Mel, Thanks, for all the detail. Everything is in doors and directly connected by new 3 to 6 foot manufactured cables on a cisco switches. All cables have been changed - even tired crossover cables - same results.
I'm thinking it has something to do with the controller communications...All these APs shouldn't need a controller after configuration and boot up. But we leave it up.
