Do you need a compatible WIFI Driver for Imessage/facetime to work?

Almost the same setup, trying to get imessage/facetime to work. imessage logs me in then signs me out 2 seconds later with no error message, facetime runs the animation and doesn't sign in.

But I have no WIFI Compatible drivers nor a dongle. Only Ethernet. In chris's guide, this is said to cause issues. So do I need to get a dongle?
