You can try to reboot or use MP4.0 image to test whether there is a hardware issue

ok，update the firmware .It worked.

I have another question, how to display the MLO sta. What the command？

4

Imho you can use 6ghz only as extension to 5ghz not as dedicated ap. But habe not configured it yet maybe you have to bridge ap1&2 with hostapd and configure channels over 5+6ghz

@frank-w is this a specific recomendation for this module or something more general?

My experiences with a RF devices 2,4 / 5 / 6 Ghz module (MT7916) are that you have to decide what band you like to use actively 5 or 6 Ghz in parallel to 2,4 but in that setup 6 Ghz is working in general.

I got this info that 6ghz has to be bundled with 5ghz in general,not only this module…it is more specification of wifi7
