Weridest thing happened yesterday.  COntroller OC200 just updated to newest firmware as well as the ER605 router.  Now one of my AP disocnnected and cant be seen. it only shows up now when it is powered with an injector.  I have 4 other APs in my system that are all hardwired back to the router via other switches and no problem.  I had 2 extra AP laying around from a previous job, so I tried to adopt them into the system.  they only show up in the deivce list if they are powered from an injector now.  Previoulsy they were all powered from POE switches.  THis is very weird and cant figure this one out.  Any help would be appreciated.
