Forget the Wifi network on your LG Optimus L9

In cases where the Wi-Fi network to which you wish to connect has been changed since your last authentication, your LG Optimus L9 may display the message: Authentication or authentication error .

When it’s carried out, you can actually try again to connect to the Wifi network. If perhaps the trouble is not solved, go to the next section.

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 LG Optimus L9 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 carried out, a light will normally start blinking. You can then try to reconnect to the Wifi network with your LG Optimus L9. In cases where it still does not function, go to the next trick.

Retype Security password

From time to time the authentication problem originates from the way you type the Wifi network security password. Indeed, it is actually sometimes subtle to type a security password Wifi on its LG Optimus L9. We for that reason advise you to try all the following possibilities:

  • Type the code without spaces or hyphens
  • Type the security password in uppercase
  • Type the security password in lowercase

Restart your box

As in lots of laptop problems, the solution is oftentimes incredibly simple. Indeed, 80% of the laptop problems are solved by restarting the machine. We therefore recommend you to restart your box and your LG Optimus L9. After that try to reconnect with your LG Optimus L9.

Check box settings

In cases where non-e of the prior solutions did function, the problem could possibly be found to be on the box of your provider. It will for that reason be required to go in the parameters of the box and to check in the event that 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 LG Optimus L9 again to Wifi. In cases where the authentication trouble persists, we highly recommend that you contact your service provider or a telephone store.
