I have an Android X6 Plus, it was able to connect to the WiFi just fine before I did a factory reset on it. I've restarted the router, forgot the WiFi, put it on airplane mode and reset the phone once again. I really don't know what else to do. It starts to authenticate and stops. I've also tried to disable my tablet WiFi, trying to make sure that it wasn't being blocked by multiple WiFi connections and it still didn't work. If anyone has any suggestions, please let me know! (My WiFi security is WPA/WPA2 PSK)
For a week I was wasn't able to login to my work Wi-Fi with my android V10 phone. All I did was go to the settings then go to apps and then click on chrome and then you delete all updates. And bum problem fixed.
