I have the same issue with radio1 as can be seen below

I have tried wifi up and wifi up radio1 commands but it dosent work.

The device under use is RPi4

What radio hw ?

This is same for 3 different radio HW
Tplink MT7600 LAN adapter
RT8812 wifi adapter
TPlink AC600 wifi adapter

4

They all RTL based, by any chance ?

5

Two are RTL based one is MT76xxu driver

6

The RTLs are probably dead ends, the MT, is it wired or wireless?

7

MT is wired USB to LAN adapter, AND is there any specific reason for RTL's failure

8

Then post the VID and PID for the MT.
The RTLs seldom support AP mode, due to mediocre (at best) support from RTL.
