Hi Peter,
I think that perhaps what Lancer meant by master mode is that at present ASIAIR can only set itself up as the Access Point of a network.
As such, ASIAIR will have an SSID, the familiar ASIAIR_xxxxxxxx string, unless you have changed it yourself. The hex digits following "ASIAIR" come from the ARM chip's Processor ID (which ZWO also use for licensing).
Somewhere in your mount, there should be a menu setting to set the mount up as WiFi station mode, and a place to enter the ASIAIR's SSID. Additionally, there should be a menu field to enter the WiFi password of the access point (12345678 in the case of the ASIAIR).
Since the connection between the mount and ASIAIR needs refer to the same IP at both ends, you cannot use DHCP. So, set your mount to ignore DHCP, and choose a fixed address of the form 10.0.0.n, where n can range from 2 to 254. (1 is the ASIAIR access point itself, and 255 is the broadcast address).
As long as no one else (WiFi extenders, desktop computers accessing the SD card, etc) is using the same IP address to connect to ASIAIR, you can pick your own fixed IP address. To avoid collision, it is probably safe to use some number in the middle, like 100.
I don't think ASIAIR cares what number you actually use, as long as no two WiFi devices are trying to connect to ASIAIR using the same IP address.
On the ASIAIR side, in Telescope Settings, you will want to select Ethernet, and use this exact same 10.0.0.n IP address. You will also need the Port number that your mount listens to, which you need to get from the mount's manual.
