connection attempt failed because the modem or other device connected to the remote computer is damaged.
Error: 797: The connection failed because the modem was not found. To disable network adapters, go to the control panel and find the "System" icon, click on it. Most obviously, the modem was connected before the drivers were installed. We remove the drivers and reinstall. Let's remember to connect the modem when we are asked to do so. Should modem drivers be installed? - check, install. Sometimes it's worth creating a new connection. It is also possible that this error occurs when the modem is faulty.
- Go to the "Hardware" tab and click the "Device Manager" button.
- In the hardware tree, click the NIC separator.
- Right click on the backup NIC and turn it off.
- Restart your computer to remove the installation.
- Network card drivers installed.
- Install them.
- Disable network adapter - enable it in device manager.
- Suspended voice gateway.
- network SSID;
- MAC address of the router;
If at least one of the items does not match the data stored in memory, the smartphone or tablet will interrupt the connection protocol for security reasons. This discrepancy can be caused by:
Using WiFi Fixer
Follow the link and click the "Add" button. In the "Create a new connection" window, select "Connect to the network using broadband" and click "Next". In the next window, enter a name for the call and click Finish. It has also been verified that the new connection is set to the default value and that the option is always selected: Always select the default connection.
The term "Authentication Failure"
As a result of our work, an Internet connection window and an icon on the desktop will appear on the desktop. You enter a username or password, but do not change anything in the connection settings. Another user connects with your username and password - this is a very serious violation of the rules - never give data to anyone.
- Re-enter your username and password.
- Everything looks correct and the error is still happening.
- failure of settings in the router;
- malicious substitution;
- new.
Regardless of the cause, you need to troubleshoot the problem comprehensively: both on the connection device and on the router.
Android Devices: Troubleshooting Authentication
So, there was a Wi-Fi authentication error on Android: what to do in such a situation? First of all, you need to make sure that:
After removing the keys, turn off the computer and turn it on. . Error: 718: Timed out waiting for a valid response from the remote computer. We usually have an empty user field in the connection settings, please enter the relevant details and connect to the Internet. Error: 735: - The specified address was rejected by the server.
You created a connection but don't have a network adapter, or you created a connection and then installed a network adapter. Error: 741: The local computer does not support the required type of data encryption. Error: 769: The specified destination is not available.
- the connection is made to that network;
- the password was entered correctly;
- Is there a limit on the number of connected devices?
- You are the only one with connection problem.
You can try to enter the password again. To do this, go to Settings - Wireless networks (wireless connection - depends on the version of Android). In the window that appears, find and hold down the name of the SSID, select “change settings” in the drop-down list. After entering a new password, try to connect again. If this does not help, read on.
In case it is your phone that does not connect to WiFi, the authentication error occurs on the device itself. To resolve this issue, you will need to take several steps.
Today, you can access the Internet from your phone not only using a 3G network, using a radio module. An increasing number of devices are equipped with a Wi-Fi module. It allows you to connect at a higher 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 connecting to Wi-Fi, the android displays 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 enough to enter the correct password, and the problem will be solved by 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. This can be done both 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 higher):
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 even for inexperienced users who do not know the password.
The principle of operation of this encryption system is approximately as follows.
In 2004, a new encryption system was created, 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 configuring the TP-Link router, can be found through the WEB interface, in the field called "Mode".
Establishing a Wi-Fi connection on Android
Connecting an Android cell phone is usually straightforward. 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.
A common problem when connecting an Android device to a Wi-Fi network is an authentication error. There is also a notice: "", " Saved, Protected" or " Saved, WPA/WPA2 security". In this article, I want to tell you: what is the authentication procedure, why such an error occurs when connecting to Wi-Fi, and what are the ways to fix it.
Authentication procedure
Wi-Fi authentication is a security key verification. After entering the data (in this case, the password from the Wi-Fi access point), the identifier is checked. If it matches the specified one, then the device connects to the wireless Internet.
This procedure is necessary to prevent unauthorized access to a private Wi-Fi network.
Reasons for the error
The activation of the access point looks like this: Connection - Authentication (Authentication) - "Saved, Protected".
A little later, the status changes to " An authentication error has occurred" or " Authentication error"And the connection naturally does not occur.
There are only two main reasons why "Authentication failed" occurs when connecting to Wi-Fi on Android.
- First associated with the wrong ID. This means that the password for the access point was entered incorrectly. Also, an error is possible after changing the Wi-Fi password in the router itself - when, when automatically connected to a point, the old password is pulled up.
- Second associated with a data encryption type mismatch. In this case, the problem is in the security settings in the router itself. Also, an error may occur due to the unstable operation of the device itself (which is especially found in cheap models, for example, when connecting a large number of devices to Wi-Fi).
Debugg
For reference! As an example, a Samsung Galaxy S4 smartphone running Android 5.0.1 and a TP - Link TL-WR740N router are used. The interface of your devices may differ, but by analogy, you can easily find the information you need.
In an Android device
To start:
Advice! If you are sure that the password you are entering for the access point is correct and you are not mistaken when writing it, the problem is probably in the data encryption by the router. In this case, you do not need to do any manipulations on the tablet.
In the router settings
Important! The inability to connect Android to a Wi-Fi network and, as a result, "Authentication error", may be due to the unstable operation of the router itself. Due to overload, line failures at the provider, power surges, etc. the router may be malfunctioning. This is cured by a simple reboot of the device.
Connect the router to your computer/laptop using the same Wi-Fi or LAN cable:
Advice! Do not forget to reboot the router after each manipulation in the settings for the changes to take effect. After each change in the settings, try to reconnect to the network on Android.
Also note the authentication version. Try setting WPA-2 instead of WPA and vice versa. In this case, use encryption - AES.
