12 methods to fix wifi authentication problem on Android


  • Double check for duplicate networks

Often, users get a wifi authentication error when the username and password are not valid. You should check if there are similar or duplicated Wifi network names. It is possible that you may accidentally click on the wrong wireless network. If this is the case and it causes confusion, try renaming your Wifi network, then connect your device.


  • Restart the router

One of the most obvious things to do is to restart your router to solve a wifi authentication problem. Just turn it off, wait a few minutes, then turn it back on. This will solve any technical problems that your router may have. However, don’t forget to “remove the network” on your Android device first. This feature will get rid of your existing network profile.

  1. Settings 
  2. Wireless and networks 
  3. Wifi.

All you have to do is support and maintain the wireless network to which you want to connect. You will then display a context menu from which you can click on “remove network”. Once you have completed the two steps mentioned above, add the Wifi network again and try to reconnect.


  • Modify the security protocol

This solution seems much more complicated than it really is. As long as you know the correct username and password for your Wifi network, you are good. In order to change your router settings, simply check whether the security protocol indicates WPA2 or WPA. If WPA is displayed, change it manually to WPA2 and, if it displays WPA2, change it to WPA. Once this is done, repeat the “remove network” process and add the wireless network again and the wifi authentication problem is solved.


  • Using the WPS

In case you are not familiar, WPS is the abbreviation for Wifi Protected Setup (formerly Wifi Simple Config) and serves as a network security standard, allowing you to connect your devices without entering the password each time you use Wifi. To solve a wifi authentication problem with this feature, follow the steps below:

  1. Go to Settings 
  2. Wireless and networks
  3. Wifi on your Android phone.
  4. Find “Advanced Settings”. You will see several options.
  5. Click on “WPS”. This can also be named as “WPS connection”, depending on your device.
  6. This will require a WPS configuration screen.
  7. Now press the “WPS” button on your router.

whaite a few seconds, try connecting your phone to the Wifi network, it should work.


  • Modify the configuration of the Wifi network

Most often, a wifi authentication error can result from an IP conflict. In this case, you simply need to change the default settings of your static IP Wifi network. Here’s what you need to do:

  1. In your phone, go to “Settings”.
  2. Click and hold on the Wifi network you want to connect to.
  3. Select the “Change network configuration” option. This can also be displayed as “Change network connection”.
  4. You will see the option Show advanced settings with a small box next to it. Tick this box.
  5. Scroll down to find “IP Settings”.
  6. The default setting is usually DHCP. Change this to static.
  7. An IP address section will be displayed just below.
  8. Delete everything that is there and enter the following information – 192.168.1. *** (insert a number between 1-225 in the space marked with three asterisks)
  9. Save the changes.

If this does not work for any reason, change the IP address to DHCP without disconnecting from Wifi.


  • Make sure that the Android device software is updated

Perhaps you have already checked this and done the necessary work. However, users tend to ignore notifications about software updates. And often, updates solve problems related to Wifi and therefore the problem of wifi authentication.
Therefore, if your Android device is running on older software, it is likely that connectivity will frequently decrease, be poor or show authentication problems. It is best to ensure that your device is running on the latest software and if not, you should update it as soon as possible by following the steps mentioned below:

  1. Go to Settings
  2. About the phone.

  • Create a new Wifi password

Faced with a problem of wifi authentication, this solution is not really a solution, but there is nothing wrong with trying it. We all have this sneaky family member who picks up our phone and uses it every time they have an opportunity. You never know if your password has been changed without your knowledge! It is also possible that you yourself entered an incorrect password because you forgot a certain insignificant character. So, it’s always a good idea to change the password from your router, then try connecting it to your device.


  • Put the phone in Plane mode

Normally, we find ourselves putting the phone in airplane mode on flights, or when we simply want to avoid incessant phone calls. However, this simple feature can sometimes help us solve a wifi authentication problem.

  1. Go to Settings
  2. Network Connections
  3. Wifi.
  4. Depending on your device, you may need to perform an additional step.
  5. click on “More networks”.
  6. You will see the “Airplane Mode” option.
  7. Check the box to activate it and try to reconnect your phone to the wireless network.

Another way to activate the Airplane mode is to simply scroll through the quick settings and press the Airplane Mode option.
Once this is done and you are connected to Wifi, you can reactivate your mobile data.
If there is a conflict between your mobile network and your wireless network, this solution should resolve it.

  • Delete old files (ROOT only)

ROOT or rooting is the process by which Android devices gain greater control over a legion of subsystems. So, if your Android device is rooted, deleting obsolete files can help solve Wifi connectivity problems.

  1. Download and install “ES File Explorer” on your device.
  2. Allow root permissions if prompted.
  3. Navigate to “Root Explorer” in the menu and then go to / data / misc / dhcp /
  4. Delete all the files you see.
  5. Restart your Android device.
  6. Try to connect to the wireless network.


  • Check the maximum number of devices supported by the modem

There is no standard number of devices that a modem can support. The number varies from one modem to another. Check the maximum number of devices supported by your wifi modem. Few routers can be configured manually to support more devices.
If your modem is capable of the above, you can check the maximum number of supported devices and switch to a larger number from the router settings.

  • Reset network settings

You may not be sure what exactly is causing the wifi authentication error. Reviewing all possible reasons and solutions can be a difficult and tedious task. One easy thing to do is to reset all your network settings, including Bluetooth connections, Wifi and cellular networks. Follow the steps below:

  1. Go to Settings =>> Backup and Reset =>> Reset Network Settings.
  2. Click Reset Settings.
  3. This may take a little time.
  4. Finally, return to the main Wifi menu and reconnect your device to the network.

If you are concerned about losing data, be aware that this solution will not delete your data. However, what will be deleted is all your previously added networks, including Bluetooth devices and cellular data information.


  • Perform a factory reset
Despite all the solutions listed above, if your Android device still fails to connect to the wireless network, this should be considered your last resort. To perform a factory reset, you must access 

  1. Settings
  2. Backup and Reset
  3. Reset Factory Data. 

After that, reconnect to the wireless network.

Closing Remarks

As mentioned above, there is no single solution to a Wifi authentication problem. What might work for you may not work for someone else and vice versa. This is because the reason for this problem of wifi authentication varies. It is better to try several solutions and see what works with your wifi authentication problem.
