Description:

Upgrading package linux-firmware from 20211027.1d00989-1 to 20211216.f682ecb-1 results in Intel Corporation Wireless-AC 9260 (rev 29) not being able to connect to 5G wifi. The device can see 5G wifi access point but attempts to connect results in authentication error. Downgrading the linux-firmware package will cause it to work again. No issues connecting to 2G wifi.

When using the upgraded linux-firmware (and not functional) package, I see the following entry in dmesg:
[ 3.830214] iwlwifi 0000:3b:00.0: loaded firmware version 46.5e069cbd.0 9260-th-b0-jf-b0-46.ucode op_mode iwlmvm

But when using the downgraded (and functional) linux-firmware package, I see the following entry in dmesg:
[ 3.767025] iwlwifi 0000:3b:00.0: loaded firmware version 46.6b541b68.0 9260-th-b0-jf-b0-46.ucode op_mode iwlmvm

On a Thinkpad W520 with an

03:00.0 Network controller [0280]: Intel Corporation Centrino Ultimate-N 6300 [8086:4238] (rev 3e)

and linux 5.16.arch1-1, I see a similar problem:

Rebuilding linux-firmware with

_commit=13dca280f76009ba2c5f25408543a1aaaa062c25
pkgver=20220111.13dca28

and installing the resulting package, then unloading and reloading the iwlwifi module solved the issue for me:

(Disregard the rfkill stuff - I had tested on the laptop both with enabled and disabled WLAN/WWAN hardware switch, and the switch happened to be in the off position when I reloaded the iwlwifi module)

Please try latest firmware package from testing.
Comment by Pascal Ernster (hardfalcon) - Wednesday, 19 January 2022, 12:59 GMT
tpowa: Thanks, this solved the issue I mentioned for me. Can't say anything about Intel AC 9260 though since I don't own that hardware.

Has this issue really been solved by the current firmware? Because I still have an issue where after my laptop wakes up from sleep it can't see any 5Ghz networks. I have an Intel AC 9260. Has anyone experienced something similar?

Update on this, the latest released package, linux-firmware 20220209.6342082-1, seems to correct the issue.
