Tim I do agree that may be the obvious solution and possibly the one I finally zero in on. However, I still would like to determine if the reset/ reconnect feature in my 720 has some issues or maybe its purpose is just not what I think it was designed to do. Haven't really heard anyone that said "Yes my reset / reconnect button for WiFi works great". I do agree the hard wire switch would resolve the apparent issue but not ready to go there yet in this digital world.
Anyone out there wanting to give it a try, I would be interested in hearing from you . ie can you disconnect from wifi and reconnect while remaining in the NAv app. ?
