Hi,
I know that this topic is repeated so many times but still i did not get any help out of them. I am really greatfull to all of you guys who are making efforts here to help out others.
My Scanerio is that i have connected vWLC (On Vmware WS) with Cisco 3750L3 switch and my GW is FW. I have created 2 VLANs (VLAN10 and VLAN20) respectivly. I have a DHCP and DNS server, installed on Windows Server 2012 (VMwere) with scopes of DHCP, one for VLAN10 and one for VLAN20. all my devices are connected with VLAN10 (10.1.1.0/24) and only AP is connected with VLAN20 (10.1.2.0/24). Configured IP Helper command under VLAN 20 so it is communication with VLAN 10 and all network.
AP is getting DHCP IP from windows DHCP server and can ping to vWLC but its not pinging to DNS server and DHCP server which is on VLAN 10.
and when im trying to get registered AP with vWLC ( 7-3-101-0), it does not get registered and showing below logs.

Can you post the complete output to the vWLC command of "sh time"?
Console into the AP and reboot the AP. Post the entire boot-up process. We want to see what the AP is doing.
