One company I like would be Netgear. In my opinion, all wireless routers serve one purpose: to distribute a way for devices to connect to the Internet wireless or wired; the router acting as the provider. I like Netgear due to its affordability and its simple interface. The basic model supports "G" range; which should be DSL speeds. The "N" range, as far as I know, supports up to 300Mbps, which is insanely fast. So if you have some fiercely fast internet connection with fast speeds, then the "N" range brand is the one for you; since HD media streaming and internet surfing would be a breeze.

What you choose is up to you, your preference; all the routers perform the same function.
