Steamdeck Dock NIC issue [solved]

Recently (as in: Mid January), there was an update to the SteamdeckOS and the Dockingstation firmware. Last Weekend I installed both of those and since then I am having probably NIC related issues.

Namely, the NIC in the dockingstation refuses to participate in more than DHCP.

Dock and USB-NIC plugged into said dock, both up, all is well:

Dock is up, USB-NIC down, DNS is dead:

3_1
3_11280×800 158 KB

DHCP-leases:

Does not matter where I plug the Dock into, it will not do DNS. IPv4 (and v6) is fine though.

Figured it out:
I seem to have set a DNS that was unreachable as default, which KDE helpfully did not show anywhere.

Note to self: Learn the ip command!
