My WiFi has been mostly working over the last few months, however there have been instances where the wifi adapter has failed and not been displayed in the UI. I didn’t properly log these occurrences so cannot remember if they were all boot time, waking from suspend, mid-usage, or a mix of those.
I reseated and re-cable managed the WiFi chip and its antennas a few weeks ago, and it has all been mostly working flawlessly since then.
I’m currently running kernel 6.4.4-200.fc38.x86_64 with the only recent change to kernel args being the addition of tpm_tis.interrupts=0 and the removal of rhgb quiet.
WiFi worked on my first 1-2 boots of this kernel, but on my third and subsequent boots I saw errors during bootup, or there would be no errors and the adapter would be found but a few seconds after login there would be a few seconds of system freeze followed by the adapter disappearing.
I used to be able to boot into kernel 6.4.4 following the errors but now it gets stuck there. I can boot with kernel 6.3.12, but the wifi adapter is not found
The wifi adapter is also absent when booting a fedora liveboot usb on kernel version 6.0.7.

Here is some dmesg output from the liveusb:

After rebooting out of the liveusb (into my internal drive) on kernel 6.4.4, the wifi adapter is found and working. EDIT 15 minutes later: there was a system freeze, i managed to move to another tty session and back after about 30 seconds, but wifi was no longer working. Another freeze occurred when I attempted to toggle wifi off and on again. I managed to move to another tty which printed loads of stack traces, I got a picture of what was currently on the screen.
After rebooting, the wifi adapter UI looked good, but freezes were occurring and wifi was not working. Here’s dmesg:

After rebooting again (same latest kernel), the wifi option from the UI has simply disappeared again, no freezes, but also no wifi.
I then booted a known good Windows drive which has had working wifi with this machine in the past, but this time it didn’t:
I then reseated the wifi card and booted linux, and wifi worked.
It would seem the issue is unrelated to the kernel version/args, and could be an intermittent hardware failure that is resolved by either leaving the system alone long enough to fully power down, or by disconnecting and reconnecting the wifi chip.
I see “HW failure” in some of the logs, does my Framework simply have a faulty WiFi chip? I have been experiencing these issue intermittently for months.
Please advise.
