About 2-3 months ago, my 722 developed a new problem... When I attempt to access any of the DoD menus, I get the message "You must have a broadband connection...". So, I go into "Network Setup" (Menu-6-1-9-2) and "Connection Status" briefly displays "Testing...", then "Connected Online". (I don't recall this happening before; the status was always "Offline" - as when my router was powered off - or "Online" - it had never before displayed "Testing".) Once the connection is "awake", I can then browse DoD movie offerings and queue several for download. But, after about 20-30 minutes, my DSL modem shows no activity, and the "My Rentals" download status reports "This download could not be completed...". Accessing DoD menus again prompts the message "You must have a broadband connection...". Here's the weird part: after re-waking the broadband connection and queuing more movie downloads, any action requiring a network connection (browsing DoD movies, accessing the Network Setup menu, etc) seemingly resets this 30-minute window, allowing downloads to finish. (I successfully downloaded four movies yesterday.) Any idea as to what could be the problem? Specs: 722 (L721), connected to a 3 Mbps DSL modem via a Dish Powerline BB unit. And, yes, my 722 has been power-cycled several times since this problem started.
