How to Set a Static IP With DD-WRT

Save

DD-WRT is open source firmware that you can install on your wireless Internet router as an alternative to the firmware that comes preloaded. The name comes from a combination of the Dresden license plate abbreviation (DD), where the developer is from, and the router model name that the firmware was originally made for (WRT). DD-WRT offers a number of features that expand the functionality of your router. To take advantage of some of these features, you may need to configure your DD-WRT router to use a static IP address instead of one obtained by dynamic host configuration protocol (DHCP).

Things You'll Need

  • Router running DD-WRT firmware
  • Static IP information, as provided by your Internet service provider (ISP)
  • Open the DD-WRT control panel by entering the internal IP address of your router in your browser's address bar. For example, if the internal address of your router is 192.168.1.1, you would type this address in the browser:

    http://192.168.1.1

  • Click the "Setup" tab at the top left of the main screen and locate the section called "WAN Connection Type" under "WAN Setup."

  • Select the drop down-menu next to "Connection Type" and change the selected option from "Automatic Configuration - DHCP" to "Static IP." This will cause a number of configuration boxes to appear under the drop-down to help you set your static IP address.

  • Enter the static IP information provided to you by your ISP in the boxes below the connection type. This includes the WAN IP address, subnet mask, gateway and at least one DNS server.

  • Scroll down to the bottom of the page and click on the "Apply Settings" button to complete your static IP configuration.

Tips & Warnings

  • You may lose access to the Internet if you enter erroneous IP information, so be sure to double-check your settings before saving them.
