Press the box button

Whether your box is Orange, Bouygues Telecom, SFR or Numéricable, it may possibly happen to have a problem of authentication Wifi on the Samsung Galaxy Note 9 because the box is not in Synchronization mode . If you need to activate the synchronization mode of your box, it can be very basic. You should find a synchronization button to press. When ever this is done, a light will normally start blinking.

Retype Security password

Occasionally the authentication problem originates from the way you type the Wifi network password. In fact, it can be sometimes subtle to type a password Wifi on its Samsung Galaxy Note 9. We consequently 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 pc problems, the solution is occasionally very simple. In fact, 80% of the pc problems are solved by restarting the machine. We therefore recommend you to restart your box and your Samsung Galaxy Note 9. After that try to reconnect with your Samsung Galaxy Note 9.

Check box settings

In cases where none of the prior solutions did work, the problem may be found to be on the box of your provider. It will consequently be necessary to go in the parameters of the box and to check if perhaps the system of key is in WPA / WPA2 . In cases where this is not the case, choose this option. After that try to connect your Samsung Galaxy Note 9 again to Wifi. In cases where the authentication problem persists, we suggest that you contact your service provider or a telephone retail store.
