Common Problems and Solutions

1. I don’t hear a dial tone, and the Phone 1 LED is not lit.
Go through this checklist until your problem is solved:
• Make sure the telephone is plugged into the Phone 1 port.
• Disconnect and re-connect the RJ-11 telephone cable between the Router and telephone.
• Make sure your telephone is set to its tone setting (not pulse).
• Make sure your network has an active Internet connection. Try to access the Internet, and check to see if
the Router’s Internet LED is lit. If you do not have a connection, power off your network devices, including
the Router and cable/DSL modem. Wait 30 seconds, and power on the cable/DSL modem first. Then
power on the Router and other network devices.
• Verify your account information and confirm that the phone line is registered with AT&T.
• If none of the above works, contact AT&T at 1-866-596-8464.
2. The Status - Voice screen of the Web-based Utility says that the registration for my Internet phone
line has failed.

3. I reset the Router to its factory default settings. How do I configure the settings for my Internet phone
service?
If your Internet phone service account is active, the Router will automatically download its Internet phone
service settings once it is connected to the Internet again. If you do not have an active Internet phone service
account, visit http://www.att.com/linksys to sign up for a new account or activate your account. Then
follow the on-screen instructions.
