ALL the speed boosters rely on same maker devices with same type capability (ie. speedbooster.) It's a safe bet your laptop has it's own wifi hardware and as such will not get a boost.
It seems after reading in between the lines that Speedbooster is really for networks that have several devices communicating with the router.
Currently I am connecting just one device (my laptop) to a router at speeds of anywhere between 11 and 54Mbps. My Comcast connection is at 10Mbps.
Will Speedbooster make a difference here?
