From time to time, the THL W200s displays the Authentication Problem message when ever you try to connect to a Wi-Fi network. This sort of error message can possibly result from several places. So, so that you can connect properly to the Wifi network with your THL W200s, we decided to produce this tuto. So we will observe together what to do and where to look to resolve this problem of Wifi authentication. We will see at first what you need to do on the THL W200s. Finally, we will see what it’s necessary to do and check on your Wifi box.

What to do when the THL W200s has an authentication problem on the Wifi network

Forget the Wifi network on your THL W200s

In the event that the Wi-Fi network to which you wish to connect has been changed since your last authentication, your THL W200s may display the text: Authentication or authentication error . In the event that the problem comes from there, the solution is quite simple. Just forget about the Wifi network in your THL W200s. To get this done, 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 is done, 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 possibly happen to have a problem of authentication Wifi on the THL W200s because the box is not in Synchronization mode . If you would like to activate the synchronization mode of your box, it’s very basic. You should find a synchronization button to press. When this is done, a light will normally start blinking. You can actually after that try to reconnect to the Wifi network with your THL W200s. In the event that it still does not function, go to the next trick.

Retype Password

From time to time the authentication problem comes from the way you type the Wifi network password. In truth, it’s sometimes subtle to type a password Wifi on its THL W200s. We for that reason 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 laptop problems, the solution is at times very simple. In truth, 80% of the laptop problems are solved by restarting the machine. We therefore recommend you to restart your box and your THL W200s. Then try to reconnect with your THL W200s.

Check box settings

In the event that none of the previous answers did function, the problem may perhaps be found to be on the box of your provider. It will for that reason be necessary to go in the parameters of the box and to check in the event that the system of key is in WPA / WPA2 . In the event that this is not the case, choose this option. Then try to connect your THL W200s again to Wifi. In the event that the authentication problem remains, we advise that you contact your service provider or a telephone retail store.
