Yesterday, i switched on my computer and i don’t have internet (with ethernet)…i didn’t apply an updates about network…so i rollbacked with a snapshot (thank btrfs)…no effect. With ip link, i saw my card but “state down”. So i type “sudo ip link set enp3s0u2 up”, i saw state up and after 1 second down…i reboot on iso cachy same pb, on windows same pb…
I switch off my pc. i can’t reboot it : light orange blink : error memory.
I removed my memory cards, plug them again and everything works…
So be careful if you don’t have internet, check your memory card,…lol
