Intel BE200 Microcode SW error detected

BlastChaser — Wed, 19 Feb 2025 06:48:59 GMT

Hi,

My network wifi card (Intel BE200) seems to crash every 5~10 minutes, resulting in frequent disconnections and very annoying user experience. I am trying to figure out what is going on, and I keep seeing "Microcode SW error detected" followed by a core dump from the iwlwifi module. Any help is appreciated! See attached logs.

I am running the latest microcode provided by the Arch repositories:

Feb 18 22:23:32 wirerider kernel: iwlwifi 0000:2e:00.0: loaded firmware version 94.62990553.0 gl-c0-fm-c0-94.ucode op_mode iwlmvm

Here is the coredump:

Hello BlastChaser,

Thank you for your patience. I have a few follow-up questions regarding the Microcode Software error you mentioned. Please provide answers to the following:

Could you let me know when the issue first started? Was the wireless connection functioning properly before this issue occurred?
Have you attempted to connect to a different access point to see if the issue persists?
Please try installing the latest stable version of the Linux Kernel from kernel.org. After installation, let me know the results.
Have you reached out to Nitrokey for further assistance regarding this issue?

Hi, sorry for the delayed reply. I did try your suggestions.

1) The error started sometime in the last month. I did not pay attention to say exactly when.

2) Yes with mixed results. I tried two access points at my home, both exhibited the problem. Then, a few days ago (after I started this post), I tried a third router in a different building and the problem no longer occurs.

3) I've installed latest via Arch repositories, this did not fix the issue. I also tried on LTS kernel as well. No change with these kernels.

4) Yes. They are unaware of any issues and unable to provide much assistance.

Thanks

Hello BlastChaser,

Thank you for getting back to me. Your response to question number 2 is quite interesting. Before we delve into that, could you let me know if the issue persisted after following my suggestion?

Moving forward, could you please provide the exact model of the two access points you have at home? Additionally, include the model of the one you used in a different building. From what I can tell, the issue might be related to your home router rather than the access points.

Best regards,

Dhanniel M.

No, the issue persisted across multiple access points.

Unfortunately I don't have the model numbers, because it was not my home and I am no longer staying there

Perhaps its not useful to keep debugging this issue. I will reply back if the issue returns.

Thanks for your time!
