Reset a modem by pressing the reset button or by power cycling the unit. No special tools are needed for power cycling, which entails unplugging the modem and then restoring its power, but pressing the reset button requires a small, narrow object such as a pen tip or paper clip.
- Press the reset button
Locate the reset button on the back of the modem. It's typically set in a round hole measuring about 1/4 inch across. Use the tip of a paper clip or pen to press the button. Power cycle the modem if the reset button doesn't restore proper function.
- Power down the modem
Turn off the computer. Remove the power cord from the back of the modem. If the modem has a router, remove the router's power cord, too. Keep the units unplugged for at least 10 seconds.
- Restore power
Plug the power cord back into the modem. After the lights stop blinking, plug in the router's power cord. After the router's lights stop blinking, restart the computer.
