What wireless router has the best range and strength of signal?

I'm considering buying a new router for my XBOX 360 because the one provided by the cable company for our wireless internet is not very good. I was wondering what you thought has the best range but still keeps a pretty good signal?|||Try Linksys! But put it in the center of your house and make a password for it.|||Netgear 802.11B/G/N. That's the way to go...
