Our 722k with software L6.88 loses it's connection with our broadband WiFi every couple of days. We can try all the on menu/onscreen procedures and the only thing that will restore the connection is pulling the receiver's AC plug out for ten seconds. We are using the Dish/Netgear BB WiFi Connector with a Netgear WN3000RP Wireless Range Extender which gets a very good signal, when it's connected it's in the 90's. When everything is working, the streaming pictures look great. Anyone else run into this problem?
