Have you tried using google, or searching these forums yet?
There is an abundance of information on how to do this out there.
I have a computer connected to my wireless network router and i'm not trying to acces to someone else wireless network or do any illegal thing. Then from other computer connected in to another wireless network i try to find out how can i scan and connect to the first one passing trough the router. I'm looking for information about how the router works, not how to crack wep/wpa keys.

Well, it's tought to scan victim bypassing the router. Try the reverse TCP exploit.
