DHCP, Dynamic Host Configuration Protocol, is the protocol used by Internet routers, switches and other networking peripheries to get the Internal Protocol (IP) address for a router or computing device in a network environment. The overall idea behind DHCP is to reduce the amount of manual networking configuration that has to be accomplished when plugging devices into a network and removing them. Sometimes, however, the configuration of your DSL modem will require you to configure the associated wireless router without DHCP enabled. Other times, due to the nature of the operation of the networking device whose IP address changes frequently (like some routers and firewalls), DHCP should not be enabled. Disabling DHCP is a standard operation across router manufacturers.

Difficulty: Moderate
Instructions

Things You'll Need:

  • Broadband router Ethernet cable
  1. Step 1

    Connect your computer or laptop to the router with an ethernet cable.

  2. Step 2

    Connect to the router gateway IP address in your web browser by typing that address into the web page URL text field. The gateway address is listed in your router's user manual, and can also be found by doing a web search on the brand of router. For example, the default gateway IP address for the Telus router is 192.168.1.254.

  3. Step 3

    Select "Home Network" from the top menu and click the "Advanced Settings" tab.

  4. Step 4

    Enter the password to log in to the router if you previously set it when setting up your wireless Internet. If you did not, the default password will be found in your user's guide or on the Internet. Common default passwords are "admin," "password" and "password1."

  5. Step 5

    Select the "Configure Manually" radio button and enter the IP address and subnet mask settings for your router. These will be listed on the paperwork you received from the telephone or cable companies that provide your DSL or broadband Internet. If there is no subnet mask provided, leave it blank.

  6. Step 6

    Uncheck the check box that is labeled "Enabled DHCP" (if it was selected) and click "Save."

  7. Step 7

    Unplug the ethernet cable from the wireless router and computer, restart the router and re-connect to it as you normally would.
