This article will describe how to find out some basic information about your network. This should be the first step before beginning to trouble shoot your network. Without any of this information you will not be able to fix your home network, regardless of how hard or often you hit the router. Again before proceeding please read the article here on some of the terminology and acronyms used in the field
Let's get started:
Open the command line.
Windows: You can do this by opening start and searching for it by typing "CMD", or by simply pressing the "windows button" on your key board (Between Ctrl and Alt on the left side) and the "R" key at the same time. This will open your run prompt. Type "CMD" and hit enter. A small black window should appear.
MAC/Linux: All Linux distributions are different, meaning I cannot give you a sure fire way to open your terminal. For MAC users, you should be able to open search light in the top right corner, search for "Terminal" and hit enter. Linux users should continue to use the MAC section as Linux and MAC use most of the same commands.
Run the command to display current IP information.
Windows: Type "ipconfig /all" to display this information. Whichever interface you are using to connect is the one you will want to pay attention to. It should also be the only one that has any of the data populated.
MAC/Linux: Type "netstat -rn" to display this information. This should print a few lines to the screen.
Copy down your needed data!
Windows: Below is a picture of what windows will display. The first red box is your MAC address, the second is your IP address, the third is your default gateway. The second two boxes are the ones that are important as the gateway is something you'll need to access and configure your router.
MAC/Linux: Below is a picture of what MAC and Linux will display. The only red box illustrated here is the default gateway, again this is the only needed address to access and configure your router.
This completes the tutorial on finding the basic information needed to trouble shoot and configure your network.
