Hello. I currently have an Airport extreme running 5ghz N network. I send media to a few devices and need the extra speed. However, my xbox, printers, and iPhones do not run at the frequency. Now I have an airport express laying around. I was wondering if I could extend my current N 5ghz to the Express running 2.4 b/g. Can this work? If anyone has a better solution that doesn't involve buying a new Airport with the Dual band it would be much appreciated.
