There are a few ways you can go about fixing this problem. I’ll start with the simplest and move on.
1. Renew IP Address – You can release and renew the IP address for your computer using the command prompt. Read my previous post on how to renew an IP address.(http://www.online-tech-tips.com)
2. Reconfigure Static IP Address – If your computer is using a static IP address, it is best to try and use a different one in the same subnet. One way to check to make sure the one you are picking is not already being used is to simple ping the IP addresss (ping x.x.x.x).
You can read my previous post on how to change your IP address (http://www.online-tech-tips.com) using the command prompt.
3. Use DHCP – If you don’t need to use a static IP address, it’s best to simply choose DHCP instead of manually configuring the IP address. The server will know which addresses are free and which are taken.
4. Update firmware – In some rare instances, the actual DHCP server can malfunction and assign more than one computer the same IP. In this case, it is best to try and update the firmware on your router.
