I’m running Ubuntu 22.04 on my 12th gen with an AX210 wireless card.
Starting a few weeks ago, my network adapter would occasionally stop working and disappear. The only way to get it working again was by restarting my laptop. This seemed to occur when I physically moved my laptop away from my desk, but it wasn’t consistent so I wasn’t sure. I initially thought it was because my network adapter was getting confused when going from one wi-fi connection to another, but I tested it in a location with only 1 wi-fi network and had the same issue.
This past week, it’s gotten worse and everytime I move my laptop off my a flat surface, the network adapter goes out. When I restart my computer, about half the time it will also not be detected. I chased some software solutions, including turning off fast boot in BIOS, but did not have any consistent success.
At this point, I suspect it’s a hardware issue, but I want to check to rule out software problems if this is a known problem for anyone else. If it is a hardware issue, would appreciate any help in troubleshooting, as playing Russian roulette everytime I move my laptop has been incredibly stressful.
At first reboots would temporarily resolve the issue, but over time it got worse and my system would freeze during boot due to iwlwifi getting very upset with my WiFi card, and I would have to reseat the card on a semi-regular basis just to boot.
I’ve documented my troubleshooting steps here, which may help you resolve the problem or share with us the extent of it:
Yes, it disappears from lspci. I can reproduce the problem pretty easily, so when I run dmesg -w I can see the network adapter disconnect when I lift my laptop. I’m traveling, so trying to get a hold of a T5 screwdriver to tighten things up and hopefully resolve the problem…
