Why does my Phone say Authentication Problem when Connecting to WIFI

If your phone is displaying authentication error prompt when to you try to connect to a particular network, there is nothing to be so worried about. In most cases, you can quickly solve the issue on your own without getting professional help. But, of course, for this purpose, you need to know some quick tips and tricks, which I’m going to share with you today.

Are you fed up with the authentication error you get every time you try to connect your smartphone to a WIFI? If you are facing the issue repeatedly, it means there is a problem either with the router or the phone. First of all, you must make sure that the password you are entering is correct, and then you can try the solutions I’m going to share to get rid of the issue.

What is a WIFI Authentication?

WIFI authentication is essential whenever you want to connect your mobile to a protected WIFI network. And for this purpose, you need to enter the authentication password for the network device. If you are entering the right password but still facing the issue, then the problem may be addressed in several ways discussed in this article.

WIFI authentication is a process of making a ‘deal’ between your mobile phone and the router. The smartphone sends the connection request along with an encrypted password to the device (router).

The router cross-verifies whether the received password matches its saved password or not. If it does, the router allows the device to get connected. However, in some cases, the mutual deal fails, and you face the authentication error issue.

Why WIFI Authentication Occurs?

There could be several reasons that result in a WIFI authentication error, but the good news is that they can be quickly resolved. Before moving towards the solutions, let me point out the possible reasons for the authentication error you get while connecting to WIFI.

  • You might have recently updated your phone, and the issue is the improperly installed drivers.
  • The router is not functioning correctly and needs repair or change in settings.
  • The allowed number of users for the device is limited.
  • Your connection is unstable, or signals are weak.
  • The problem is with the phone’s hardware (it needs to be addressed by customer care or a technician).

However, you don’t need to worry as I have come up with several solutions to help you sort out the problem on your own.

Solutions for a WIFI Authentication Error

There are plenty of tricks to try when your phone is giving an authentication error prompt. I’ve carefully compiled a list of all the workable solutions and explained how to apply them in proper steps. Now let’s discuss all the possible solutions one by one.

Turn on Airplane Mode

Sometimes the mobile phone’s signals start interfering with the WIFI signals. All you need to do is to turn off the airplane mode and turn on the WIFI. Follow these simple steps:

  • Turn off WIFI and mobile connection and then turn on the airplane mode.
  • While staying in this mode, turn on the WIFI and mobile network.
  • Once it starts working, you can turn off the airplane mode.

Use Fixppo App

Fixppo is excellent software to troubleshoot and solve such issues. It works with both Android and iOS and helps you to resolve your smartphone issues. As the software is user-friendly and quite easy to use, so you won’t need any technician’s help.

Forget Network

  • Open the Settings app and choose the Wireless & Networks option. In some smartphones, you will have an alternative option, namely “Connections.”
  • Go to the WIFI option.
  • Find the network you are trying to connect with from the list of available networks.
  • Tap on the network you want to connect to.
  • Tap the Forget Network option.
  • Choose the network again. You will be asked to enter an authentication password.
  • Try to connect to the network by adding a password.
forget this network

When you open the Wireless & Networks option, you see a list of WIFI networks. These include both available networks and those you most connect with. Once you forget the network you are facing trouble with; the network settings are reset. That is the reason why you are asked to re-enter the password.

Modify Network from DHCP to Static

Sometimes the issue lies within the IP address conflicts. So, another workable yet straightforward solution involves switching the network settings from the default DHCP setting to static mode. Follow these steps to proceed:

  • In the Settings app of your smartphone, tap on the Wireless & Networks option.
  • Head over to WIFI. You will see a list of available networks there.
  • Choose the network you are trying to connect to.
  • Tap on the Modify option that lets you change the network settings.
  • Under the Advanced Settings option, you will find IP Settings. Change the IP setting from DHCP to Static.
  • Now enter the IP address of the router in the given space.
  • Save the settings and try to connect.

You can find the IP address of your router at the back of it. If the problem still pertains, you can apply other solutions. Read on to check them out.

Reset to Factory Settings

You might be getting the authentication error while connecting to WIFI due to software updates. If you have recently installed custom ROM, firmware update, or new software, you must try the “Reset to Factory Settings” option.

If you have any important data saved on your phone, you must create its backup or move it to your memory card or cloud. After that, you can proceed with resetting the factory settings by following these steps:

  • In the Settings app, tap on the Backup & Reset option.
  • Under it, you will find the Automatic Restore option. Make sure it is turned on.
  • Find and tap the Reset Factory Settings option in the list.
  • Now tap on the Reset Phone option and wait until your phone is rebooted.
  • Now, try connecting to the WIFI by entering the password.

Sometimes, if we directly reset the phone, all our data is lost. So, before resetting, you must create a backup.

Restart your Router

Another solution is to restart your router simply. Although it seems quite simple, it can prove to be a very efficient way to resolve the authentication issue. There are three ways by which you can restart the device:

  • Unplug the power switch: All you need to do is just to disconnect the power cable of your router. Wait for some time, and then connect it again. Now try connecting your smartphone; the network connection will be restored.
  • Turn the power button on and then turn it on: In case of wall-mounted routers, it’s difficult to unplug them or disconnect the power cable. So, you have an alternative option of using the power button. Turn the router off by using the power button. Wait for a few minutes and then turn it on. Most probably, your internet connection will get restored.
  • Use the warm reload option: You can restart the router by using the warm reload feature. In most cases, it will help you get rid of the error.
  • Check the allowed network users: Sometimes, your device fails to connect to a network because the maximum number of devices are already connected to it. You can check the settings of the router and change the number of allowed devices. After that, try to reconnect to the device.
