Even if you were found out, the most the cable company might do is come out to secure the ladies wi-fi with a stronger encryption type (and that's a really small chance they could be motivated to do that and only if it's their equipment). Someone would have to be on-site to find you out (and they still wouldn't see you, just your traffic and MAC tied to the router) and have to know what they were doing in the first place. Are black helicopters gonna show up overhead because of this, no. The laws don't start really kicking in until you start tampering with the things that are on her network (i.e breaking into her computer). Are you thieving anything from them, not really, you're just using their access point. Is it morally right to use something someone else is paying for without asking, probably not. I'm not sure how you would do that on a PS3 though, perhaps you could use a programmable router that can bridge your neighbors network and have it spoof it's MAC and then feed an internet connection to you PS3 and other devices. This great helps my anonymity on any network I connect to. You can also fake your computers MAC address quite easily, I even have a startup script on mine that generates a random one for me every time I boot my machine. So while what you're doing is technically illegal I'd say there's only like a 10% chance of any negative repercussions. That being said most owners would just up and change their network password, maybe learn a bit about proper wifi security and move on with their lives. From the MAC address the owner 'could' get the police involved and they 'might' track you down if they go to the manufacturer and find out who bought the machine. The MAC address is a unique id assigned to a network device such as the wifi card in your laptop and PS3.

Specifically it stores the MAC address and device name, such as STEVES-MACBOOK. A router keeps logs for a certain period of time of all the devices that connect to the network.
