I have the same problem (Windows 7 - up to date and Parallels Version 11.1.1 running the latest build (32312) on OS X 10.11.2) and it is really annoying. I use USB to connect my Ethernet to the VM and every time I start the VM I have to unplug and plug the USB. When will this get fixed? This is really poor implementation by Parallels and if it carries on it will encourage me to switch to VMware.
Hey, I would like to let you know that we have already involved our Development in this case and they are currently working on the resolution.
