Need more info than this.

When the WAP disconnects, does it loose power or just disconnects from the vWLC?

Looks like your AP is on dynamic vlan interface of wlc.

soln: on WLC, remove that dyn int where AP is on or move the AP to vlan that is not part of dyn vlan int of wlc.

no the AP is on a POE switch and is always powered on .

there is only one WLAN called DATA , mapped to dynamic interface DATA which is in vlan 2.

how AP is connecting/reaching WLC's management interface?

AP trying to reach the management int of wlc through port-1 that is mapped to vlan 2.

what's the AP vlan?

it seem AP vlan is vlan 2, which is also an dynamic interface of wlc. either move the AP to L3 vlan that is not vlan 2 or put the ap on management vlan of wlc to fix this issue. (Note: AP can't be on dyn interface of wlc per cisco. you can still have this option that is not supported by tac just by enabling mgmt via dyn interface, and also it is not guranteed that it works stable)

no the AP is on a POE switch and is always powered on .

If you look at the WAP details after it disconnects, what does the UP time and WLC Association time like? Please provide screenshot.
