I bought an Airport Express yesterday since my LinkSys router crapped out on me. I got it hooked up and everything last night, it is hooked directly to my cable modem with WPA security on it. My MacBook does not connect to my system automatically even though I have it set to, my thought is because it takes a while to locate it for some reason when I come out of sleep or startup. Also my internet in ridiculously slow compared to my LinkSys with the same security and it was a g not n. Finally I was wondering if I connected an external hard drive into the usb plug if I could access that hard drive from a different network, or do I need to get a time capsule for something like that? If anyone has any help it would be much appreciated. Thanks.
