iwlwifi error popping up every few minutes in Kubuntu 23.10 using Intel AX210 card

[Jess Ferments]

I just installed Kubuntu 23.10 (using latest default kernel) on a new desktop PC I built, which uses an AX210NGW DTK M.2 wifi/bluetooth card. Here is output from lspci -v:

Wifi error popping up every few minutes in Kubuntu
I just installed Kubuntu 23.10 on a new desktop PC I built, which uses an AX210NGW DTK M.2 wifi card:

The internet seems to be somewhat working, but at least once a minute I have two "Network Management" error notifications that pop up in KDE that say "Connection Wired Connection 3 deactivated" and "Wired Interface e2x52e8ae7d39d1: IP configuration was unavailable".

I checked the logs in /var/log/dmesg and saw that there were a ton of iwlwifi error messages in there that look like this:

If it is helpful, I have output from "trace-cmd record -e iwlwifi -e mac80211 -e cfg80211 -e iwlwifi_msg" from when the error is occuring. If there are any other things that would help debugging this, I am happy to provide more info.

[AceLan Kao (acelankao)]

@Jess,

Yes, that would be helpful if you can help to collect the dynamic debug log by the trace-cmd.

There is no update for the iwlwifi firmware(-83) you are using now, but it might worth of trying to upgrade the firmware version to -84.
You can download the latest firmware from the linux-firmware git tree[1], but please remember that only copy the files you need. That help us to narrow down the required firmware.
In this case you probably only need iwlwifi-ty-a0-gf-a0-84.ucode, you can check your boot dmesg to see which firmware is loaded.
You can upload the boot dmesg here if you are not sure which firmware you are using.

[Jess Ferments (jferments)]

For some reason, Launchpad will not let me upload the trace.dat file from trace-cmd.

As far as updating firmware for iwlwifi, do you have any guidance for how to upgrade firmware to -84 correctly. I am happy to try to see if it fixes the problem, but I am not familiar with the correct process for updating a firmware module out of standard apt tree and don't want to accidentally break something.

[Jess Ferments (jferments)]

I just went ahead last night and updated to Ubuntu 24.04 with `do-release-upgrade -d` and it seems that this most of the iwlwifi errors are no longer popping up with the 6.8 kernel. Specifically, I am no longer getting the "Microcode SW error detected." and "api flags index 2 larger than supported by driver"

The only error I'm still getting for iwlwifi with 6.8 kernel is "WRT: Invalid buffer destination"

[AceLan Kao (acelankao)]

@Jess,

Does the "iwlwifi 0000:e4:00.0: WRT: Invalid buffer destination" error affect the wifi stability?
Could you provde a dmesg log after you upgraded to 24.04?

BTW, could you also check your wifi AP(router), try rebooting it or check if there is a new firmware for it, thanks.
