I'm not too sure which type of router I should buy. I'm clueless about routers, actually. I'm currently using a desktop that is directly wired to my modem. I'm looking for a router that I can attach to my modem(I think that's how it goes?) and in turn, the router will be wired to my desktop and be wireless to my laptop. (I plan to purchase a Macbook as my laptop, do I need a special router?) Also, I heard something about the Airport Extreme. Not sure if that's the only router I can use? Again, I'm clueless to routers.
