Wireless laptops not automatically finding DHCP

[bondbill2k2]

Having joined around 100 laptops to our domain about 10 are having problems finding the DHCP server. When assigned a static IP they work fine and wired in they also work great but soon as you attempt to auto assign on the wireless the laptop connects to the wireless then has the limited/no network connectivity warning. I have ran ipconfig /release wireless then renewed plus netsh winsock reset before leaving the laptop off for several minutes and rebooted but still no joy

 

I have set up most the laptops with reserved IPs for now so they can be used but ideally I would like to solve this issue, having read similar problems the above and reinstalling NIC drivers have worked but this also didn't help.

More information may be needed; wireless system, encryption, network structure (vlan'ed?), DHCP server config...

Wireless is Cisco Aironet 1142 APs managed by Cisco 5500 WM. SSID visible with WPA2-PSK.

Network is 2 vlans for admin and curric, DHCP server in curric vlan and clients set to obtain IP automatically.

try setting up the DHCP on the cisco controller , see if this works first .

 

Then disable and look for something on the controller thats blocking the port

Are all the make/model of the laptops the same. Could some have slightly different wireless chips.

Can't believe I didnt check it first, DHCP was moved over by LEA but wireless interface on manager hadn't been configured to the new server. Strange how some devices picked up the new IP tho! *facepalm*

kindly restart the service of DHCP by typing service.msc command
