Thank you very much!


In other words:


If it is a hub (as most wireless APs are), you can have a duplicate MAC on the network as long as you set your own, 
different IP. Once you have different IPs, you will receive your own traffic, and the original client will receive 
theirs, as packets are routed using the IP address rather than the MAC address.


A switch, on the other hand, routes packets to clients using their MAC address rather than the IP address, so you're 
more likely to have problems in this situation - however, this hardly ever applies to APs, especially SOHO ones (as 
they are hubs).



i think that the routing table of the switch is being taken on the MAC
address until the disconnection of host1.

For example, let's take MAC1 (connected) and Attacker. If Attacker
spoof the MAC address of MAC1, he can try to change it with
macchanger, but he will not be really connected until the other client
will be connected to the AP. So Attacker need to use some
disconnection-tool (aircrack for example) and before that MAC1 try to
reconnect, must connect to the AP with his MAC address.

Is that correct?


Thank you ;)
