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.

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

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

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

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

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).

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

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

i've attached the sh sysinfo

below are sh time

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?

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.
