I currently have the first generation 1TB Time Capsule which only supports compatibility mode for 802.11n. Using a slingcatcher, I get better speeds (way less video stuttering) running 5GHZ only mode vs compatibility mode. However, running 5ghz mode is annoying because my Eye-Fi card and iPhone aren't compatible with 802.11n. So I have two options. 1) Keep current Time Capsule. Buy a used Airport Extreme for $100 or UFO one for $30-$50. Connect AirPort Extreme to Time Capsule. 2) Selling my old Time Capsule. Buy new Time Capsule 1TB. Price for the older Time Capsule 1TB is only $20-$30 less than the new Time Capsule.
