question for Intel MU-MIMO setting for AC-8265

Hello all,

it seems my laptop with Intel AC-8265 doesn't support MU-MIMO.

I'm using ASUS-RT88U as gateway, and it proves it works with Samsung S7 for MU-MIMO. but when connecting AC-8265 ( install on my DELL laptop) with Intel PROSet/Wireless WiFi Software version = 20.10.2

• Driver version = 19.10.10.2 for Windows 7 for 18265, 8265, 3168, 18260, 8260, 17265 and 3165.

During the capture packets, it shows Sounding and MU request send to AC-8265, but still get SU feedback.

please help to check how to enable the MU-MIMO for AC-8265

Thanks
