blin182, Firstly, 75 - only a theoretical limit, the actual maximum speed just needs to be around 50, all the losses count relative to it. Secondly, what rate does not drop much you does not mean that it also falls in others. I for example, two buildings stand around the corner, because of what I catch in 2 times more networks. Needless to say, that in 2.4 little space even for a house? Thirdly, there is such a thing as a public space in which, apart from you, to the router can be connected to a couple of dozen people.
