Channels losing connection with HDHR Prime

Recently, Channels has been stalling (frozen picture) and the losing connection with my HDHR Prime (shows yellow triangle with ! and “Connection Lost”). The ATV still has a WiFi connection since I can use other apps. Sleeping/waking the ATV sometimes works for reconnecting, but it usually needs a restart from settings>system. The SO got fed up with it so I downloaded InstaTV tonight and it has been playing without issue. Anyone else seeing this issue?
