Reset IP Address of Computer or Router

Reset IP address of your computer or router if you lose connectivity on the LAN or on the Internet. It sometimes becomes necessary to manually renew your computer’s IP address.  If you suddenly realize you do not have an Internet connection, you can often right-click the network icon in the taskbar near the clock ofn your desktop and select “repair.” This will go through a process of resetting your IP address.

But if you do not have this option, you can go to START>RUN and type cmd.

reset IP address

At the command line type ipconfig /release (or winipcfg /release in earlier versions of Windows). Then hit ENTER.  Next, type ipconfig /renew and you should get a new IP address from the router. If this does not help, you will need to login to the router and delete the Mac address entry for your computer.

Reset IP Address of Router

If you have a cable modem, you may want to also renew its IP address.  First, go ahead and release the IP address on the PC, then shut the computer down. Next, unplug the cable modem for a couple of minutes, then plug it back in again. Once all of the modem lights are green, power up the PC again. It should automatically renew its IP at boot.

Note:  If you have a router, you’ll want to unplug it, as well, then plug it back in AFTER you plug in the modem, but before you power up the PC. The router will need to supply the PC with a new IP address.

If the reset IP address option fails to help you regain Internet access, there could be other issues with your computer. You could have a mis-configuration of your network settings that prevents you from obtaining an IP address, or you could be receiving an IP address but you might have malware issues or incorrect DNS settings.
