Does the wifi AP provide for MAC tables?  ie you set up the permissible 
MAC addresses that can connect to the wifi AP.... 

Then only valid MAC listed NICs can get an address from the dhcp server 
in the wifi access point.

While not perfect it certainly 'Makes It Harder' for the 
opportunistic wardrivers to connect as their NIC isnt
'known' in the wifi MAC table.
