How to Renew a Router IP
By Steve McDonnell
The router that serves as the gateway for your company's Internet access requests a public IP address from your Internet Service Provider. The public IP address enables you to send and receive traffic over the Internet. When there is a problem with your Internet service and the router can't obtain a public address, it might assign a private address in its place. When the service problem is resolved, you can either power off and power on the router to renew its IP address or you can release and renew the IP address through the router's setup options.
Launch a browser and access the setup page for the router by typing its local IP address. For example, type "http://192.168.1.1" and press "Enter."
Sign in to the router with an administrative username and password.
Locate the WAN section of the status screen containing your public IP address information. Click the button or choose the option labeled "Release" to remove the current IP address. Click the button or choose the option labeled "Renew" to request a new IP address.
Verify that the new IP address is a public IP address by ensuring that it does not fall within the following ranges: 10.0.0.0 to 10.255.255.255, 172.16.0.0 to 172.31.255.255 and 192.168.0.0 to 192.168.255.255. Contact your Internet Service Provider if the router fails to obtain a public IP address.
You can also power off and then power on the router to renew its IP address.
