Yep. I actually have two linked wireless routers hooked up to my cable modem, but I do everything wired anyway. Since I work from home, my workstation has to be wired and takes up 2 jacks (internet & VOIP). And because of the way my IT has things rigged, I couldn't use the router that came with my upgraded broadband last Dec., and had to hook up my old router to the new router so that my IT people can still remote in to my workstation. And they lost the password to access the wireless so my own 2 laptops are wired to the router as well, plus my Wii when I'm using it.
