Need a fast wireless router?

First of all, your ISP determines the speed of your internet. If you have DSL I doubt you will ever get 200 mbps. If you go with fiber optic maybe. And about the router, you will need something that is IEEE802.11n, and note the 'n'. With 'g' you will get a max of 54 mbps, with 'n' you might get 100 something. You might want to do some research as you don't really sound like you know what you're talking about. Try someplace like Staples. I know for a fact that they sell 'n' routers and I think they are about $100.
