Only reason I could think of is extended range (1 at each side of the house). I'm not 100% positive how well they would cooperate, but it should be theoretically possible (as long as they operate on separate channels and your devices know which one they should use).

...Ok, now I'm confused.

You want a wireless router to share your internet connection - good, that's common.

You want a wireless router for your wireless connection... now I'm confused. oO If you're not dealing with range issues, couldn't you just use your wireless router on the internet connection and not buy another?

Ah, then you just want to use it as a hub, not a router. I do the same, though my server acts as the router. Yeah, make sure you disable DHCP, all routing services, and give it a static IP somewhere on your network (I made mine 10.4.12.254... I have a rather full class A myself).
