AX200 Wifi frequently disconnects after upgrading to Debian 12

DanielH · ‎12-02-2024

Hello,

After recently upgrading to Debian 12 from Debian 11, my Wifi has been disconnecting frequently.

I am using an AX200 (lspci shows: "Network controller: Intel Corporation Wi-Fi 6 AX200 (rev 1a)") and running dmesg after a wifi disconnect shows the following error messages repeated dozens of times.

The specific queue that gets stuck and the values after "Queue X is stuck" vary between messages, but everything else appears to be the same.

In case it's helpful, I'm running Linux kernel 6.1.0-28-amd64 and the firmware versions for iwlwifi were obtained through Debian's non-free-firmware repo using apt. This is what I get running apt show firmware-iwlwifi:

To give a bit of additional context, I've been using my AX200 for years with no issue on Debian 10 and 11, but the problem started when I upgraded to Debian 12 about two months ago. The problem is also pretty sporadic, I can go days without any Wifi problems, but on some days it will constantly disconnect.

Any help will be appreciated.

Thank you,

Daniel

Sounds Like its an issue with Debian 12 since Debian 10 and 11 worked good with AX200. Can you update the Kernel ? I start a thread in Debian User Forums to get resolution on the wifi issues, System and Network Configuration is a good place to start.

I'd really prefer not to update the kernel since stability is the entire reason I run Debian in the first place. Debian is always a bit behind on software and kernel versions, but their team does a good job of ensuring that all the software available from their official repos works together without issue.

I can certainly switch to their unstable repos and install a newer kernel version, but I'd rather not do that for the only non-free piece of software I'm using (the iwlwifi drivers), especially if I'm not 100% sure upgrading the kernel will fix the issue. It definitely seems like there's some compatibility issue between the kernel and Intel's firmware, but it's strange that it ran fine on older versions of the kernel and I'd prefer to know which pieces aren't cooperating.

I'll certainly try asking on the Debian user forums too, but since Intel's drivers/firmware are proprietary, I'm doubtful they'd be much help.

Intel writes these drivers for specific Debian Kernels at a specific time. Debian kernels after this are suppose to keep these parts of the Kernels so that Wifi drivers will work with succeeding Kernels. I'm fairly certain that Debian forums is your best bet, Intel has already issued the drivers and is done as far as I can tell.

Okay, I've posted the issue on the Debian user forum a few days ago, but it seems like a lot of people are having similar issues and none of the suggestions seem to work. I've tried reverting to older firmware versions and have even upgraded my kernel to 6.11 which should fall under what is required for all Intel wireless adapters according to https://www.intel.com/content/www/us/en/support/articles/000005511/wireless.html. In fact my old kernel version should have been sufficient for the AX200.

I'm still getting the same issue.

It really seems like this has more to do with how Intel's firmware interfaces with the more modern versions of the linux kernel than anything specific to Debian. Especially since the error message is claiming it's a microcode error in the iwlwifi firmware.

Look at this post. Briefly try another Channel. There is free wifi channel scanners to download. Pick and use the strongest channel.
