Use the RG as a modem

Before we move on, we need to change our router's WAN (Internet) connection IP type.

Generally speaking, if you had DSL before, your WAN type would be PPPoE that requires an user name and a password; On the other hand if you had Cable before, your WAN type would be Dynamic IP (DHCP-Assigned).

If you had Cable, or your current WAN type is on Dynamic IP (DHCP-Assigned), then you are good to move on. Might just well double check before you move on so we don't get confused.

If you had DSL, or your current WAN type is PPPoE, you might want to change your WAN type to Dynamic IP (DHCP-Assigned), refer to your router's manual to change it.


Like mentioned before, this method provides most flexibility and preserves all your previous settings including your wireless network and firewall settings. So you don't have to completely abandon your investment and manually enter all your settings into the RG.

Advantages: Preserves all your existing settings; Not limited to a 802.11g network infrastructure if you have a better wireless router/AP; Provides flexibility.

Disadvantages: Can be troublesome for beginners; requires some knowledge of networking.

Let's get started. First off all, let's take a look at the back of the RG (not to scale):

Also let's look at the back of the wireless router. Note: this is just an example to represent MOST of the wireless routers in the markets right now. Most of them look identical in terms of connectivity they provide.

You don't have to turn them off during this process. However after certain steps you might need to power down and up the wireless router to refresh the settings. Of course it's just an suggestion, you don't have to.

  1. Using a network cord, connect the "Broadband WAN" port of your wireless router, to one of the "Ethernet LAN Ports" on the back of the RG.
  2. Using another network cord, connect a computer to one of the "Ethernet LAN Ports" on the back of the RG.
  3. Once connected, use your browser and go to this address:
  4. The AT&T U-Verse RG settings page should show up.
  5. Click on the "Home Network" on the top:

  6. Once there, we need to disable the RG's wireless network. On the right-hand side of the page, you should see a box named "Status at a Glance". Click the "Disable" button right next to the "Wireless":

  7. If you had set a system password, please enter it.
  8. The RG will ask you if you want to disable the Wireless, click "Confirm".

  9. When the "Wireless" light on the front of the RG is off, that means the RG's wireless network has been successfully disabled.
  10. You will be redirected back to the "Home Network" Page. Okay here is where it gets a bit tricky. On the left-hand side of the page, you should see "Local Devices". In side that there is a list of what devices that are connected to the RG.

    In my case, I have the TV set-top box connected to the RG. As you can see here, it showed both my wireless router and the set-top box. However the set-top box is in IP form and my wireless router is in the NetBIOS name form.

    You need to figure out which one is your wireless router. By default, the new wireless routers will have it is model name listed in the "Local Devices" since RG is smart enough to learn it. Of course, if you know your current computer's name or IP address, you can easily figure out which one is the wireless router.

  11. Find the corrosponding device that is your wireless router, click on the "Edit firewall settings." You might need your password again just in case.

  12. This will take you to the "Firewall Settings" page. There you will see a box next to the "1" with a circle, do make sure the currently selected is your wireless router.
  13. Scroll down, you will see three options under the "2" with a circle. Select the bottom one that says "Allow all applications (DMZplus mode)" and click "Done"

  14. Once complete, the RG will show you a short comfirmation page, something like this:

    If you click on "View Details", it will show a more detailed page about the change. Again, do double check if the "Device" is your wireless router.

  15. Now you may close the browser on your computer.
  16. Power-cycle (means power-off then power-on) the wireless router. Or you can manually release and renew the WAN IP directly from the wireless router from a computer that is connected to the wireless router.
  17. Plug your computer back to the wireless router and try to open a webpage. If it opens that means you are done here, if not? Check out the Troubleshoot
