Well, as the post states I have a Ethernet port showing unknown after a reboot. Been running for a few years fine. Tried rebooting and restarting the network manager but I’m a loss here. Hardware is a nuc11 with an i7 and 2.5 gbe nic
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo

inet6 ::1/128 scope host noprefixroute
valid_lft forever preferred_lft foreverNZB Geek API: HMiN8DoCH6sEeqj7q7UE0Mtg4ewuXrZ6

Update: I have found the NIC, it’s showing as “unclaimed”.
It does not show up in the network manager (Fedora). Ifconfig also only shows loopback and wifi.
I did now find it at the bottom of the command so that’s something at least.

Try booting from a live disk. If it works there, it’s probably an update or config change that’s causing problems.
Booting into an old kernel fixed it
