So, I had ping spikes and device lockups on my Mediatek card, so after some fruitless efforts I just bought an Intel AX210 instead. It seems like it’s been working fine, but as of this week it started showing ping spikes and disconnects also, as well as issues with the device itself disappearing and then coming back.
I looked in the log and found this:
[ 5217.241411] iwlwifi 0000:01:00.0: Queue 2 is stuck 61887 61934
[ 5217.242294] iwlwifi 0000:01:00.0: Microcode SW error detected. Restarting 0x0.

… and then lots and lots of debugging output as it restarts the device. For some ridiculous reason, this forum won’t let me just upload the whole log, but some selected lines to give the flavor of what is happening:

And so on. As it’s doing any particular reset, obviously the network is unusable, and it enters into a user-visible flaky state for sometimes a pretty extended length of time.
The weird thing is that when looking back in kernel logs, I see that this has been happening the entire time since I installed the AX210 (periodically resetting the device because of a microcode error), but it seems in my subjective feeling like only recently it’s gotten bad enough that it was visible to me in the form of network flakiness. Sometimes it’ll go days without happening, and then sometimes it’ll start happening several times a minute and take down stuff I’m trying to do with the network or mean that the device isn’t even visible while it’s trying to get itself back going again.
It doesn’t seem especially correlated with kernel version, it seems like it just happens intermittently.
