Hi all,
I have an Acer Swift 3 notebook with Intel WiFi 6 AX201 adapter. It works well for almost 2 years with only 1 exception - sometimes WiFi connection becomes ve-e-e-ery slow. It happens rarely and unpredictably.
I saw topics about similar problems on different forums but all of them was about persistent slowness and were resolved by installation of firmware package (This package is installed in my system from the very beginning). I haven't noticed anything in logs until recent event so I haven't posted this problem before. But finally I was able to catch some simptomps in dmesg - see log below. But I have no idea what to do with it now. So, my questions are:
1) should I report it somewhere? (as a bug for example)
2) what kind of information should I collect next time when it happens?
3) have you any idea how to recover from this situation without PC reboot? - unfortunately now this is the only method I found to get back normal connection speed.
I understand that it my case some error happens that leads to the adapter restart as a recovery action. So, adapter is restarted, but it appears firmware isn't loaded after it and it remains slow. Are there any way to load fw manually or it is possible only during boot sequence?
