If you have a smartphone, you can pick up an app that can perform the same function, but with a few additional features. Aptly named Wifi Finder for the both Android and IOS platforms not only allows you to scan for hotspots, but also gives you access to their database of over 830,000 mapped hotspots in 145 different countries.
Not only is it illegal to access networks without authorization, but it probably would NOT be a good idea to just use your next-door neighbor’s wifi. You want to make sure that you don’t use internet connections that you might be peripherally connected to. The obvious place for investigators to look would be the neighbor, you. For obvious reasons, don’t use the internet connection at your office or a family member’s home.
You also want to avoid using several different hotspots that would essentially triangulate or create a pattern around your residence. Try not to settle into any repeating pattern that could give you away. For instance, don’t settle into using the same coffee shop hotspot every Thursday during your lunch break. Someone could simply stake out the site and wait for you at the appropriate time.
If you don’t choose an off-site connection spot wisely, you may end up leaving behind some easy clues and you might as well be using your own home internet connection. Be careful!
