J_Edit61 I was not able to make a connection within ASIAIR.
Be sure to give the ASIAIR app "Local Network" permission (check Google if you don't know what that is).
Connect all cables, and boot up the ASIAIR device, and only launch the ASIAIR app after you hear the beep from the device.
If you still cannot see the ASIAIR, try tapping the Scan button (each time waiting until it finishes scanning) repeatedly until the app finds the ASIAIR device. It could take more than a dozen tries. The ASIAIR network code must have been copied and pasted from somewhere else since it is highly unreliable. But you should eventually see the ASIAIR device. (Be sure to wait for the beep from the ASIAIR device first.)
It even happens on a iPad Pro using a USB-C gigabit Ethernet dongle.
Now, once you get in, go immediately to the ASIAIR Settings window (where the ASIAIR app shows networking info) and there is an item called "Wired Internet." Write down the IP address (for example, for one of of my dongles, it is 169.254.186.44). If the Scan fails in the future, use "Connect using IP" to connect to this IP address.
Remember that you should wait for the beep from the ASIAIR device before you launch the ASIAIR app.
