The reset button is usually red and can be found on the back of the modem. To reset your modem using the button, follow these steps:
1. With the modem plugged in and powered on, press in the reset button (using a bent paperclip or pen tip) until you feel or hear a slight click. Hold it in for 10 seconds.
2. Release the button when the power light turns amber (orange).
Note that if you continue to press the reset button for 15 seconds, then the power light will turn red and your modem will reboot. If this happens, you will need to wait for it to finish rebooting, then try the reset again.
