Ok, this is the setup: got an external hard drive hooked up to an airport extreme via USB. I have a macbook that's a few years old with the intel core duo processor and running OS 10.4.11. I want to be able to see/backup to this hard drive wirelessly from my macbook while on my home network. Basically, everything I've found online makes it look like I have to have my extreme on an 802.11n connection or whatever, which my macbook isn't capable of (intel core duo processor), right? The reason I say this is that all the instructions on how to turn this on circle around options that I don't see in my airport admin utility program. So is this possible, or am I gonna have to get a new macbook before I can do this. If I get leopard or snow leopard would I be able to do this with time machine, or do I need to be able to do 802.11n for that, too? Thanks in advance.
