Broadband Security party deux: So, how DO I get secure?
 

The first thing you need to do is log into your router. For my examples, I will be using a LINKSYS router, which is one of the most popular brands today. LINKSYS routers come with a software package to help you get them setup. Because of this, often people do not know what IP address their IP address is or, more importantly, the IP address of their router. There is a simple way to get his information. I most windows operating systems, you can open a command prompt window and type the command "ipconfig" to get the information you need.
