network and USB2 inaccessible on new install

Yes, is unreachable with the “From icmp_seq=1 Destination Host Unreachable” error.

From a live CD (Mint/KDE) I get the old “connect: Network is unreachable” error as expected. In pop-ups, and via the Notifications widget, I see a string of notifications like “Connection ‘Wired connection 1’ deactivated.” and one “IP configuration was unavailable”.
