I'm currently using a Netgear router that transfers speeds up to 54mbps I believe, but recently I found out that when there is two computers using the wireless connection, the speed gets really sluggish. Now I'm seeing ads of these new "N" routers in electronic stores claiming to have speeds of 150mbps. First of all what is a "N" router? Would it help boost my connection speed if I were to buy a new router? Help!
