I am sure others are having the same problem
Received my Time Capsule this week and installation went very smoothly and worked just as advertised. Set up Time Capsule as my base station and as prior extended my network using 2 Airport Express. My old network consisted of an Airport Express (802.11g) the older model, and extended by 2 Airport Express which are also (802.11g) Since the Time Capsule is the newer (802.11n) faster thought it would be nice to upgrade the Airport Express but they are only (802.11g) so I bought a new Airport Extreme to use to extend my network. I have to get full coverage to my whole house. YOU CAN NOT USE THE AIRPORT EXTREME to do this and the Airport Express are all (802.11g). So now I have the new MacBook Pro 2.6Ghz with 4 GB ram and a base station with the faster network speed and I am stuck with the old outdated speed of (802.11g) because of the Airport Express. APPLE NEEDS TO UPDATE THE AIRPORT EXPRESS!!!!!!!!!
