WIFI adaptor stopped working suddenly.

mr.monsterkoala · 2025-01-19 15:00:07

Hi, I am using arch for more than 2 years and last week my wifi adapter stopped working suddenly, I thought maybe it was due to the new update so I updated again this week and it still doesn't work. My motherboard, B650 Aorus Elite AX V2 comes with wifi modem and I have been using that one since the beginning, I never needed any drivers for it on arch but it just stopped working suddenly. I tried to check the arch wiki and see if my wifi driver is being loaded using lspci -k but this is the output that I am getting, I guess the driver isn't being loaded as I don't see anything related to wireless network. If anyone can help troubleshooting, that will be very helpful, thank you.

What linux kernel do you have right now and what happens if you switch it over to LTS?

mr.monsterkoala · 2025-01-19 15:15:36

hello, I am using 6.12.10 and even if I switch to LTS I get same problem where the WIFI adapter isn't found by gnome.

Did you reboot your system in the process? Is this on a system with dual boot?

seth · 2025-01-19 16:21:26

From the board it's likely a Mediatek MT7921K that doesn't even show up in lspci.
If it's not a dual-boot system - 3rd link below. Mandatory. Disable it (it's NOT the BIOS setting!) and reboot windows and linux twice for voodo reasons. - try to completley power down the system (cut it from any external power supply) get a cup of coffee, boot it and see whether you device returned.

mr.monsterkoala · 2025-01-19 16:30:37

Thanks for the replies, it's not a dual boot system, I am just using arch only. I was using dual boot long time ago but currently there is no windows, the drive is formatted and is used as an HDD that's mounted on arch.

Arch Linux
