AX210 6 GHz on Linux

[Artim]

For all I know, there shouldn't be a reason 6 GHz shouldn't be allowed in my country. I know it did work a couple of months ago, but it stopped working at some point. For all I know, the regulatory.db shouldn't prohibit it in my region, but then I have no idea how to read my local copy of it. Though if I look into this repo and read the db.txt, this is what it says for my country:

DFS-ETSI
(2400 - 2483.5 @ 40), (100 mW)
(5150 - 5250 @ 80), (200 mW), NO-OUTDOOR, AUTO-BW, wmmrule=ETSI
(5250 - 5350 @ 80), (100 mW), NO-OUTDOOR, DFS, AUTO-BW, wmmrule=ETSI
(5470 - 5725 @ 160), (500 mW), DFS, wmmrule=ETSI
# short range devices (ETSI EN 300 440-1)
(5725 - 5875 @ 80), (25 mW)
# WiFi 6E
(5945 - 6425 @ 320), (23), NO-OUTDOOR, wmmrule=ETSI
# 60 GHz band channels 1-4 (ETSI EN 302 567)
(57000 - 66000 @ 2160), (40)

I use the newest firmware fom https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/ and Kernel 6.14.2. Also, my Android phone has no issues sending 6 GHz either for all I can tell, another reason this shouldn't be an issue with regulations. The only "solution" I could find in this thread was this one, but I wouldn't call unplugging the antenna a solution. So how can I have my device see 6 GHz networks again?

@Artim I also find the "official" response disappointing.

If all the Intel folks are going to do is repost articles I already read (and which did not solve the problem), or insist that the problem must be solved by the "system manufacturer", then I don't know what the point of these forums is.

The questioning of whether 6 GHz is "legal" for use in one's region is especially silly.  Yes, because we obviously bought our AX210 add-in cards on the black market.  WTF.

Supposing there even were a "system manufacturer" willing to tackle the problem:  How would they do it?  Most likely by asking Intel for help, since it's Intel's hardware that appears to be misbehaving.

Anyway for actual troubleshooting, you might try any or all of the following distros:

1) Linux Mint 22.1

2) Fedora 42 Workstation

3) Fedora 42 KDE Plasma

With all of these, I have had 6 GHz WiFi work on my AX210, in both Live sessions and in full installs. 

I know these are not the distros you want to use permanently, but it doesn't require much investment of time or effort to give them a try.  If you can get 6 GHz WiFi working in a live session of any or all of these Linuxes, then you know your AX210 hardware does in fact work, at least under some OS's.  That should be helpful information, if nothing else to prove to the Debian folks yes, this thing should work under your distro, so why doesn't it?

I've already tried with F41 with no success. Someone in the FW community recommended preparing a USB stick with live Windows (yeah, that's actually a thing and wasn't discontinued with Win8) and trying that. Because if it works on Windows, Intel won't have any way of claiming it's not their fault that it's not working. Right now, I'm waiting for my USB stick to arrive. It's recommended to have one with at least 64 GB, and local electronics stores only have cheap garbage sticks that either are only USB 2 or might just break in a day or two. Sadly, this order takes an eternity to arrive.
