How do you determine or detect if such people are actually taking advantage of your Wi-Fi connection? One of the simple things that you can do is check out your wireless network connection and see if it is in a secure setting. When you install your router you're given the choice of setting a WEP key. This is a password-protected procedure for you to log on to your Wi-Fi. Now, if you have forgotten to ask one, your Wi-Fi is in an open network setting which simply means it is you who are inviting them to joy ride. This also means that anyone within your connection's range will be able to connect and use your connection. Thus it is imperative that you have a WEP key to deter squatters and joy riders of your connection.
