How to Find Out If Someone's Been Stealing Your WiFi.

You can't stream YouTube videos fast enough. Instagram photos take time to load. And then it strikes you, someone apart from you is using your WiFi. Well, that's just dandy, innit? You know there's a digital thief lurking about but how do you find out? You use a nifty little app called Wireless Network Watcher. It shows you the number of devices connect on your network. It even lists their IP and MAC addresses and to make things easier, it even shows the make of the device. So the moment you find some devices you don't own connected to your WiFi, you'll know someone's been mooching you off. All you have to do after that is just change your WiFi password and then just stream YouTube videos in peace.
