hi all, i am very interested in wifi hacking but there is a funny thing about a wifi network that i hacked once:
so there is a company in my country that give routers but they are ONLY "wep" so wep is easy to hack so i hacked this network with backtrack 5 so after few month i don't how but this person notice that someone hacked him so here is the funny thing, he changed his name and he is wpa2-psk now, how i figure out that that is the same network, his network sometimes do like a glitch a new network appear : Tomson and his old network name appear and he is unsecured at the same moment that network with the new name disappear and after few seconds his old name disappear and the new one appear so can anyone tell me why is that happening and btw when i do a search with backtrack 5 his old name appear but when i put the bssid in the "airodump-ng -c(chanel) -w wep --bssid (his bssid) mon0" in the terminal appear his new name.
i hope i didn't f**k your heads with that just can anyone can explain wtf is happening ?
