Hi,


I have a newly configured 5508 and a test 1252 ap. The ap connects to the controller and then drops off repeatedly. I have pasted the errors that I am seeing on the ap below.

Hello,


Based on your log, AP does not progress  after the Join request is sent to the WLC..


Can you get us a debug output from the controller if its not in production ?This will tell us whether the Join request was received or not and also what is happening at the path MTU discovery stage.Also what is the version of code on the WLC ? remember reading about a bug that prevents APs with  MACs starting with 00 from joining the controllers  but that was for 6.0.188.0.Last not least ensure that  NTP is working as well as that could be a culprit as well.


cheers,

Janesh

Thanks for the reply,


I have checked the time on the wlc and it is correct, it didnt have an ntp source but I have added one. The sw version is 6.0.199.0. I turned debugging on for the wlc and get the below output over and over again. There is no duplicate AP as this is the only one connected.


Many Thanks,

D

Have you found a solution to this problem? I am also experiencing a problem with an AP joining a controller. I have a wlc 2012 with 1131ag access points. Currently have 6 AP's on the controller and the 7th is throwing the following error and not fully joining the controller.
