Having trouble connecting to 6 GHz band with mt7921au based adapter on Kali... #207

Help appreciated.

I am posting this for a friend and I don't have direct access to the computer. So, this is telephone tech support.

Kali is current and up to date.

He bought a new 6e (6 GHz) capable router. Can't seem to connect. Here is what he is seeing in dmesg:

[   33.796420] wlan1: authenticate with bc:0f:9a:49:05:fb
[   33.830284] wlan1: bad VHT capabilities, disabling VHT
[   33.830297] wlan1: Invalid HE elem, Disable HE
[   34.003014] wlan1: send auth to bc:0f:9a:49:05:fb (try 1/3)
[   34.017494] wlan1: authenticated

What the heck is that Invalid HE elem, Disable HE ?

It really does not look like an authentication problem. This is a new one one me so if anyone has any hints about how to connect a client to a new 6 GHz router on a 6 GHz channel, please speak up.

Thanks.

What country is the router set to?

What channel is the wifi?

Disable any mesh.

Set the channel width to 20MHz wide on the router.

What is the result of $ sudo iw list ?

What is the result of $ uname -a ?

What channel is the wifi?

Woring on getting these questions answered. I have already told him to run the router down to channel 37 to see if that helps.

Packet capture of the process would be nice, too.

Follow up: User switched to Ubuntu 22.10 as it works there.

Long distance tech support is a challenge. We were not able to determine what was up with his Kali installation but it looked to me like a wpa_supplicant issue. Ubuntu uses IWD these days instead of wpa_supplicant so that could be the difference.
