What to do when the Hisense L675 has an authentication problem on the Wifi network

Forget the Wifi network on your Hisense L675

In the event that the Wi-Fi network to which you want to connect has been changed since your last authentication, your Hisense L675 may display the text message: Authentication or authentication error . In the event that the issue comes from there, the answer is straightforward. Just forget about the Wifi network in your Hisense L675. To do this, go to the settings of the Wifi network and keep pressed on the network in question. You will then have the option to choose the option: Forget this network . When it is done, you may try again to connect to the Wifi network. In the event that the issue 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 issue of authentication Wifi on the Hisense L675 because the box is not in Synchronization mode . If you wish to activate the synchronization mode of your box, it is very basic. You should find a synchronization button to press. When ever this is done, a light will most of the time start blinking. You may then try to reconnect to the Wifi network with your Hisense L675. In the event that it still will not work, go to the next trick.

Retype Security password

Oftentimes the authentication problem originates from the way you type the Wifi network password. In fact, it is sometimes subtle to type a password Wifi on its Hisense L675. 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 sometimes very simple. In fact, 80% of the laptop problems are solved by restarting the machine. We therefore recommend you to restart your box and your Hisense L675. After that try to reconnect with your Hisense L675.

Check box settings

In the event that non-e of the previous answers did work, the problem may 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 . In the event that this is not the case, choose this option. After that try to connect your Hisense L675 again to Wifi. In the event that the authentication issue continues, we advise that you contact your service provider or a telephone retail store.
