  1. again under Hyper-V settings, try adding a Legacy Network Adapter instead of a standard one.


You still might have to wait for a network configuration process to finish, but generally speaking, this has worked for me (and - by the way - it's a Linux kernel bug for which there is a patch somewhere if you search for it long enough :) )...
