Hi, I'm not sure if this is true or not, but I've seen it often repeated on the internet that as soon as a g device connects to an n router, every device on the network is only getting a g speed connection. Firstly, is that true? Secondly, will it be true with the new ac base stations Apple have brought out? Should I keep everything but my new MacBook Air off my ac network and on my n one? Apologies if this is obvious or is just idiocy.
