AT&T U-Verse is a feature that allows customers to subscribe to phone, cable and Internet service through one package. AT&T U-Verse is delivered through a fiber optic cable line and is connected to an AT&T U-Verse wireless router, manufactured by 2Wire. If you have a disruption in service or a poor wireless signal, you can troubleshoot the problem by changing the channel on your AT&T U-Verse router.
Click the "Home Networking" tab located at the top of the menu bar. Click "Edit Settings" located on the right side panel.
Scroll down to the Wireless Channel section. Select a wireless channel from the drop-down menu. Scroll to the bottom of the page and click "Save" to save the changes made to your wireless router.
Change the channel on your wireless router until you find the channel that provides you with the best signal strength.
