Thanks for your patience! If you've tried everything else and those arrow lights are still blinking, it's time to try a factory reset.
With your modem still powered on, find the Reset button on the back of your modem. Use a paper clip or pen to press Reset for 10 seconds. Give your modem some time to reconnect.
Your modem is ready when the lights are solid (not flashing).
Note: Your lights may not be green like the picture. The color of your lights may vary depending on your modem model.
