Have you experienced connecting to a network only to receive a WiFi authentication error? If you have, don’t panic. It happens even if you have connected to such a network before. This problem isn’t necessarily serious, and in most cases, it can be easily fixed.
Why does authentication error happen?
The authentication error occurs when your device cannot successfully connect to a WiFi network even if you’re using the correct password. Under normal circumstances, your phone will automatically connect to the network if you have connected to such network before. You may encounter issues if you have an unstable signal, which you can improve the signal using cell phone signal boosters.
If you have accidentally enabled the Airplane mode, then your phone will not connect to any network. But sometimes, the problem is more than that. The following are some of the common reasons why you get a WiFi authentication error:
- Recent device update
- Router malfunction
- Unstable network connection
- Number of users that can use the network are limited
There are simple methods of fixing the authentication problem. The right solution depends on what caused the error to occur. The following are some of the common solutions which you can easily try.
Method 1: Forget the Network
The most common solution for authentication error is to reset the WiFi connection. You can do this by forgetting the network (the one you’re having problems connecting with) before you try connecting again. Here are the steps to do it.
Go to WiFi option in Settings
Go to Settings and look for Wireless & Networks. Some smartphones instead have Connections. Tap this and go to the WiFi option.
Find the network you’re having issues with
Once you click the WiFi option, you will see a list of nearby WiFi networks, including the ones you’ve already connected to before. Tap on the network you’re having issues connecting with.
When you choose the network, you will see a Forget network option. Tap this to reset the settings of the network selected. Once reset, try connecting to the network. You will be asked for the authentication password. Just type in the password and connect.
Method 2: Change the Wireless Network from DHCP to Static
Go to WiFi option in Settings
Go to Settings and open Wireless & Networks. Sometimes, this is labelled as Connections. Then just tap on WiFi.
Tap the network which you want to connect
There will be a list of the nearby WiFi networks. Just choose and press the network you’re having issues with (or the one you want to connect).
Modify the network
When you press the network, you will either see a Modify or Manage network option. Just tap on it.
Change the network to Static
In the WiFi setting, you’ll see an Advanced Settings. Choose this option and look for the IP Settings. From there, change the IP from DHCP to Static. Finally, enter the IP address (the one found at the back of the router) in the field. Save the settings, then reconnect.
Method 3: Reset Factory Setting
If the first 2 methods fail, or if your phone suffers from other random errors aside from authentication error, then your phone might have software issues. This also happens when you have installed firmware update, custom ROM or new application.
The best way to solve software issues is to reset your phone to factory settings. Just make sure that you’ve backed up your data. The best way to do this is to backup your phone first to the cloud. Once you have done this, you can then reset your device settings. Just follow the steps below.
Go to Backup & Reset
Go to Settings and then just scroll down to find the Backup & Reset option. Tap it to open.
Turn on Automatic Restore
You will see the Automatic Restore option. If it’s not turned on, make sure that you turn it on.
Reset Factory Data
Find the Factory Data Reset option and tap on it. Then tap the Reset Phone button to confirm the action. The process will take a few minutes. This will boot your phone’s system. If the problem is indeed due to software issues, then you can connect to the network.
Method 4: Restart the Router
If the first 3 methods didn’t work, the issue might be due to the router itself. Restarting the router might do the trick and restore the internet connection. There are 3 ways to restart your router, depending on the type of router you’re using. They are as follows:
Disconnect the power cable
For regular routers, the best and common way to restart it is to disconnect the power cable. Doing this will turn the router off. Wait for a few minutes before reconnecting the power cable and turning on the router again.
Restart using the power button or warm reboot
However, if you are using a wall-mounted router, then there’s another way of restarting it. Since it’s hard to access disconnect the power cable, you can instead push the power button to turn the router off. You can also use the warm reboot to automatically reset the connection.
Adjust the allowed connections
If there is an internet connection but you can’t still connect, it may be because many users are already connected to the router, and you have reached the maximum allowed connections. Just simply adjust the maximum number and restart the router.
