BE201 WiFi card not working under Linux (latest kernel 6.14.4, Fedora 42)

[hcording]

There is an issue with the BE201 WiFi card when running Linux.

The drivers were added to the kernel by Intel and are being loaded properly, lspci shows the card.

However, dmesg says:

"RFIm is deactivated, reason = 4"

and

"BIOS contains WGDS but no WRDS"

and it's not possible to connect to any networks. Bluetooth is functional though.

Please find more details in the corresponding Bugzilla post: https://bugzilla.kernel.org/show_bug.cgi?id=220085

I have done additional research and I think the issue relates to the regulatory domain settings enforced by LAR.

iw reg get:
global
country DE: DFS-ETSI
        ...

phy#0 (self-managed)
country 00: DFS-UNSET
(2412 - 2413 @ 1), (6, 22), (N/A)

Furthermore, `iw phy0 channels` shows that all channels are disabled.

Since lar_disable doesn't work since Kernel 5.4, I'm unsure how to proceed.

Happy to provide more information. Logs attached.

Thanks!

Hello,

Not that there was much hope, but I reached out to Asus just in case. I received the answer below. It's french but basically says "not our problem, you linux freaks can fend for yourselves lol"

I have a Zenbook Duo 2025, same wifi card AFAICS (BE201 PCI-ID 8086:7740) 

Distro: Linux from Scratch

Kernel 6.15.3

I get an "input/output error" attempting to modprobe the iwlmld module on a freshly build 6.15.3 kernel. udev doesn't want to bind the card either, kernel logs don't even report attempting to load the module although that might be because it doesn't get far enough in loading the module to actually output it's attempting to load. 

I can recompile kernels with patches if anyone wants me to try.

Hello! 

I was wondering if you found a solution to this? I have been facing the same issue on the Zephyrus G16.

Thank you for your help!

Please look at the bugzilla link for the bug report, this issue has been fixed and will be merged into one of the future kernels. The patches, if you'd like to play with recompiling the current kernel while applying them, are also present there.
