I went tonight and purchased the airport express, once I got home, I realized that it would not bridge my airport base station (b vs g), so I went back to compusa and bought an airport extreme base station. The extreme replaced my b station. What I was wondering is if I set up my old base station in another room as a bridge to help bring my internet to the front of my house, will having a b on my new g network effect the speed of the network or would I be better off trying to sell it. BTW I love airtunes, so awesome!
