So we will find out together what to do and where to look to solve this problem of Wifi authentication. We will see at initially what you have to do on the Samsung Galaxy Grand Plus.

What to do when the Samsung Galaxy Grand Plus has an authentication problem on the Wifi network
Forget the Wifi network on your Samsung Galaxy Grand Plus
If perhaps the Wi-Fi network to which you desire to connect has been changed since your last authentication, your Samsung Galaxy Grand Plus may display the message: Authentication or authentication error . If perhaps the problem comes from there, the solution is straightforward. Simply forget about the Wifi network in your Samsung Galaxy Grand Plus. To do this, go to the settings of the Wifi network and keep pressed on the network in question. You will after that have the option to choose the option: Forget this network . Once it’s carried out, you can try again to connect to the Wifi network. In the event that the problem is not solved, go to the next step.
Press the box button
Whether your box is Orange, Bouygues Telecom, SFR or Numéricable, it may happen to have a problem of authentication Wifi on the Samsung Galaxy Grand Plus because the box is not in Synchronization mode . If you wish to activate the synchronization mode of your box, it can be incredibly simple. You should find a synchronization button to press. When ever this is carried out, a light will normally start blinking. Youre able to after that try to reconnect to the Wifi network with your Samsung Galaxy Grand Plus. If perhaps it still doesn’t function, go to the next trick.
Retype Security password
Sometimes the authentication problem comes from the method you type the Wifi network password. In truth, it can be sometimes subtle to type a password Wifi on its Samsung Galaxy Grand Plus. 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 several computer problems, the solution is at times incredibly simple. In truth, 80% of the computer problems are solved by restarting the machine. We therefore recommend you to restart your box and your Samsung Galaxy Grand Plus. Then try to reconnect with your Samsung Galaxy Grand Plus.
Check box settings
If perhaps non-e of the previous answers did function, the problem may perhaps 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 check whenever the system of key is in WPA / WPA2 . If perhaps this is not the case, choose this option. Then try to connect your Samsung Galaxy Grand Plus again to Wifi. If perhaps the authentication problem persists, we recommend that you contact your service provider or a telephone retail store.
