Buggy hotspot on XA2 / Windows 10

Two intermittent problems:

  1. Hotspot fails, not restored by Utilities. Laptop can connect to phone but no internet connection is created. Laptop doesn’t show “Setting up connection” dialog. Requires phone reboot.
  2. Hotspot working fine but turned off when not needed. Suddenly, data doesn’t work. Also requires phone reboot IIRC.

#1 is more common than #2, maybe 1 in 3 hotspot sessions. unless repeatedly turning hotspot on and off.
