modem heats uo how do you stop?
say u have a wireless modem/router and you want to increase network conection in an area of you building with out buying another wireless modem/router wat do you get? an adapter a router a HUB anything at all?

first of all, modems heat up, thats what they do to operate at optimal efficiency, secondly 2 of your questions can be answered with one product, a wireless N+ Modem Router from belkin. Shop around and see which one you prefer.

have a look here, may be a bit expensive though
