Few days ago I plugged my android (HTC1) phone to my Win7 machine which never had any network issues.
When I connected, I also made th following change:
Mobile Hotspot & tethering->USB network Setting->Internet pass through
Even when the phone is disconnected, from time to time, something (new) resets the DNS setting to my phone's IP address. I reset with ipconfig /renew
and it is fine for a while, but eventually flips back.
Update:
Ran wireshark on PC and it looks like the phone is sending DHCP ACKs and announcing itself as the router & DNS server etc.
This can't be a feature, How am I supposed to stop it?
