manyu882 SG nope... its illegal u if a adapter can sniff it, it breaks the 802.11 wireless rules. there is a guide for MAC to do it.. for windows.. harder...
manyu882 SG depends la... u use it to sniff data den decode,network password, credit card password, mac id , or invade someone's privacy etc etc.. is illegal. however, if u sniff it to check the quality of packets in the air, den its legal.
ndmmxiaomayi SG LOL... like that all break rules liao... All wireless adapters have this capability... But if sniff packets to break encryption, then it's against the laws.
