I want to share this as I saw another post detailing the same fault.
Since the end of June, my phone will not connect to WiFi. The only fix seems to be restarting the phone, which is a 50/50 gamble on whether it connects or not. Even then, the Wifi cuts back at out after 10 minutes. Most of the time the Wifi button is greyed out when it is clicked, and when it is not, it scans for networks and finds none.
I believe this is either a fault with the signal wire in the hinge or a fault of the latest update. I have tried all troubleshooting steps with no luck.
Has anyone else had this problem?
