Forget the Wifi network on your OnePlus 5T

If the Wi-Fi network to which you wish to connect has been changed since your last authentication, your OnePlus 5T may display the text: Authentication or authentication error . If the issue comes from there, the solution is quite simple. Just forget about the Wifi network in your OnePlus 5T. 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 carried out, you can actually try again to connect to the Wifi network. In the event that the issue is not resolved, 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 OnePlus 5T because the box is not in Synchronization mode . If you need to activate the synchronization mode of your box, it is very basic. You should find a synchronization button to press. When this is carried out, a light will most of the time start blinking. You’re able to after that try to reconnect to the Wifi network with your OnePlus 5T. If it still will not work, go to the next trick.

Retype Security password

Occasionally the authentication problem comes from the solution you type the Wifi network password. In fact, it is sometimes subtle to type a password Wifi on its OnePlus 5T. 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 a great many laptop problems, the solution is occasionally very simple. In fact, 80% of the laptop problems are solved by restarting the machine. We therefore advise you to restart your box and your OnePlus 5T. After that try to reconnect with your OnePlus 5T.

Check box settings

If none of the previous answers did work, the problem may perhaps 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 check if the system of key is in WPA / WPA2 . If this is not the case, choose this option. After that try to connect your OnePlus 5T again to Wifi. If the authentication issue carries on, we recommend that you contact your service provider or a telephone retail store.
