Thanks. I checked out what he had to say - s/b helpful when I get to the actual Roku set up (however, I think my player is much older than his).
But, the problem's not only with the Roku, but all wireless devices. It seems that the router is not broadcasting a signal that any wireless devices can pick up (I hope I said that properly). For example, my laptop had been connecting fine to the Internet, and now when I try to get it to connect through the router, it says that no devices are available (or something like that).
