I was having this trouble with a new Dell laptop running Windows 7. The solution turned out to be disabling the Dell radio control device (name not 100% correct). This loses the ability to use a quick FN-Radio key to turn off all radio devices, but GPOs seem to work OK.

Sorry to drag up an old thread, but my question is somewhat related. Can the Meru firewall be set up to only allow a client to use it's DHCP-assigned IP? Question comes up as our web filter relies on IP addresses and students can change their IP manually (BYOD & student-owned Chromebooks) & try to find one in range that's still authenticated as someone else but currently unused and cause mischief. I thought this may be possible as the Meru WiFi is already inspecting DHCP packets for client type identification.
