Although I setup the T2x with the WiFi network ID and password, the unit is not connected to the network. I looked for its Mac address on the router and a 3rd-party utility.

I also did click on "USB" as you suggest, but there are no units listed as connected to the network.

I just noticed the following on the RTI site: "Can be remotely updated wirelessly from offsite (future support)." Not sure if "future support" is still correct.
