so, i'm thinking about getting a time capsule as a backup hard drive for college, but before then i want to use it as a wifi router in my house. is it possible to hook up a dell running xp via lan cable to the time capsule and still use the time capsule as a wifi source for a macbook so that both have internet? i'm assuming it is, but i just wanted to check to make sure that a macbook wouldn't have any problems with the wifi or time machine if a dell was using it too.
