From time to time, the Sony Xperia T displays the Authentication Problem message when you try to connect to a Wi-Fi network. This sort of error message can possibly come from a lot of places. So, so that you can actually connect properly to the Wifi network with your Sony Xperia T, we decided to write this guide. So we will discover together what to do and where to look to solve this problem of Wifi authentication. We will see at 1st what you need to do on the Sony Xperia T. At last, we will see what it is actually important to do and check on your Wifi box.
What to do when the Sony Xperia T has an authentication problem on the Wifi network
Forget the Wifi network on your Sony Xperia T
If perhaps the Wi-Fi network to which you wish to connect has been changed since your last authentication, your Sony Xperia T may display the text: Authentication or authentication error . If perhaps the issue comes from there, the answer is fairly simple. Just forget about the Wifi network in your Sony Xperia T. To achieve 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 completed, you can actually try again to connect to the Wifi network. If perhaps 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 Sony Xperia T because the box is not in Synchronization mode . If you want to activate the synchronization mode of your box, it is actually very simple. You should find a synchronization button to press. When ever this is completed, a light will normally start blinking. You may then try to reconnect to the Wifi network with your Sony Xperia T. If perhaps it still will not work, go to the next trick.
Retype Security password
From time to time the authentication problem originates from the technique you type the Wifi network password. In fact, it is actually sometimes subtle to type a password Wifi on its Sony Xperia T. 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 from time to time 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 Sony Xperia T. After that try to reconnect with your Sony Xperia T.
Check box settings
If perhaps non-e of the previous answers did work, the problem could 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 cases where the system of key is in WPA / WPA2 . If perhaps this is not the case, choose this option. After that try to connect your Sony Xperia T again to Wifi. If perhaps the authentication issue continues, we suggest that you contact your service provider or a telephone retail store.
