In order to configure the router with a static IP address, you will need the following information from your ISP:
* IP address
* Subnet Mask
* Default Gateway
* Domain Name Server (DNS) addresses

Access the Router's web based utility by typing http://192.168.1.1/into your web browser.

A password window will appear.
Type in your username (admin) and enter the password (empty)

Click OK.

Once on the Setup page, go directly to the WAN IP Address or WAN Connection Type, and change the option from Obtain an IP address Automatically to Specify an IP Address.

Enter the IP Address, Subnet Mask, Default Gateway, and DNS you retrieved from your ISP.

Scroll down and click Apply.

If settings are successful, click Continue.

The Router is now set up for use with your provider and a static IP address.
