I am trying to get a wireless setup in my home that has a large range. My speed from comcast will be 20 mbps. I plan on getting a docsys 2 router as I will not need a docsys 3. As for the wireless part I am split between an apple airport or one of those rangemax routers. I see the rangemax routers come in different strengths up to 600mbps or something crazy like that. I hear that the higher the bandwidth on these rangemax routers, the greater the range. My question is, if my internet speed is only 20mbps, do I get any additional range by having a rangemax router with 600 mbps over say a lower 100 mbps?
