im gonna buy a MBP...and my bro already has a windows pc...and i am looking for a good wireless router...for the past week i've planning to buy the new mimo netgear rangemax 240 wireless router for 150...because it can reach 240mps...but mine and my bro's computers both have built in wifi...and in order for the router to reach its full 240mps...we have to be using the wireless network notebook cards with it...so since we are not...is there a point in buying a router that expensive??...will i still get faster wifi if i buy it...or will i just be able to reach the 54mps limit that is in our laptops??....thanks for any help
