Press the box button

Retype Password

Check box settings
If perhaps none of the prior answers did function, the problem might be found to be on the box of your provider. It will consequently be required to go in the parameters of the box and to check in cases where the system of key is in WPA / WPA2 . If perhaps this is not the case, select this option. After that try to connect your Sony Xperia 5 IV again to Wifi. If perhaps the authentication trouble continues, we highly recommend that you contact your service provider or a telephone store.
