Hi, my name is Kelly, and I'm an independent consultant and I'm here to help.
Yes, it is possible to configure QoS WiFi features such as WMM (Wi-Fi Multimedia) or SCS (Spatial Streams) with Windows 11. Windows 11 includes built-in support for these features, and you can configure them in the advanced settings of your wireless adapter.
To access the advanced settings of your wireless adapter:
Open the Settings app by pressing Windows key + I
Click on "Network & internet"
Click on "Wi-Fi" on the left-hand side
Click on the name of the Wi-Fi network you're connected to
Click on "Properties"
Scroll down to the "Advanced options" section
In the advanced options section, you should see settings for WMM and other QoS features. Note that the specific settings available may depend on your wireless adapter and the capabilities of the Wi-Fi network you're connected to.
