So we will see together what to do and where to look to solve this problem of Wifi authentication. We will see at first what you must do on the Sony Xperia Z4.

How to proceed when the Sony Xperia Z4 has an authentication problem on the Wifi network
Forget the Wifi network on your Sony Xperia Z4
If perhaps the Wi-Fi network to which you desire to connect has been changed since your last authentication, your Sony Xperia Z4 may display the text message: Authentication or authentication error . If perhaps the problem comes from there, the answer is very simple. Just forget about the Wifi network in your Sony Xperia Z4. To accomplish this, 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 . When it is done, you can try again to connect to the Wifi network. In the event that the problem is not fixed, go to the next section.
Press the box button
Whether your box is Orange, Bouygues Telecom, SFR or Numéricable, it may happen to have a problem of authentication Wifi on the Sony Xperia Z4 because the box is not in Synchronization mode . If you want to activate the synchronization mode of your box, it truly is very simple. You should find a synchronization button to press. When ever this is done, a light will normally start blinking. You can after that try to reconnect to the Wifi network with your Sony Xperia Z4. If perhaps it still does not work, go to the next trick.
Retype Security password
Sometimes the authentication problem comes from the method you type the Wifi network password. In truth, it truly is sometimes subtle to type a password Wifi on its Sony Xperia Z4. 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 computer problems, the solution is occasionally very simple. In truth, 80% of the computer problems are solved by restarting the machine. We therefore advise you to restart your box and your Sony Xperia Z4. Then try to reconnect with your Sony Xperia Z4.
Check box settings
If perhaps non-e of the previous answers did work, the problem might be found to be on the box of your provider. It will therefore be required 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 circumstance, choose this option. Then try to connect your Sony Xperia Z4 again to Wifi. If perhaps the authentication problem persists, we recommend that you contact your service provider or a telephone store.
