Respuesta: Re: ettercap sniffing
Actually, for unsecured / WEP encrypted wireless networks that's not necessary. You just need to stick your card in monitor mode so it captures all packets. Since everything goes through the air, you don't need to be connected to receive the packets, as otherwise you wouldn't be able to crack networks.

You can even record (capture packets) what they say and then decrypt it later when you learned Mandarin (found the WEP key)
ARP poisoning is used on Ethernet (wired) networks, so you force the traffic to go through your connection.
