I am in the process of moving (into the city) and we are cleaning out the house etc. I have noticed a wifi signal that is obviously from a neighbor. The houses are not that close together and I think it is the house across the street with the wifi. I was wondering if there was any free app that allows you to find the approximate direction of the router. Second question: Can I use this internet since it is not password protected? is it illegal, immoral? If not I was thinking about taking my airport express and boosting the signal. Could this be done? I may just tell them they have an open internet connection and they need to put a password on it. Whatdayah think?
