Listen to the sounds if video is unclear.
Sorry, was watching it on mute.
If that config utility screenshot is current, then A) nice serial number!
and B) that is some extremely old software on that unit, with all manner of issues. I can't quite make out your Desktop version in that video but it may not care for talking to a interface down that far in revision. You should try to get it up-and-running in Infrastructure mode, connected to the Internet, and upgraded to current.
Edit: Screenshot in your shows Beta 14.8.1, which is latest. Wouldn't be surprised at all if it has heartburn talking to that as-is.
