Finding IP from SSID

[Far]

Unfortunately networking has never been one of my major strong points, so i'm unsure on exactly how this works.

I have a laptop on wireless, which picks up several virgin and BT routers around my area.

All of these are protected with WEP keys, however as they haven't made their SSID private i'm wondering if its possible to find their external IP address from their SSID name - from this ill be able to connect to their router login, use the generic Virgin media login and password (which 90% of customers don't change) and find their WEP key to connect.

I've got programs such as Network Stumbler, and can be use in conjunction with a port sniffer - unfortunately my current wi-fi adapters are not supported for it so i can't try that method.

I've also got wireshark, however i've never used it before - and am unsure if i actually need to be connected to their network first before i can sniff their packets.

Yes i know i can get the password by breaking the encryption, but i want to avoid that if possible as its very time consuming. All i really want is their external ip - so i can log in to their router.

ive got an app to get past thompson routers, but unfortunately it doesn't work with virgin ones.

It's more curiosity than anything now, i have internet - but i'm wondering if the method im asking if possible.

connect to one network and use nmap on linux to scan range ip around you.. as i think virgin it goes with zones so.. if you connect one wifi, look on nmap for the ntworks around you
