Thanks for your response. I probably should have given you more information, though. It isn't just a single roku that is acting up.
I have two rokus, one of which is only about 8 feet from the Belkin wireless router. That receives excellent signal strength, according to the roku. The other roku is upstairs and receives good signal strength.
I also stream Netflix througha Wii console in the basement. I'm unclear what that signal strength is, though. All of these are connected wirelessly to the Belkin router, which is a G-router.
At first the Wii streamed very nicely, which is why I elected to get the roku devices. Initally all of the streaming devices worked very well, but over the last week or so I have been having the problem I asked about.
It seems unlikely to me that a factory reset of a single roku would solve the issue, as all of the devices are acting up. I even tried streaming on the upstairs roku this morning, and the same problem occurred. I certainly could factory reset the two rokus, but I would rather not reset the Wii (my daughters have created a lot of Mii characters).
Would you recommend just replacing my Belkin G-router with an N-router? Would that do the trick? Or do I need to use hard ethernet cable connections to all the devices? The Wii consiole does not even have an ethernet port, so I would need an adaptor. I would also need a switch or hub (or upgrade to an 8-port router) to accommodate the additonal ethernet cables, so I would obviously prefer to keep things wireless... if possible.
Thank you in advance for your response.
