Nighthawk X6 AC3200 R8000 Router- after changing isp plan, the internet light is amber

Hello!
A couple of days ago we upgraded our internet speed plan. Since that transaction, the internet light on the router is amber and we cannot connect to wifi. If we connect devices directly to the router w/ an ethernet cable, we can access the internet. What we have done:
-power cycled both the router & ARRIS modem numerous times
- checked cord connections. Everything is properly connected
-Factory reset the router.
Until two days ago both wifi & wired connections worked well. After the speed plan upgrade, we cannot access wifi. My isp said the signal to the modem is strong & since the router is not their equipment, they cannot help me w/ the issue.
Any help, fixes, suggestions would be truly appreciated. Thanks!

A firmware default reset also resets the Wi-Fi SSID and password.

 

Are you using the firmware default Wi-Fi SSID and password?  They are on the label on your router.

 

If yes, you have to manage the connection on the device you are using to connect, forget the connection, and select the SSID and enter the password fresh.

 

When you power cycle your devices, a sequential power up is often needed to re-establish the connections.

At your modem, power it down, disconnect the power cord, coax, and Ethernet cable.  Let is set.

Go to your router, power it down, disconnect the power cord, and all Ethernet/USB devices.

Back to your modem, connect the coax, power cord, and power up the device.  Give it plenty of time to boot and stabilize before connecting the Ethernet cable.

Connect the power cord and Ethernet cable to your router and power it up.  Give it plenty of time to boot and stabilize.

Thank you for responding.
Yes, we used the ssid & password on the label. We got a pop-up saying "connection without internet."

Followed the sequence you laid out, unfortunately the steps didn't work. The light is still amber and we cannot connect to wifi.

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?

What is the CAT# lan cable between the ISP modem and router? CAT6 is recommended.

What mode is the modem working in? Router  or Bridged? 

Your ISP Modem already has a built in router and wifi. This would be a double NAT (two router) condition which isn't recommended.

Couple of options,
1. Configure the modem for transparent bridge or modem only mode. Then use the NG 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 NG router gets from the modem. https://kb.netgear.com/25891/DMZ-on-NETGEAR-routers

3. Or disable all wifi radios on the modem and connect the NG router to the modem, LAN to LAN configure AP mode on the NG router.
