For context read the https://forum.manjaro.org/t/manjaro-kde-intel-ax201-suddenly-stops-working/124653 Opening another thread since it didn’t solve the issue.
Comparing the logs when the wifi works and it doesn’t, I see there is this difference
working wifi
so the op_mode iwlmvm (argument?) might be the difference between working and not working. I have no clue what it means and how to change it, but when I start fresh the laptop I read it in dmesg.
Does anyone know what it means and how can I set it back if the wifi stops working again?
I searched a lot but could not find anything I could comprehend. Thanks!
Thanks @j8a
I will try to grab those info next time it gets stuck.
I already checked the rfkill and it wasn’t the issue. The wireless device is not present in ip a.
I also tried to reload the iwlwifi module with different parameters disable (802n and more I found in arch forums) but nothing.
The only log I saved from the last time is the dmesg. Following the logs, it seems it tries to load the ucode version 72. It doesn’t work. It fall back to version 71, loaded with op_mode iwlmvm and it works. After a while (check the delta in the timestamp) there is the infamous Microcode SW error detected. Restarting 0x0. and it tries to reload the ucode version 71 withoutop_mode iwlmvm. It then fails. Further down, the log is filled with retries of Loaded firmware version: 71.058653f6.0 QuZ-a0-hr-b0-71.ucode again without the op_mode iwlmvm.
I think that could solve the issue.
Right now I am trying to use another suggestion, that is disabling the 40mhz band. I read in intel forum that ax201 might have issue with that
and put “turn wifi on” on all (ac, battery, critical) “energy saving” KDE setting
I highly doubt ipv6 and network manager are at faults, since it works normally and then it just doesn’t start up. I will try this nonetheless if there is another crash.
I will try that and then just sell this laptop and buy another one
