Hi, I've just bought the Airport Extreme and will be using it to wirelessly connect an iMac to the Internet. I now have a left-over Airport Express. I'm thinking of putting it in the kitchen so that I can use AirTunes to stream music from the iMac... However, if I do this, will it slow my network from N speeds to G speeds? If so, will the slowdown occur all the time, or only when I'm actively using Airport Express to stream the music? This is all probably terribly basic, but I don't know a lot about networking... Cheers, Steve.
