It might be the season for giving, but that shouldn’t include Unauthorized access to your office’s Wi-Fi network.

It might seem a bit old-fashioned to be worried about giving away wireless Internet. But what if your office is running on a data cap? Those unauthorized megabytes can add up quickly – and expensively.

And there’s another thing to consider here: security. Giving any moderately skilled computer operator access to your wireless network is not much different than sitting them down at your computer with a list of your passwords. (And let’s face it: Most of us aren’t as diligent about creating strong passwords as we should be.)

Last year, we ran a series about basic networking information that you can review if you’re unfamiliar with Wi-Fi. Today, we’ll discuss how you can tell if someone is using your Wi-Fi and what you can do to fix it.
