Make AT&T Uverse i38HG access point behave

i38HGWhen AT&T hooks up residential Uverse Internet, it sometimes puts the actual router in a box outside the house, and the box inside the house is just an access point. This can prove problematic to customers who want to install their own routers for purposes such as setting up Unblock-Us.

Because the AT&T Uverse 2Wire i38HG access point and its i3812v router provide only limited settings options at their address, a third-party router may be required. Unlike other home Internet configurations that allow customers to plug their wall cable directly into a router, the AT&T router’s outside-the-home location makes it difficult for customers to use their own routers to manage Internet traffic.

This post will explain how to make the i38HG access point and i3812v router behave more like they’re in bridged mode.

The best way to do so is to follow the instructions found here:

1. Set your router’s WAN interface to get an IP address via DHCP.  This is required at first so that the 2Wire recognizes your router. (On my router, it was configured to get IP addresses via DHCP by default, so I didn’t have to change any settings.)

2. Plug your router’s WAN interface to one of the 2Wire’s LAN interfaces. (The WAN interface is the one that’s labeled “Internet” on some routers.)

3. Restart your router, let it get an IP address via DHCP.

4. Log into the 2Wire router’s interface (by visiting in your browser).  Go to Settings -> Firewall -> Applications, Pinholes, and DMZ

5. Select your router under section (1). (Select your router by finding its MAC address. On a Linksys router, find your MAC address by navigating to in a new browser window, clicking on “Setup” and then “MAC Address Clone.” A MAC address may also be found by looking at the label on the bottom of the router.)

6. Click the DMZPlus button under section (2).

7. Click the Save button.

8. Restart your router, when it gets an address via DHCP again, it will be the public outside IP address.  At this point, you can leave your router in DHCP mode (make sure the firewall on your router allows the DHCP renewal packets, which will occur every 10 minutes), or you can change your router’s IP address assignment on the WAN interface to static, and use the same settings it received via DHCP.

9. On the 2Wire router, go to Settings -> Firewall -> Advanced Configuration

10. Uncheck the following: Stealth Mode, Block Ping, Strict UDP Session Control.

11. Check everything under Outbound Protocol Control except NetBIOS.

12. Uncheck NetBIOS under Inbound Protocol Control.

13. Uncheck all the Attack Detection checkboxes (7 of them).

14. Click Save.

That should do it. Your router will now handle your Internet traffic and settings after it passes through your AT&T equipment largely uninterrupted. For wireless access, connect to your new router instead of the 2Wire access point. I took the extra step of turning off wireless in the 2Wire’s settings, but I’m not sure whether that’s necessary.

  1. Hi. I have a Linksys WRT54G wireless modem. My DSL modem is a Westell 6100. I’m using Windows 7. I’m trying to change my security settings so I can use my wifi with my Nintendo DS. In order to do that, I have to acess my router. When I go to, I just go to my MODEM settings. I can’t figure out how to just get to my router. Also, I need a password and username to access anything on my modem, but nothing I’ve tried works. Please help?

  2. Open web browser and type in the address such as Most of the routers out there listen on port 80 so this should work. If the router is secured with a user name and password provide it at the login screen. If you do not know, consult the documentation for the default username and password, or perform a reset of the device to get the router back to the default settings so you can log in with the user name and password listed in the documentation.

  3. AT&T introduced its U-Verse service in an effort to provide consolidated digital television programming, telephone access and high-speed Internet access to home subscribers, through the use of a single residential gateway. The gateway acts as a combined modem and wireless router. Set-top boxes are required for television sets in the home. Being able to access a U-Verse router with your laptop or other Wi-Fi capable device is essential for enjoying all the benefits that U-Verse has to offer. Here’s how to access a U-Verse router for Internet service or to adjust the settings.
