Hello.Our modem is working (according to Comcast) but can’t get wifi to work. The Orbi has the purple color. I’ve attempted power cycling 5 times (per this https://kb.netgear.com/19755/How-do-I-power-cycle-my-home-network) with no luck. What else can I try?

What Firmware version is currently loaded?What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too? Be sure your using a good quality LAN cable between the modem and router. CAT6 is recommended. https://kb.netgear.com/31030/What-do-the-LEDs-on-my-Orbi-mean Has a power off for 1 minute then back ON with the ISP modem and router been performed since last update?Be sure to restart your network in this sequence:Turn off and unplug modem.Turn off router and computers.Plug in and turn on modem. Wait 2 minutes for it to connect.Turn on the router and wait 2 minutes for it to connect.Turn on computers and rest of network. If your ISP Modem already has a built in router and wifi. This would be a double NAT (two router) condition which isn't recommended. https://kb.netgear.com/30186/What-is-Double-NAThttps://kb.netgear.com/30187/How-to-fix-issues-with-Double-NATCouple of options,1. Configure the modem for transparent bridge or modem only mode. Then use the Orbi router in router mode. You'll need to contact the ISP for help and information in regards to the modem being bridged correctly.2. If you can't bridge the modem, disable ALL wifi radios on the modem, configure the modems DMZ/ExposedHost or IP Pass-Through for the IP address the Orbi router gets from the modem. Then you can use the Orbi router in Router mode.3. Or disable all wifi radios on the modem and connect the Orbi router to the modem, configure AP mode on the Orbi router. https://kb.netgear.com/31218/How-do-I-configure-my-Orbi-router-to-act-as-an-access-point and https://www.youtube.com/watch?v=H7LOcJ8GdDo&app=desktop https://kb.netgear.com/000061277/Which-features-are-disabled-on-my-Orbi-router-when-it-is-set-to-AP-Mode

To add clarity it was working fine before yesterday morning. A storm rolled through and we lost internet (never lost power).The modem is A nighthawk CM2000.Have already tried the power cycling steps several times without fixing it.

What Firmware version is currently loaded? Be sure your using a good quality LAN cable between the modem and router. CAT6A STP is recommended between the RBR and CM modem. Do does a wired PC connected to the CM modem with out the RBR connected to the modem work or does the PC not get internet here as well? Connect 1 wired PC to the modem and power the modem OFF for 30 seconds then back ON. Check for internet services with the PC.

The Ethernet cable from the nighthawk modem to the laptop connected the laptop to the internet. I used the reset button on the Orbi earlier to try to set it up fresh as an option and get stuck at the end - it says a cable is not detected now. I can’t check the firmware version (that I can see) without it finishing the set up. We are using the cable the Orbi came with and had been working since we got the Orbi in February (and connected just now to the laptop fine).

Try swapping cables with another cable.

Be sure to restart your network in this sequence:
Turn off and unplug modem.
Turn off router and computers.
Plug in and turn on modem. Wait 2 minutes for it to connect.
Turn on the router and wait 2 minutes for it to connect.
Turn on computers and rest of network.

Couple of options,
1. Configure the modem for transparent bridge or modem only mode. Then use the Orbi router in router mode. You'll need to contact the ISP for help and information in regards to the modem being bridged correctly.
