Alright, thank you so much so far!
I already followed this guide/thread when I was still trying to get my WiFi to work, I came back to it to try again when I gave up the idea of WiFi and tried to just get ethernet to work. But apparently the user had to put the VM in PV mode to get ethernet to work, but this last step I couldn’t do, because I can’t start Qubes in PV mode
I tried it with detached device too.
Thanks for this suggestion, hadn’t tried that so far! Unfortunately, the issue persists. I actually had to create the 04-ethernet-permissive.service in /lib/systemd/system/ instead of /etc/systemd/system because when I unmasked it, it got deleted. But after enabling the service in the /lib/ path it got created in /etc/ too.
Still No networking devices available in sys-net
Tried it with fedora as default of everything, too. PV mode is the only thing I can’t try…
