Nighthawk cm2000 fast blinking all lights

Are you asking a question or just reporting back?

 

Blinking lights are usually a sign of action on a device.

 

Manuals are always a good place to start.

Visit the support pages:

Feed in your model number and check the documentation for your hardware.

Check the section in the manual Troubleshoot With the LEDs.

You may have done that already. I can't tell from your message.

I mention it because Netgear gave up on supplying paper manuals and CD versions some years ago and people sometimes miss the downloads.

 

You have posted your message in the section of this community given over to General WiFi Routers (Non-Nighthawk). (This is easily done, given Netgear's complicated community structure.)

Many questions apply to different types of device, so there may be useful responses here, but you might get more help, and find earlier questions and answers specific to your device, in the appropriate section for your hardware. That's probably here:
