Actually I don't think it is possible to prohibit wireless networks from laptops, since some laptops come with their wireless card built in, what more, I do believe that one should concentrate most of the efforts in finding the solution on one's network, and not on the clients side to solve such problems. How about creating a separate LAN for mobile devices? which will be heavily monitored and limited in it's services (maybe even wireless :) ) and require port authentication on every switch on you're LAN (IEEE 802.1X) so that you'll know who's connected where, and the laptop computers will be forced to that "special" LAN, on which you may restrict and monitor traffic easier.
BTW, in my opinion, USB mass storage devices (disk on key etc...) pose a higher threat than Laptops. :)

Hi gang! Here is a question for you... We have a secure network with no wireless connections whatsoever. One of our laptop came in with credentials to log on to the network through the Ethernet cable BUT the person had just added a wireless card to his laptop. This situation actually came up and the person could see external wireless networks (from other companies around our building) and access Internet through there. Yeah I know they're stupid, but it's the real world! This seems like a potential threat for taking ourdata out the back door. Copy files accessed through our network toanother network and voilà! No trace at all of the mischief. We monitor internet access and block non-company Email (Yahoo, Hotmail etc.). Suggestions? Thanks and Happy Holidays!
