My wife and I are in the process of expanding our home office to take advantage of our son's recently vacated room (he's gone to college for the next 3 1/2 years out of state.) We had a wireless "B" network for a few months so my son could use his laptop downstairs. Our two desktops have been always been wired. When my son left, I let him take the wireless router. Now, I am moving my station/A/V desktop into his room, and we've decided to go completely wireless, with plans to put a third computer downstairs. We see that Linksys has a wireless "G" system with Speedbooster. Can someone tell me what the advantage of Speedbooster is? or is it something that I really don't need?
