Security technologies depend on the correctness of the system they're actually checking.
If you look at the 802.1x, they tell you the 1x protocol is insecure when used in a shared medium environment unless a security association is established. Since 802.11 doesn't do that, so by IEEE's own words it is insecure,
This problem exists whether you use WEP or not, but it is trivial to exploit if not using WEP,
would be shocked if they solved the problem.
