MediaTek MT7925 6GHz not working

[ijack]

My saga to get MT7925 working continues I got a new Mini PC, and now I was able to successfully create networks in AX, BE modes; 2.5 Ghz and 5 GHz bands, and connect to them.

However, I can't get 6 Ghz band working at all in both AX and BE.

I am running Generic x86/64 combined-efi (ext4) built online with kmod-mt7925u kmod-mt7925-firmware wpad pciutils usbutils packages included.

Please advice!

6GHz is permitted in US only in client mode, as per upstream kernel wifi regulatory database.
You can check with iw phy that it is still true.

[ijack]

Hmm, I just tried US, JP, and DE. Still the same error. I've set it back to US...
iw phy is too long to paste here. https://pastebin.com/8ZwrPpg3

Any specific country + channel combo I can try so I can at least confirm it works?

[frollic]

you need a patched regdb for BE to work in US (perhaps other countries too ?) - Quantum Fiber W1700k support - #750 by stangri.

that thread is for the w1700k, don't post your questions there.

you could however try updating it using the apk posted at https://github.com/stangri/w1700k-wireless-regdb/releases.
apk implies snapshot, unpack it, and replace the file by hand, if you're on stable.

Got it working. It only works with WPA3. The packages required are kmod-mt7925u kmod-mt7925-firmware wpad-openssl The wpad does not work as it doesn't have WPA3. As long as I use WPA3-SAE and have 802.11w Management Frame Protection set to "Required", it seems to be happy transmitting with countries set to US, CA, DE, JP. I only see the AX mode now for some reason. And I was able to connect to the network from my other device.

The whole setup is a bit fragile, though... the network randomly does not appear on the other device while I change the channel, width, and country. But at the very least, 6 GHz is working.

No 6ghz, go protest your fcc.

There are bugs in the current Wifi 7 implementation. You'll have to navigate it with workarounds.

Quantum Fiber W1700k support

The community is hard at work getting the last major issue resolved and I am confident we will have this device completely functional in short order. Yay! It is still early days for WiFi 7 support in Openwrt, but having said that, this device is super cheap and works incredibly well. If you want the best Openwrt AP, this is it. If you want the best Openwrt router, this is highly competitive. If the limited ports are a problem, add a switch. Nonetheless, there are some minor issues (most…

I had similar issues with the 6 GHz band on MT7921u on MT7922. On 24.10, my laptop sometimes seen the AP, but it was impossible to connect to it. It didn't even work on the snapshot.
