At about 11:50 PM tonight, my AirPort Utility automatically opened and told me that I had "No DNS Servers." I don't know what that means and before I could figure out how to fix it, it fixed its self. Then it told me to preform "Double NAT" mode, in which I should use "Bridge Mode." I don't know what is happening here. I never have any problems with my AirPort like this. Should I be worried? Also at about 11:40 PM there was a bright flash outside. It wasn't lightning, although there is a chance for some later tonight. Just seemed weird at the time. Maybe some wire on the ground transformer blew up. Who knows? Either way, the internet is fine but the Airport behavior is bizarre. Also my stereo system turned on magically just now while writing this. It has been off for weeks!!! WTF! Maybe I lost power shortly?
