Ethernet deactivated - IP configuration was unavailable

So Google Fiber is down and this may have exposed an oddity. I use wired networking generally but with google fiber being down none of the endeavoros installs are able to bring up their network interfaces except WiFi. Plasma networking reports that the IP configuration is unavailable and deactivates the interface on every machine. WiFi interfaces are mostly working.
The odd thing is that booting into Windows on the exact same machines, the Ethernet stuff works just fine. I cannot understand what’s misfiring and hoped someone might have some ideas. I saw this also for booting endeavoros from a thumb drive, also for cachy and gadura

Sorry for gratuitous typos - having to post from phone and I’m not good at that
