Actually, I had some problems:

# iw wlan0 set bitrates legacy-2.4 1 6 12 ht-mcs-2.4 1 2 3
command failed: Invalid argument (-22)
# iw wlan0 set bitrates legacy-5 1 6 12 ht-mcs-5 1 2 3
command failed: Invalid argument (-22)
# iw wlan0 set bitrates legacy-5 vht-mcs-5 7 8 9
command failed: Invalid argument (-22)
# iw wlan0 set bitrates legacy-5 24 ht-mcs-5 vht-mcs-5 1:0-9
# 

The first one I understand as this CUS223 board only supports 5G. But
why did the second and third command fail?
