This is fairly simple and has many uses. If you are using a device that stays on the same network for all of its up-time I recommend you do this.

It is important to remember that settings set can be changed back to default with ease.

Step 1: Step 1: Finding Your Current Settings.

You will need to open CMD (Command Prompt) with Administrator Privileges. To do this open the start menu, and search for "CMD". Then right click on "cmd.exe" and select "Run as Administrator. You will need Administrator Privileges to do this. Contact the owner of the computer if this isn't you.

Step 2: Step 2: Knowing What Your IPv4 Address, Subnet Mask and Gateway Is.

Type "ipconfig" and write down your IPv4 Address, Subnet Mask and Gateway. You will need these for later.

Step 3: Step 3: Accessing Your Adapters

Open the "Control Panel" from the Start Menu, then go to "Network and Internet", Network and Sharing Center and then click "Change adapter setting" on the left panel.

Step 4: Step 4: Opening Your Adapter & and Making Changes

Right click on the Connection you are using and click "Properties", in most cases, it will be the "Local Area Connection". Then double click on "Internet Protocol Version 4 (TCP/IPv4). Ensure the "Use the following IP address" and "Use the following DNS server addresses:" is selected. Using the information from before, enter your subnet mask and default gateway. If this is the first time you are doing this, set the IP to something close to 192.168.1.200, but not below 192.168.1.150. Each device must have a different IP. Your DHCP Server hands out IP's that are not in use. If your PC is off, and set to a low IP, it may be given to a different device. This WILL cause issues. Set the first DNS to 8.8.8.8, and the second to 8.8.4.4. These are run by Google, so you wont have any issues. Then check the "Validate setting upon exit" box and click OK. This will check for errors and help you fix them. There most likely wont be any. Then Click OK again and let the check run and search for errors. Fix any errors or just click close when it is done.
