MT7922/RZ616 Windows Hotspot Channel Settings

Windows Hotspot allows you to easily create an AP (Access Point) from your existing Wifi card. Many computers such as the ROG Ally have a variant of the MT7922 chipset which supports Wifi 6E and it can be used to create a high bandwidth P2P connection for game and VR streaming. Unfortunately, Windows does not provide much support for configuration of the AP channel and bandwidth. Fortunately, it is possible to change these from some registry entries. Note that you must reboot for the changes to take place.

The location of the registry key is inside HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class{4d36e972-e325-11ce-bfc1-08002be10318} and depends on the order the network devices are installed on your computer. For example, it is HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class{4d36e972-e325-11ce-bfc1-08002be10318}\0001 on the ROG Ally. Look at the data for value DriverDesc to confirm that you are in the right key.
