I just moved my TC from my parents house to my apartment and I tried setting it up and adjusted some of the old settings in airport utility and it told me the TC had to restart but now it's flashing amber and nothing is showing up in airport utility. I set it up to connect to my existing network and extend it. The same thing happened to me at my parents house and I don't remember what I did. I have backups and files on it so I really don't want to lose any of those. What should I do?
