We picked one network at random, associated with the access point, and immediately received an IP address from that network's DHCP server. Since the SSID was set to the manufacturer's default, we decided to play a hunch. We pointed our web browser at the IP address of the router, and discovered that whoever installed the wireless router hadn't even changed the default password. Not only were we into their network, we could have changed the router configuration. We were able to surf the web using their Internet connection. And if we had really put a little additional effort into it, we could have discovered additional information about their internal network. However, we were more interested to see how many wireless networks we could discover, not how deeply we could get into them. We discovered that we could identify wireless networks inside buildings at least 6 blocks away.
