DSL service from AT&T can give you fast, reliable and inexpensive access to the Internet, but the technology is not perfect. A DSL modem may lock up from time to time as the result of a hardware conflict or software error. Resetting your AT&T DSL modem will usually solve the problem, but just pressing the reset button doesn't always do the trick. Learn how to troubleshoot and fix a non-responsive DSL modem and get your AT&T Internet connection back up and running.
Turn off the modem, if it is currently on, by pushing the power button. Wait two minutes and then push the power button again to turn the modem on. Once the device has booted and initialized, the LED indicator lights should be a steady green. Proceed to Step 2 if this is not the case.
Locate the reset button on your DSL modem. Depending on your model, it may be on the back or bottom of the unit. Look for a small pinhole, possibly labeled "Reset." Insert a straightened paper clip into the hole, push in and hold for a few seconds and then release. Your modem will reboot.
Launch a Web browser and type http://192.168.0.1 into the address bar. Press "Enter." The modem configuration page will appear. You may be prompted for your modem serial number, which can be found on the bottom of the modem.
Type your AT&T DSL username and password into the text fields. If the modem does not accept your input, enter the default login credentials by typing "admin" for the username and "password" for the password. If you are still unable to log in, refer to the documentation for your modem.
Click the "Connect" button at the top of the page.
Watch for a message at the top of your screen confirming that you are connected to the Internet. Type any URL in your browser's address bar and press "Enter" to begin using the Internet.
Access the AT&T self-support tool, usually found on your desktop or in the Windows Start menu. Follow the on-screen prompts to troubleshoot and repair minor problems with your DSL modem.
