Error connecting to Wi-Fi Android smartphone. I can't connect to Wi-Fi from my phone

One of the common problems when connecting an Android phone or tablet to Wi-Fi is an authentication error, or simply the message “Saved, WPA/WPA2 protected” after trying to connect to a wireless network.

In this article, I will talk about the ways I know to fix the authentication problem and still connect to the Internet distributed by your Wi-Fi router, as well as what may cause this behavior.

Contact the point manufacturer or router for assistance. . This alert notification is enabled or disabled in the app settings. This warning notification is defined in the application settings. To clear this message, follow these steps:

Connecting to an access point that uses the default network name may present a security issue. This access point typically uses all default security and management settings. If you are using a personal network, change the security settings and network name to improve network security.

Saved, WPA/WPA2 protection on Android

Typically, the connection process itself when an authentication error occurs is as follows: you select a wireless network, enter its password, and then see the status change: Connection - Authentication - Saved, WPA2 or WPA protection. If a little later the status changes to “Authentication Error”, but the network connection 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 due to the Wi-Fi network settings. And now, in order, what can be done in this case to connect to the network.

File sharing and printer sharing allow other computers on the network to access resources on your computer. To clear this message and restore network shares when you log off, follow these steps: If you receive a message with a card that is not detected by the network, the card has been removed or not installed. The card may have been 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 in the router, delete the saved network on your phone or tablet. To do this, in Wi-Fi settings, select your network and hold it until a menu appears. There is also an “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 fine.

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 specified ID 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 typically means that the authentication server must know the recipient of the certificate as the certificate authority. You must log in with the same name 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 Security Options.
• Enterprise security has been selected.
• Select a profile.

Very often, such an error is caused by an incorrect password entry, 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 when entering you respect the case of letters (capital and small). For ease of verification, you can temporarily change the password on the router to a completely digital one. You can read about how to do this in the instructions for setting up the router (there is information for all common brands and models) on my website (also there you will find how to log in in the router settings for the changes described below).

Router settings for connecting a phone

Authentication failed because the authentication clock expired while authenticating this mobile station. If the rogue access point does not exist or is not suspected, click the profile in the profile list. Click Connect to establish a connection to the network and attempt to authenticate with the server. This error occurs when the authenticator does not accept the profile credentials. To resolve this issue, contact your administrator.

Solving problems with authentication errors on your device

Go to the management console. In any case, the identifiers that need to be filled in are the identifiers of your email address. This makes it easy to send email from a non-free external connection. Go to your email management console.

The second common option, especially for older and budget phones and tablets, is an unsupported Wi-Fi network mode. You should try turning on 802.11 b/g mode (instead of n or Auto) and try connecting again. Also, in rare cases, changing the wireless network region to the USA (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 connecting another device to the same network to test the correct wireless function and to verify that the router is configured correctly.

Save your changes and return from settings. Check your wireless signal strength. Wireless network performance 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 rebooting your device to factory settings.

The next thing to check and try to change is the authentication method and WPA encryption (also in the router’s wireless network settings, the items may be named 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 only numbers, it may help.

And the last method, which you can try if something happens, is to automatically fix problems using the Android WiFi Fixer application (can be downloaded for free at). The application automatically corrects many errors 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?

• This error is caused by an incorrect connection setup.
• Check your modem and phone number.

Users often experience an authentication error when connecting to WiFi on Android devices. Most often it is caused by an incorrect password entry, although situations where a previously working connection suddenly denies access also occur. Read more about why this happens and how to deal with it later in the article.

Reasons for 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 the modem hanger. . Error: 680: No dial tone. Is the service already active? - If not, we can call and find out if the line is ready or wait. Does the signal originate, for example, 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 appear when there is a problem with the firewall or antivirus program.

• Uninstall the floppy 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;

• Replacing letters like “s” in English with “s” in Russian is unacceptable.

If, even after entering the absolutely correct password, the device does not connect to Wi-Fi, the authentication error may be on the router’s side. 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 not set correctly. . Error: 756: This connection is already selected. We are creating a new Internet connection, the old connection is damaged 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 Control Panel and find the System icon, click on it. The most obvious thing is that the modem was connected before installing the drivers. We remove the drivers and reinstall. Let's remember to connect the modem when asked to do so. Should drivers be installed for the modem? - 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 equipment tree, click on the network cards separator.
• Right-click on the backup network card and turn it off.
• Restart your computer to remove the installation.
• Network card drivers are installed.
• Install them.
• Disable the network adapter - enable it in Device Manager.
• Paused voice gateway.

