Hard reset instructions for Netgear CM500

If your CM500 router is not working as it should, dropping connections or not being responsive, you should first do a reset of the router to see if the problems persist. Other scenarios where you might want to reset your router is if you've forgotten the password or misconfigured it and can't get access anymore.
Your can reset your Netgear CM500 in the following way(s):

With the reset button

1. Have the router powered on (if just booted wait around one minute for it to load)
2. With a sharp pen or paper clip, press down the Restore Factory Settings button and hold it for about 7 seconds
3. When the power light starts to blink you can release the reset button and wait for the router to start up
4. The power light will be solid (not blinking) once the router is started.

The 30-30-30 reset

1. When router is powered on, press the reset button and hold for 30 seconds. (Use a paper clip or something sharp)
2. While holding the reset button pressed, unplug the power of the router and hold the reset button for 30 seconds
3. While still holding the reset button down, turn on the power to the unit again and hold for another 30 seconds.

This process usually works for resetting any router to it's factory setting. If that doesn't work be sure to check out the questions and answers incase someone else has had similar problems resetting their router.

Note: It is worth reading more about how to reset routers with the 30 30 30 reset and what the risks and considerations are when resetting your router this way, instead of just rebooting it.

How to login to the CM500

To login to the DOCSIS 3.0 16x4 High Speed Cable Modem and change the settings, you can follow these steps:

1. Make sure you are connected to the router's network, either by Wi-Fi or ethernet cable.
2. Open your browser and visit http://192.168.100.1
3. You should be prompted with a login dialogue.
4. Enter the username: admin and the password password
   Note: If you have already changed the password use that instead.
5. You will now be logged in. If you haven't yet changed the defaul password, we recommend that you change it first thing you do after logging in.
