I'm interested in maybe getting a Time Capsule and updating my router at the same time but in doing a search of these forums, it seems that many people are having problems with their Time Capsules. I can't seem to find anything on somebody hard wiring their Time Capsule to their iMac and letting it back up through Time Machine via a hard connection instead of over wi-fi. It seems that when TC backs up via wi-fi, it slows the network down. I'd like to ask some questions and if you know the answer, please respond to which ever question to can. 1. Can you connect the TC via an ethernet cable and have the TC back up that way or does it only back up via wi-fi? 2. Can you set a time when the data is backed up or does the system somehow select a time? 3. Does the TC back up when the computer falls asleep or must the cimputer be awake? 4. If I just buy an extenral hard drive and connect it via thunderbolt, is there anything different in the process that I need to be aware of? 5. If I use an external hard drive, I won't be connecting it via an ethernet cable so is there anything to keep in mind with this set up?
