[PROBLEM] No WiFi 6 with MT7921 USB Wifi stick

[schwidi]

I bought a new WiFi USB stick with WiFi 6. Unfortunately, WiFi 4 only works although I am only 2 meters from the Xiaomi 6500 BE router.

It is a MediaTek MT7921 USB WIFI stick that should be compatible with bookworm.

Maybe someone can help me, or there is a driver that I can install with SSH.

Not that this will solve your issue, but being too close to the router does not always mean "better signal"; sometimes has the opposite result...

Where does it state that its compatible with PiOS Bookworm?

This link that you provided https://github.com/morrownr/USB-WiFi/issues/455 talks about wifi 6 support so I think your best bet would be to post to that issue. Mention that the Linux kernel version is 6.12.20

OK, thank you.

I actually also bought a usb WiFi dongle based on this chipset as well (yet to receive). Apparently it's supported since a way earlier Linux kernel. I'll report back when I have received and tested it.

Edit: not exactly the same dongle i now see. The one I purchased does not do WiFi 6....

7612U vs 7621...
