I have had a a number of airport expresses since they came out. They all seem to need to be reset fairly frequently... every 1-2 days. By reset, I mean unplugging it and plugging it back in. What could be causing this? Would we encounter the same issues with an Extreme? Also, what is the difference btwn an Airport Express and Airport Extreme. I use my Express at home btwn my iPad, MacBook, iPhone, (new iPad when it arrives), and my husband's PC. Would we be better off with an Extreme? My husband wants something more reliable and faster. Our Express is at least a year old. We don't need to plug our computers directly into the Extreme. Also, is the Time Capsule just and Extreme with a hard drive? I do like the idea of constant back up. Thanks!!
