Compute Module • Question on built-in 802.11 + current Raspberry Pi OS driver

Hello forum,

I have a need to lower the MCS rate of the built in 802.11 radio of a CM4. With other wifi radios I've used, I've been able to use command like:

Code:

sudo iw wlan0 set bitrates ht-mcs-5 0 1 2 3 4 5
that will let me set the MCS indexes that will be used. With the driver that ships in the current version of Raspberry Pi OS (64 bit), when I execute this command I get an 'operation not supported.' I believe this is because the driver that is being used does not support setting the bitrate via the iw utility.

By question: Is someone doing this, and if so could you let me know your method? Thx!
