No matter what I seem to try I cannot get the Personal Hotspot feature to work. Call Apple last week, they finally told me to do a software restore, I did restore to iOS 10.3.2 yesterday. Cannot connect via Wifi, Bluetooth or USB!! Call Apple today, spoke with Senior level tech, he's stumped and reaching out to their engineers. I've confirmed with AT&T that my plan allow for hotspot teathering. I've pulled my SIM out of iPhone, inserted it into a new Google Pixel phone and hotspot works great from Pixel phone. Put it back into iPhone and cannot get hotspot to work in any fashion. WTH!! ?? So damn frustrating!! Client devices see the wifi / bluetooth hotspots, seem to connect to the wireless network layer but do not get IP address and therefore end up with self-assigned 169.... address. I've tried assigning statically the 172.20.10.0 network but still nothing. Cannot connect via USB either. It shows up in the Windows 10 network settings window but has a red X. Does anyone know how to fix this??
