What to do when the Mi 9T has an authentication problem on the Wifi network

Forget the Wifi network on your Mi 9T

In cases where the Wi-Fi network to which you want to connect has been changed since your last authentication, your Mi 9T may display the text: Authentication or authentication error . In cases where the problem comes from there, the answer is quite easy. Simply forget about the Wifi network in your Mi 9T. 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’s completed, you may try again to connect to the Wifi network. If perhaps the problem is not fixed, go to the next step.

Press the box button

Whether your box is Orange, Bouygues Telecom, SFR or Numéricable, it might happen to have a problem of authentication Wifi on the Mi 9T because the box is not in Synchronization mode . If you need to activate the synchronization mode of your box, it is actually incredibly basic. You should find a synchronization button to press. When this is completed, a light will most of the time start blinking. You may then try to reconnect to the Wifi network with your Mi 9T. In cases where it still will not work, go to the next trick.

Retype Password

Oftentimes the authentication problem comes from the way you type the Wifi network password. Indeed, it is actually sometimes subtle to type a password Wifi on its Mi 9T. 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 lots of laptop problems, the solution is occasionally incredibly simple. Indeed, 80% of the laptop problems are solved by restarting the machine. We therefore advise you to restart your box and your Mi 9T. Then try to reconnect with your Mi 9T.

Check box settings

In cases where 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 necessary to go in the parameters of the box and to test in cases where the system of key is in WPA / WPA2 . In cases where this is not the circumstance, choose this option. Then try to connect your Mi 9T again to Wifi. In cases where the authentication problem continues, we highly recommend that you contact your service provider or a telephone store.
