Hello there , I'm thinking of buying an airport express as an extender for my home network (for the time being, later I will use it as my main router). My question is , if that is possible, I've heard that routers that do that , will cut the speed in half.Is that referring to the network speed ( as in 300/2 for wireless n ), or my actual speed , which should be about 12 mbps? Thanks so much!
