Hi, I have a Wifi and my MacBook and iPhone both connects just fine. When I connect my iPhone to my Mac using USB, the iPhone loses WiFi and reverts back to 4G. After this the iPhone can't even reach the internet over the 4G connection. I removed the iPhone USB network service from the OSX network settings, but that didn't help. I also tried turning WiFi off and on again on the iPhone with no effect. Removing the USB cable restores WiFi, and turning WiFi off also shows that 4G now works as expected. I tried another iPhone, and this does not happen on that device so it is connect to a specific device. I've never seen this before. Anyone experienced the same thing ? --- Post Merged, Apr 18, 2017 --- Now I tried to Reset Network Settings with no success. I also tried shutting down iTunes, Xcode and the VPN connection I had running on the mac. --- Post Merged, Apr 18, 2017 --- Finally tried tro reboot Mac with no effect.