• Network SSID;

• Router MAC address;

If at least one of the points does not match the data stored in memory, the smartphone or tablet will interrupt the connection protocol for security reasons. This discrepancy may be caused by:

Using Wifi Fixer

Follow the link and click the "Add" button. In the “Create a new connection” window, select “Connect to a network using broadband” and click “Next”. In the next window, enter a name for the call and click Done. It was also checked that the new connection is set to default and that the option is always selected: Always select the default connection.

The term "Authentication Error"

As a result of our work, an Internet connection window and an icon will appear on the desktop. You enter a username or password, but do not change anything in the connection settings. Another user connecting with your username and password 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.

• settings failure in the router;
• malicious substitution;
• new.

Regardless of the cause, the problem must be resolved 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 your computer and turn it on. . Error: 718: Timeout waiting for a valid response from the remote computer. Usually we have a blank user field in the connection settings, please enter the relevant details and connect to the Internet. Error: 735: Ї - the specified address was rejected by the server.

You created a connection but you 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 data encryption type. Error: 769: The specified destination is not available.

• the connection is made to exactly that network;
• the password was entered correctly;
• is there a limit on the number of connected devices;
• You're the only one with a connection problem.

You can try to enter the password again. To do this, go to Settings - Wireless networks (wireless connection - depends on the Android version). In the window that appears, find and press the SSID name, select “change settings” in the drop-down list. Enter a new password and try to connect again. If this doesn't help, read on.
In case your phone does not connect to WiFi, the authentication error occurs on the device itself. To resolve this issue, you will need to take several steps.

When connecting to a Wi-Fi channel, devices running on the Android mobile platform may experience various problems, the most common of which is a 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 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 does not connect to the Wi-Fi network.

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 previously 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 a new router appeared nearby, the network of which 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 incorrectly configured 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 displays the message “Authentication”, most likely, we are talking 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 the specified device works with other Wi-Fi points. It is possible that the problem is with your tablet or phone.

What if it's a virus?

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

In this case, immediately apply comprehensive measures to combat this error. There are several programs that can solve such problems without much time investment. Just follow all the instructions of the antivirus program after you launch it. 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.

Users of tablet computers and Android phones often encounter this problem: the device does not connect to Wi-Fi, although you have entered the correct password. A message appears: " ". What to do in such cases?

First, make sure that the access point you are currently connecting to actually distributes the Internet. To do this, try connecting to it using other devices (laptop, tablet, etc.). If there is Internet on these devices, it means that the access point is working and the reason for the lack of Internet is different.

There may be several reasons (for example, an incorrectly entered password or a weak Internet signal), but we will look at the most common ones.

Problem with Wi-Fi due to router settings.

Changing the Wi-Fi channel of the router:

• go to the advanced settings of the router,
• change the channel to another, confirming your action by pressing the “Apply” or “OK” button,
• exit the router settings and try connecting the device to the Internet.

Often such a simple operation solves a problem with a Wi-Fi connection. If connection does not occur, try the following.

Change the wireless mode in the router settings.

By default, most routers set the settings to 802.11 b/g/n mixed mode. Select another mode: 802.11n, 802.11b, 802.11g. After each mode change, click the "Apply" button and check for Wi-Fi connection.

If this does not help and the Android device still does not pick up Wi-Fi and the Internet does not work, you will have to “work” with the settings of your smartphone (tablet).

The problem is in the Wi-Fi connection settings on the device (tablet, smartphone).

Algorithm for setting up Wi-Fi and Internet connections on Android:

1. go to “Settings” of your smartphone (tablet),
2. turn on Wi-Fi,
3. select the network you are trying to connect to without success,
4. press and hold the icon of this network with your finger: a message will appear on the screen prompting you to delete or change the network,
5. select the "Change network" option,
6. after a window appears with the words “Show password” or “Show additional options”, check the box offering to show “additional options”,
7. Check the “Proxy server settings” and “IP settings” indicators that appear. The “NO” option must be selected in the proxy settings. Sometimes, for various reasons, the “MANUAL” option is set in this field, which interferes with your successful Internet connection. If you change the proxy settings to “NO”, in most cases Wi-Fi starts working.

Incorrectly set date on Android device.

1. go to general settings and select the “Date and time” option in the “System” item,
2. uncheck the system suggestion “Auto-adjust date and time” and “Auto-adjust time zone”,
3. Set the correct date on your device to match the current time.

If these methods do not help, the lack of connection may be due to technical reasons. A weak smartphone, tablet, old version of Android OS or a very weak Internet signal - all this can affect the stability of Wi-Fi and the Internet.

Many Android users encounter this problem: when they try to connect to a Wi-Fi wireless network, the system displays the following message “Authentication error”. As a result, you cannot use Wi-Fi.

In this article, we will analyze the reasons for this unpleasant phenomenon, as well as ways to correct the authentication error.

