Press the box button

Whether your box is Orange, Bouygues Telecom, SFR or Numéricable, it may happen to have a trouble of authentication Wifi on the Sony Xperia L2 because the box is not in Synchronization mode .

Retype Password

Restart your box

As in a great many pc problems, the solution is from time to time incredibly simple. In truth, 80% of the pc problems are solved by restarting the machine. We therefore advise you to restart your box and your Sony Xperia L2. Then try to reconnect with your Sony Xperia L2.

Check box settings

If non-e of the prior solutions did function, the problem may perhaps be found to be on the box of your provider. It will for that reason be important to go in the parameters of the box and to test whenever the system of key is in WPA / WPA2 . If this is not the case, choose this option. Then try to connect your Sony Xperia L2 again to Wifi. If the authentication trouble continues, we suggest that you contact your service provider or a telephone retail store.
