At&T's U-verse package combines cable, satellite dish, broadband and voice over Internet into a bundle. As with most technological advances, there are always a few bumps in the road before near perfection sets in. Most people who have high speed Internet and have wireless capabilities, use a modem and router. The AT&T U-verse 2Wire RG is an all-in-one modem/router/Wi-Fi access point, also known as a residential gateway. There are a lot of settings you can tweak if you access your U-verse residential gateway. You can modify the wireless settings by accessing the 2WIRE setup. This is the method tech support uses if you're experiencing problems with your U-verse service.
Locate your 2WIRE pass code that is located on the bottom of the RG. It is near the area on the barcode where your wireless network key is. Write the pass code down. Then type the following address in the Web browser: 192.168.1.254/mdc.
Once in the program, click the System Summary, then select the "Home Network" tab.
Navigate to the "Status at a glance" area. Various settings, such as your wireless encryption, key, Network Name and channel appear. The default setting for your wireless channel is located there as well.
