From time to time, the Samsung Galaxy A21S displays the Authentication Problem message when you try to connect to a Wi-Fi network. This kind of error message can potentially be caused by several places. So, so that you may connect properly to the Wifi network with your Samsung Galaxy A21S, we decided to write this guide. So we will see together what to do and where to look to resolve this problem of Wifi authentication. We will see at 1st what you must do on the Samsung Galaxy A21S. At last, we will see what it is actually important to do and check on your Wifi box.
What to do when the Samsung Galaxy A21S has an authentication problem on the Wifi network
Forget the Wifi network on your Samsung Galaxy A21S
If perhaps the Wi-Fi network to which you desire to connect has been changed since your last authentication, your Samsung Galaxy A21S may display the text message: Authentication or authentication error . If perhaps the trouble comes from there, the solution is quite easy. Just forget about the Wifi network in your Samsung Galaxy A21S. To get this done, go to the settings of the Wifi network and keep pressed on the network in question. You will then have the option to select the option: Forget this network . When it is done, you may try again to connect to the Wifi network. If the trouble is not resolved, go to the next step.
Press the box button
Whether your box is Orange, Bouygues Telecom, SFR or Numéricable, it might happen to have a trouble of authentication Wifi on the Samsung Galaxy A21S because the box is not in Synchronization mode . If you would like to activate the synchronization mode of your box, it is actually incredibly basic. You should find a synchronization button to press. When this is done, a light will normally start blinking. You can actually then try to reconnect to the Wifi network with your Samsung Galaxy A21S. If perhaps it still doesn’t work, go to the next trick.
Retype Security password
From time to time the authentication problem originates from the way you type the Wifi network password. Indeed, it is actually sometimes subtle to type a password Wifi on its Samsung Galaxy A21S. We therefore advise you to try all the following possibilities:
- Type the code without spaces or hyphens
- Type the password in uppercase
- Type the password in lowercase
Restart your box
As in many laptop problems, the solution is at times incredibly simple. Indeed, 80% of the laptop problems are solved by restarting the machine. We therefore advise you to restart your box and your Samsung Galaxy A21S. After that try to reconnect with your Samsung Galaxy A21S.
Check box settings
If perhaps none of the prior answers did work, the problem could be found to be on the box of your provider. It will therefore be important to go in the parameters of the box and to test in the event that the system of key is in WPA / WPA2 . If perhaps this is not the case, select this option. After that try to connect your Samsung Galaxy A21S again to Wifi. If perhaps the authentication trouble carries on, we suggest that you contact your service provider or a telephone store.