Fixing Wi-Fi Authentication Error Without Third Party Apps

1. Check if you are entering the password correctly. Perhaps the keyboard layout is wrong, or you do not respect the case of letters (small or capital). This is the most common cause of this error.
2. Reboot your Android device and the router along with it (if you have access to it, of course). Perhaps the cause of the error is a short-term glitch that will disappear after a reboot.
3. See if you are connecting to the right Wi-Fi network. Sometimes the network names can be very similar, especially if your neighbors use the same provider. Perhaps you just made a mistake and are “storming” your neighbor’s Wi-Fi.

Fixing authentication error using Wi-Fi Fixer

Router settings

If the problem cannot be solved using the methods described above, then you need to dig deeper into the settings of the router itself on your PC.

Conclusion

Now you know how to fix authentication error when connecting to Wi-Fi on Android. If you have any questions, ask them in the comments and we will definitely help you.

Before you begin to find out why Wi-Fi or the Internet does not work, you should know (especially for those who have just purchased a Wi-Fi router) that it is not enough to just connect the provider cable to the router, you also need to configure it (set up the Internet and Wi-Fi network ). All of the methods described below are valid if Wi-Fi and the Internet were working for you before, and then suddenly stopped or you cannot connect a new device to Wi-Fi. For convenience, I divided the article into two parts, the first is devoted to the inability to connect to a wireless network, the second part will answer your questions if you are connected to a Wi-Fi network but there is no Internet.

Cannot connect to Wi-Fi network.

Reboot the router.

The first thing you need to do if you have problems connecting to a Wi-Fi network is to restart the router. To do this, simply disconnect the power supply from the router and connect it again after a few seconds. After 1-2 minutes. The device will boot, then try connecting to the wireless network again. To avoid such situations in the future, I recommend updating the router firmware (perhaps the manufacturer knows about the problem and fixed it in the new firmware).

Enabling the Wi-Fi module on the laptop.

Check if Wi-Fi is turned on on your laptop, I won’t bother, I described all the ways to turn on Wi-Fi in the article How to turn on Wi-Fi on a laptop .

Change the wireless network mode.

If you are trying to connect a device (laptop, smartphone) that is more than 5-7 years old, you must take into account that it may not support the modern Wi-Fi mode - n. Therefore, you need to switch the router to an operating mode that is supported by the device or enable mixed mode b/g/n. More details about Wi-Fi operating modes are described. In order to switch the wireless network mode, you need to go to the router’s web interface, go to the Wi-Fi settings and select the appropriate mode.

Removing a duplicate network SSID.

One of the possible problems of not being able to connect to Wi-Fi is a duplicate Wi-Fi network name (SSID). Suppose you come to your friends, their Wi-Fi network is called “Home”, you successfully connected to it. Time passed and you came across the same network name with other friends or at home. The laptop (this also applies to tablets and smartphones) tries to connect to the network using the previously saved password, but it fails because a new password is used for this name. To solve this problem, you need to remove the matching network from the list of saved Wi-Fi networks.

To do this, right-click on network icon in the lower right corner of the screen and select "Network and Sharing Center."

After this, you will see a list of saved wireless networks. If you see that the network you are trying to connect to is in this list, you need to remove it from this list. Select the network and click the "Delete" button. After this, you will need to enter a password to connect to the wireless network.

No Internet via Wi-Fi.

Internet payment check.

The simplest thing that can happen when the Internet is not working is that it’s time to pay for it or the provider is working on it. To clarify the situation, call your provider and find out if you have a debt for the Internet and whether work is being done on the line.

Static IP address.

One of the problems with the Internet not working may be that the registered static address does not have the network settings that are necessary. In this case, I recommend using automatic network settings retrieval. To do this, you need to go to the Network and Sharing Center. One way to do this is to right-click on network icon in the lower right corner of the screen and select "Network and Sharing Center".

Another way is to use hotkeys + , enter the command ncpa.cpl and press Enter.

It doesn’t matter which method you used, the result will be the same - the Network Connections window will appear on the monitor. Next, you need to double-click on the wireless connection. In the status window that opens, select “Properties” in the properties window “Internet Protocol Version 4 (TCP/IPv4)”

Problem with the router.

The Internet may not work due to a router failure; the simplest thing you can do is reboot it. There are situations when the router resets the Internet settings, in which case you need to connect to it via the web interface and re-enter the Internet settings, in order to experience fewer problems with the router in the future, I recommend updating its firmware.

Conclusion

In this article, I described all the ways I know to solve problems with Wi-Fi and the Internet. If these methods do not help you, you can describe the problem in detail in the comments and I, together with the readers of this site, will try to help you.
