Hard reset instructions for Netgear Nighthawk AC2100
If your Nighthawk AC2100 router is not working as it should, dropping connections or not
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 Nighthawk AC2100 in the following way(s):
With the reset button
- Have the router powered on (if just booted wait around one minute for it to load)
- With a sharp pen or paper clip, press down the Restore Factory Settings button and hold it for about 7 seconds
- When the power light starts to blink you can release the reset button and wait for the router to start up
- The power light will be solid (not blinking) once the router is started.
The 30-30-30 resetIf the above instructions don't work you can always try the 30-30-30 reset as follows:
- When router is powered on, press the reset button and hold for 30 seconds. (Use a paper clip or something sharp)
- While holding the reset button pressed, unplug the power of the router and hold the reset button for 30 seconds
- 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.
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.
