I have a Windows 10 laptop with an Intel AC 8265 WiFi card. I have loaded the latest driver (Ver 188.8.131.52).
When I enable the Windows 10 Mobile Hotspot feature, it shows 0 of 8 connections. I can connect to my laptop from both my iPhone and iPad, but in both cases the connection hangs with a "No Internet" status. In addition, the laptop does not show any connections to the hotspot.
