Hey guys, not sure if this is a good place for this, so let me know if this post would be better suited elsewhere.

Also, I know, I know, make sure your device is compatible with linux-- but when Newegg said “compatible with ubuntu” I naively thought that put me in the clear. Now I know better, and I’ll be checking the wifi card compatibility. Anways, here’s the situation:

I’m running debian bookworm on an MSI Modern notebook. On every distro I’ve tried, I’ve had an issue where my wifi acts extremely inconsistently. For a while upon a fresh install of any OS, it works wihout issue. Then, after a few weeks, and especially after too much uptime, one or more of a few different issues will start happening, seemingly at random:

  • The network manager will suddenly fail to detect that there is any wifi adapter installed at all. (For some reason, this can be fixed by discharging the motherboard battery and restarting).
  • Wifi networks will be visible, but will not be able to authenticate, even with correct credentials. This can occur even with unsecured wifi networks. (The time before last that this happened, it randomly fixed itself).

After about two weeks of using my system after it magically fixed itself, the wifi adapter stopped being recognized, so I did the motherboard discharge and reboot, and when I could access the wifi settings again, the authentication issue had reappeared. After several days of use, it hasn’t fixed itself. So now I’m posting here, after many months of being unable to figure out a good solution.

I’ve tried and failed to troubleshoot this problem over many hours. Some related issues/factors that might help explain what the problem is:

  • After some research, I’ve noted that other people have had problems with the wifi card in this laptop (MEDIATEK MT7921K (RZ608) Wi-Fi 6E 80MHz).
  • Despite debian supporting secure boot, if I ever try to enable secure boot, I am given a “secure boot violation”.

If anyone could help me get pointed in the right direction, show me what I could potentially reinstall or reset without having to reinstall my OS every time this happens, I would super appreciate it. And of course if I didn’t include some spec please let me know and I’ll update this post with the necessary spec.
