If the controller is a 3650/3850, post the complete output to the command "sh ntp a". 

[ljustl]

all the times are set as current. that is from couple days back. i did set WLC current time on GUI.

controller = 2504

core = 3650

access = 3560

[Leo Laohoo]

On the controller, post the output to the command "sh time".

[ljustl]

its current. i modified on GUI. Do you still want to see it?

[Leo Laohoo]

take a look at from_ap txt, it's from today

AP_message is from July 8.

That's why I'm suspecting the time-and-date settings for the controller is off.  Today's date is NOT 08 July.  Today is 15 July 2017 (unless you're in a time warp).

[ljustl]

right, but as i mentioned, that debug details are from july 8 and there were no changes made. I'm stuck since then.

[Leo Laohoo]

Post the complete output to the WLC command of "sh sysinfo".

[ljustl]

i've attached the sh sysinfo

below are sh time

Maximum number of APs supported.................. 5

How many APs have already joined the controller?

[ljustl]

i have two connected, but not associated with the controller. 0 found.

Product Version.................................. 7.6.120.0

I must be getting old.  

Ok, so the controller is running a very, very old 7.6.120.0

And the AP is a 3702I ... but a -UX.  

Now, -UX APs were first supported with 8.0 controller firmware. 

So, upgrade the controller to 8.0.X and see if it improve things.

[ljustl]

okay, i will try to upgrade to 8.0.140.0 on controller and let you know.

Does it mean that -UX APs are not suppported on 7.6.120.0?

[ljustl]

after upgrading to 8.0.140.0 AP joined WLC. So -UX APs are not compatible with 7.6.120 ios????

1 of AP is still blinking green and red. but i guess i can manage that.

I have another AP that is not joining WLC. i reset the AP and it's keep rebooting.... error message below..

So -UX APs are not compatible with 7.6.120 ios????

2700/3700 -UX APs are supported from 8.0.X (and later).  

1 of AP is still blinking green and red. but i guess i can manage that.

After the AP has joined the controller, the "-UX" domain needs to be provisioned and this can only be done using Android/Apple app.
