XR1000 the cable modem is scanning for a downstream channel.
All,
A new issue has come up. I noticed last night that the internet was getting bogged down. Went and looked at the Netgear cable modem and the downstream light was blinking. I tried to reboot it from my end. It would work for a bit and then start blinking again. I got ahold of ISP and they directed me to plug directly into modem to see if it would stop blinking, which it did. So it looks like something between modem and router is causing an issue.
ISP COX gigablast 1000 mbs
Cable modem Nighthawk CM2000
Router XR1000
QOS set to never, traffic pri off
geo filter off
adblocker off
netgear armor off
speed test 189 down, 37 up ping 8.17, jitter 1.36 packet loss 0% (losing internet somewhere)
I have tried changing channels and rebooting both modem and router. Rebooting works for a few minutes and then downstream error occurs again. Also getting missing JSON when getting onto router login. I am sure its a setting somewhere that is new to me that was not on the XR500. Any suggestions.

The front panel from what I understand the downstream is not supposed to blink. My modem has never done that ion the past.

Bogged down, meaning I have COX gigablast 1000mbs and I am getting roughly 90 mbs on ethernet or wifi on several different devices. If I reboot modem/router I will get 980mbs for a few minutes. Light on cable modem will be solid at that point. Once its starts blinking I go back to 90mbs.

Please post a copy and paste of the CM200 modems connection status and event log page.

I keep putting in password for modem and nothing happens.

I tries edge, chrome and firefox. All say not secure. I even allowed and once i put in password nothing happens. The cable between modem and router is a cat6. The ethernet cable that comes with the XR1000 is a cat5e.
