Description Mikael Setterberg 2024-02-07 13:30:28 UTC

Hardware: ASUS ROG Strix B550-F, AMD Ryzen 5700G, GC-WIFI7 rev1.0
Dist: Ubuntu 23.10
Kernel: 6.8.0-rc3-wt-ath+
Firmware: latest from git.kernel.org at the time of filing the bug

Driver loads and the card works. It can connect to 5Ghz and 2.4Ghz networks. However, it is not possible to connect to 6GHz only-networks. The computer also has an AX210 card installed that can see and connect to the 6GHZ-only. The access point is a Ubiquiti U7 Pro. Is the region not identified? The region should be set to Sweden I would presume (same as for the AX210 card), but iw returns the information below.

Thanks,
Mikael

Hello.
I applied this patch https://patchwork.kernel.org/project/linux-wireless/list/?series=920685 and it fixes issue but in firmware quiet incorrect frequencies, it looks like similar but another by some reason - in general you will get this issue https://bugzilla.kernel.org/show_bug.cgi?id=219522



Also by some reason https://patchwork.kernel.org/project/linux-wireless/list/?series=920685 this patch deferred 6 times but this patch really solve this issue and at least works



Here 6.12.6 kernel built with this patch https://github.com/serhii-nakon/new_debian_linux (if you want you can change environment to Ubuntu and use own config - in general pre-built release should works in Ubuntu I think) - I re-based it manually and I not C developer so something can be wrong but I already use this patch 1 week and at least no crashes and it  changes region and unblock and block frequencies (exclude issue related with firmware regdb)

I really waiting when those series of patches will be merged - and really don't understand why it not merged more then half year and at the same time everyone report that they can not use 5GHz and 6GHz properly
