AEBS as WDS to extend network

I have a Linksys WRT610n dual-band router connected to Cable modem. I have a desktop connected through ethernet and some wireless clients. This main router is setup in office room upstairs. Everything works fine here.

In my family room downstairs, I have the entertainment center which includes PS3, HTPC, Bluray player. I would like to connect all these devices via ethernet to a WDS-enabled router, in turn to main router. I know, some of these devices have built-in wireless client, but I want to use the ethernet port.

My question is, can I purchase a Airport Extreme Base station for this purpose? I want the AEBS to connect to my existing router over wireless and provide internet connection to these devices through ethernet. I believe it is called WDS. Can AEBS be configured in WDS mode to connect to non-Apple branded router?

Anyone??

I do basically what you're wanting to do currently except mine is connected via ethernet. I connect my Time Capsule (would be equivalent to the AEBS) to a D-Link router.

I did a test for someone else about a year ago and was able to set it up connecting wirelessly to the D-Link and then used the ethernet ports from it to connect everything in the entertainment center including my HTPC.

About the only thing I remember now is setting it up to extend the existing wireless network and don't remember it being that hard to do. I'd make sure you have a good signal in the location you want to put it, before putting your cash out for one. And I don't mean your computer sitting close to where it would be, but with it sitting buried in your entertainment center with all the other stuff.
