If you do not have a password on your Wi-Fi then I comm and that you must go do it immediately. The Toronto Star shared a story of the damage that can be caused when someone uses your internet connection.
Don’t wait until you get an outrageous internet bill or worse. You are unlikely to know if someone is piggybacking on your signal. Your internet speed may slow down but lets face it you are not monitoring the speed of your internet 24/7.
Your password should include numbers, letters and symbols. Don’t make it easy. Think of it as locking up your valuables in a safe. As the story in The Star illustrates, it doesn’t take long for people to assume you are the worst of the worst.
