The X2000 is a good gateway[modem+router]
After buying the Linksy X2000, I discovered it will work as a gateway (modem+router) only
if you have a DSL connection. I use Cable so I was never able to test or use the gateway (modem+router) feature of the Linksys X2000.
I also have a new, unused Linksys WET610N, "wireless gaming and video adapter" which I assume
does the same thing as a Roku player. I'm uncertain about the best use for the WET610N. My Roku player is working as advertised; but now, use of the WET610N is a Roku-related concern. Comments and suggestions are invited.
The WET610N is a wireless bridge, a device that will talk to your router wirelessly and provide a wired connection to network devices that aren't capable of wireless connections themselves, like older game systems and some blu-ray players and tvs. Not really anything to do with a Roku, since all Roku's have built-in wireless.
Although, one thing I've done in the past was to connect a wireless bridge to a 4-port switch, for a bedroom where I had a TiVo, Roku, and desktop pc. This was a Roku 1 and rather than fiddle with the wireless setup on it, I just connected it to the switch I was already using for the two other non-wireless devices. Everything worked very reliably, although I eventually replaced each of the components for other reasons and didn't need the setup anymore.
