Let's say that several of your neighbors have wireless networks and that these networks are insecure. Do you think it is unethical to connect and see what's on the network? How about if your network goes down and you want to determine if it is either you or your server. Is it okay to connect to your neighbors network merely to see if you can ping yahoo.com? I suppose it would depend a lot on the type of relationship you have with your neighbors. Any opinions?
