Making some progress. Still have the 10-20min outages where the TV channels(except for the WX Channel) stop working. In addition but not a fault of the service, I was also experiencing many drops per hour. That seems to have been caused by a non-compatible WI-FI adapter. The non-compatible WI-FI adapter was included in the box along with the Z7+. I ordered a replacement adapter recommended by the Formuler forum. Inamax USB WiFi Adapter 1200Mbps, USB 3.0 Wireless Network WiFi Dongle with 5dBi Antenna from Amazon
As I am typing this, 11:45 EST, the TV channels just died except for the WX channel.
