Question

I just bought a Linksys router WRT150N this evening. I have a Dell router that is problematic. My modem and existing router are on one side of the house , my Dell desktop on the other with "no" hard wire connection. Is it possible to use this Linksys router without a hardwire connection between my modem and desktop.
