Hello Malik,
1 - Plug your laptop into the same switchport the AP was plugged into and configure it for the same vlan. Does it pull and IP address?
2 - Configure your laptop with a static IP address for said VLAN and connect to the wlan. Can you ping anything on said vlan, namely the DGW, DHCP server, other devices.
3 - Make sure that the switch the APs are connected to are also trunked allowing same vlans through
On the AP you can run the following command to see where DORA is failing:
#service pktcap on interface ge1 count 100 filter port 67
Try to connect your wireless device at this point and check the output.
I hope this helps
