I have an Airport Extreme that bombed out. I was going through a routine power cycle after recycling my modem and I noticed it did not come back online. I got into the Airport Utility and although I could see the Airport Extreme and could read its data, the Airport Utility would error out each time I tried to hit Configure. I disabled all my firewall settings on two different PCs and still no dice. Tried the Airport Utility on a Mac Mini and still no dice on configuration. I reset it back to the factory settings thinking if I rebuild it, it would work. Still no dice. I get various error codes like -6722, -1022 and -4 but it will never configure. I then got a new Airport Extreme thinking the old one had some kind of mechanical failure. I opened the airport utility on the same mac mini and tried to configure. It could again see new Airport Extreme but when I hit the configure button it said "error in communicating with Airport Express" with no error code and would not configure the Extreme. WHAT AM I DOING WRONG?
