Problem:
Some Intranet or Ethernet connections with Windows 10 will fail to connect to an iPhone Personal Hotspot. The connection cycles on and off. Connecting with a USB cable works fine.
Diagnosis:
Windows 10 has trouble finalizing the connection if spaces are in the Hotspot name.
Solution:
Remove any spaces from your iPhone name. For example, change "Doug's iPhone" to Doug's_iPhone".
