HAHAHA..... Well your picture is even more confusing as the arrow is pointing out to the internet. I don't see what the big deal is. Connect to the AP, turn on tcpdump and wait until the first computer connects and see what its IP addy is, most likely the .1 of that block is the gateway but if its not do a quick ping sweep followed by a scan and find the gateway,
lol, really funny, i know i am really noob
Test it with: Kismet but no luck
Than i test with:
airtun-ng -a 00:12:0E:82:AA:3D -w 1238050983 wlan0 & sleep 3;ifconfig at0 up
tcpdump -i at0
but no luck.
Can u say what i make bad.
Do a search on netdiscover
that might help you out.
