Thank you for your reply!
I like to use the 5GHz network from the Asiair mini, so I cannot use the ASIAIR in station mode (AFAIK).
If I connect the mount (in station mode) to the ASIAIR access point, then I have no way to connect to the wifi of the mount anymore, because I do not know its IP address.
It would be good to know, what IP addresses the Asiair asigns to connected devices.
