Hi Kaygirl, I also am having issues with the internet and my receiver, but my issue is with my HR44-500. When I first got setup it worked fine for several days; long enough to get the On Demand and other features activated. Then I got a FW update to 0x0D80 and it has been garbage ever since. If I completely wipe and reset my internet settings, along with a reboot it will work again for a few hours at most, and then it will disconnect with the "Reconnect" error in the menu. A normal reconnect process does not work at all; I have to go into advanced IP settings and manually set my IP and then reload the box.
It's frustrating as hell; I just switched to DTV from Dish and it has been a lot of pain. I've tried talking to reps and they just have me go through the reset process every time; they have never mentioned any known issues with an update. Sorry you're suffering from it too, but OTOH I'm glad to hear that I'm maybe not alone.
