I had the exact same problem this morning. It has worked fine for 6 weeks straight with no issues. As I was heading out to work, I only had time to do basic troubleshooting (restarted router, had item request IP address again, which it got a new one so I know that's working). I plan on digging into it more when I get home, but that really makes me wonder if Dish didn't do something last night that messed it up...?
