I have noticed that my new Roku XD knocks out the Internet connection via my Linsys wireless-N router. Roku works fine for a while, but usually during the overnight hours, the wireless router looses its connection to the Internet. When this happens, no wireless devices in my house can access the Internet. If I power the router off and on, it is able to re-establish an Internet connection. I'm sure it is the Roku, because this does not happen when I unplug the Roku overnight. When I plug the Roku back in, it usually works fine long enough to watch a movie, but it always eventually knocks out the router. Before the Roku came to my house, I only needed to reset the router once or twice per year.
Has anyone had a similar experience? I think it may be a configuration setting on my router.
