Hello! We just got our first Roku Netflix player last week. So far, every time we have tried to use it, we've had the identical problem -- we'll get about ten minutes into a movie and it will interrupt to load more of it, and then just freeze there. We'll go to one of the computers in the house (desktop is wired, laptop is wireless, Roku is wireless), and the internet connection will be dead, even though our cable modem still has the flashing "Activity" light that is supposed to mean the connection is active.
While the Roku is in the frozen screen trying to load more of the movie, nothing can be done about the disconnected internet connection. If we try unplugging the cable modem and wireless router and plugging them back in, we still can't connect to the web from any computer and nothing changes on the Roku. If we exit the movie and return to the Home screen on Roku, however, and THEN unplug and replug the cable modem, poof, suddenly the internet connection returns.
This happens even if we are ONLY using the Roku and not doing anything else on our network, so it doesn't seem like it could be a bandwidth problem, unless the Roku uses a TON more bandwidth than streaming Netflix movies on a computer does (we'd been watching movies on our computer for months prior to this and have only experienced this problem since connecting the Roku).
Typically, this happens ten or so minutes into a movie, and then we restart everything and it'll be fine for the rest of the evening. Does anyone have any ideas about what might be causing this problem? Or things I should try in order to further diagnose or fix it?
