I did some testing and searching, and it seems the ASIair can't connect in WiFi mode. I tried it for quite a while only in station/AP mode. I also scanned the Celestron while on the network and it's only listening on TCP ports 2000 and 3000; the latter of which is meant for maintenance. So port 2000 still doesn't work in the ASIair settings. The default of 4030 won't work at all because the mount doesn't use it.
However, it works great with a mini-USB cable plugged into the Eveolution hand controller. Note that it's mini-USB, not micro or USB-C.
