Hi,
I agree that it is not 100% secure, and creates "a false illusion of security". But how can you secure your Ap. One can crack WEP, change MAC...so if i take a look at client machine, I can make a "copy of this machine" (it is hypothetic of course), and use HIS ISP AP for instance, And tehere is Nothing that can be done to stop me!. I think that if somebody knows how to hack (change) MAC, there would be no problem to Crack WEP and brake the security..I maen it is enough for me to have MAC Filtering only. What do you Think?
