[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

[schwidi]

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...

[schwidi]

I had a Comfast WiFi Stick with 7612u chip before. Worked perfectly as far as the blue operation LED does not light up.

@schwidi

Tim's suggestion is the right one.

Nevertheless, I'm curious. You haven't yet told us actionable details like

- what release of moOde?
- what model Pi?
- what physical USB port is your external adapter plugged into? (note the comments about this in the USB-WIFI reference you provided)
- if this model Pi has an integrated WiFi adapter, then how do you know which adapter is being used in the connection to your Access Point---integrated or external?

What is the output from executing the following command in a terminal window

Code:

iw list | grep Cap

Note the output from 'iw list' is quite voluminous which is why I suggested grep'ing on just the Cap(abilities). You could instead post the entire output.


Regards,
Kent
