Common Network Troubleshooting & Information Gathering Commands

There are a few things that every basic internet user should know about their network and how to find information. All of these are used in the command line, which you can reach by clicking on Start->Run (Windows) and typing “cmd” then pressing Enter. On other systems, it is usually called the “terminal.”


One command is ping, which allows you to check your internet connectivity by sampling the time it takes to send/receive packets between you and a destination (example: try typing “ping google.com” in your command line). If the ping test “times out,” you are not connected. There are also various other network troubleshooting methods associated with the ping command.


Another example is tracert (type “tracert google.com” in your command line); this command tracks your internet signal through it’s “hops” from host to host between you and the destination, allowing for additional troubleshooting to pinpount connectivity issues. Sometimes your signal, believe it or not, goes from your home to the west coast, to the east coast, and then on to your destination.


For more advanced network troubleshooting and information gathering, the ipconfig command is used. This can tell you all of the information about your network, like IP address, DNS servers, etc. ApexCCTV has demonstrated this technique in one of their videos: “Finding your Default Gateway or IP Address.” Check it out below.

    2. Yeah, no kidding… what’s with my tracert bouncing way far away before it goes to google or what-not… I mean, I know the internet is nothing but a system of long hollow tubes with gnomes running back and forth, but that sure explains why i don’t get the fastest connection.
