[PROBLEM] No WiFi 6 with MT7921 USB Wifi stick

[TheOldPresbyope]

Try the command below. Its used in Network Config

Code:

nmcli -f CHAN,RATE,SECURITY,SSID -t dev wifi

I suppose one could try to infer the protocol in play based on the reported rate but that's problematic because the supplicant and the access point negotiate the modulation and coding scheme (MCS) they'll use, which affects the rate.

I can't find any option in the commands available in Raspberry Pi OS Bookworm which will report the protocol directly. Interestingly, there's info on the InterWeb™ which suggests

Code:

iw dev wlan0 link

should report HE, VHT, etc., and the MCS index as part of its output but the version we have (5.19) doesn't appear to do that. The current source-code version in debian testing is much newer but I don't know if building binary from it would help.

Sigh.
