i am having issues joining new 1242LAP's to my controller. i am receiving the follwing error on my controller:
AAA Authentication Failure for UserName:5475d01144f0 User Type: WLAN USER
username is the MAC of my new 1242LAP. older 1242LAP's have no issue. i have 70 of the newer ones that i have just installed and fail to join the controller with the above error message. i'm not sure how to resolve. any help would be appreciated. thanks.
