One of the general annoyances of connecting to the wireless infrastructure at show like TechEd is the number people that seem to be in my general vicinity broadcasting as an ad-hoc connection. Are they trying to get unsuspecting people to connect to them and gleam some information from their laptops? I doubt it, but still annoying.
From Techedbloggers.net I found a great tip from Chris Pringle about adding a quick filter to suppress ad-hoc networks.
as an admin run the following:
netsh wlan add filter permission=denyall networktype=adhoc
to reverse this again run the following:
netsh wlan del filter permission=denyall networktype=adhoc
