How are ExtAP settings configured?

Hi!

I’m wondering how Windows configures ExtAP settings, such as channel and PHY
type. I assume that if the ExtSTA (port 0) is associated, ExtAP would
inherit the current settings for channel and PHY type.

However, I’m working on a project in which the objective is to support
Wireless Hosted Networking in a configuration where the ExtSTA is not
associated. In this case, how are the settings for channel, PHY type, and
other options set by the OS?

More to the point, is there a way for a user-mode app to control these
settings? I don’t see anything documented in the Wireless Hosted Network
documentation, so I assume this can only be done through a proprietary
interface to my WLAN driver. Is that correct?

Thanks!
