Speed issue with Orbi and Nighthawk modem

[Clarkh1026]

I hope this makes sense. Recently I noticed my Orbi RBR850 max download speed on a speed test was under 100mbps. I have gigiblast with Cox. In the past I was pulling 800-900mbps. I have tried rebooting, factory restoring, having Cox come out and nothing changed. I have a nighthawk modem and noticed the Multi gig light is now amber. If I connect directly to my laptop or my old Linksys velop the light is white again and download speeds are back to 800-900mbps. I called tech support and got no help. Firmware is updated and nothing has changed to my setup.

Any ideas? Thanks is advance.

No sense at this point. 

What Firmware version is currently loaded?
What is the model# of the Internet Service Providers modem/ONT the NG router is connected too?

What CAT# lan cable are you using between the modem and RBR and RBR to wired PC? CAT6A STP is recommended between the ISP modem and RBR if the modem supports 2.5Gb connection rates.

The firmware is 4.6.3.16
The modem is my our modem Nighthawk cm 2000

The cable is cat6a.

Here is a picture of the multi gig light on the modem I’m talking about. It’s white right now because I am directly plugged from the modem to my computer. When I plug in the orbi it changes to amber.

What is the connection rate seen on the PC with the CM modem? 1000?

When you connect the RBR to the CM2000, what connection rates do you see on the RBRs statistics page? 

You should see 2500Mpbs:

You should see same as what I see with mine on the WAN port and the multigig LED on the modem should be BLUE:

This is what I see on the orbi

And the light is orange

So you see 2500Mpbs on your RBRs Statistics page?

Try swapping LAN cable between the modem and RBR.

Power OFF the modem and RBR for 1 minute then back ON with the modem first then RBR after wards.

My WAN is at 100 on there. I went to WAN setup and here is the settings.

[Clarkh1026]

No 100 on my Rbr page. I swapped cable and reset like you said. Same results.

[FURRYe38]

Post the RBRs Statistics page please.

[FURRYe38]

Have you swapped the LAN cable for a different cable between the RBR and modem? 

[Clarkh1026]

Yes. No luck. I read another thread where guy WAN was stuck on 100. Doesn’t appear to get resolved. Warranty expired today on mine too.

Might try updating to v.2 on the RBS first the RBR lastly. I would do with this with the RBR disconnected from the RBR. Power off the RBR after it's updated for 1 minute, then back ON. Then factory reset and setup from scratch. After you get to the home page, connect the RBR to the ISP modem.
