Thanks to wireless routers, setting up a home or small business network is easier than ever. No running cables, no drilling through walls, just plug in, configure, and go. However, it's also easier than ever to hack into someone's network, thanks to wireless routers.

If, when setting up your router, you didn't change the administrator name and password, or if you're still broadcasting your SSID, (or if you don't understand what all this means) then it's possible someone else might leach onto your network and leverage your broadband connection for their own nefarious means.
