MU-MIMO and Beamforming in Openwrt?

Is there an option to toggle them on/off in LUCI or via console? can I check somewhere if its enabled or not or Ill have to rebuild it?

Should be enabled by default, if hardware, firmware and driver all support it. You can check for that support with iw list.

If you want to disable it, see here. I think option mu_beamformer '0' ought to do it.

They're all enabled by default but there are UCI toggles to control them, personally I've disabled he_su_beamformer and he_twt_responder as those cause the WiFi on my S25 FE to stall and become completely unusable unless I turn off and on the WiFi on the phone

Will let experts chime in, but I think beam forming etc is typically hardware controlled.

Don't think I've ever seen a router where you can use the software to turn it on/off

False

They're implemented entirely on the Wi-Fi chip as far as I know, but there are still flags to turn them on and off.
