Okay, I've read all the set-up guides etc... We just got new internet today. Our old internet was the built-in airport connecting to our stupid SLOWWWWWWWWW hughesnet internet. Now I have an AT&T aircard that's fast, but has a 5 GB per month bandwidth limit. I just plug that into my USB, open the "sierra wireless watcher" application, and click connect. quit, and i'm good. Since it's not an airport network, how can i set up time capsule to find the network? I tried plugging the aircard into the USB of the time capsule, but I'm not sure if that works, or where to go in the airport utility once i do that. Will backing up my computer use up the bandwidth?
