Nighthawk CAX80 Upload/Download speeds and ping spiking
I just got a AX6000 WiFi Cable Modem Router (CAX80) yesterday and have been getting constant ping spikes in games and such every 30-45 seconds ever since. I am running on firmware v2.1.3.5. I replaced my default Xfi Gateway from Xfinity with this but was having no issues beforehand using the other modem/router combo. When going to 192.168.1.1 in my web browser and looking at my Netgear panel it is showing my cable connection status as poor. When I go into the diagnostic for it everything is green apart from my upstream status which is showing red. I should also add that I am using the same coax cable and ethernet cables that I was using previously so the only thing that has changed is the router/modem itself. Any help would be appreciated.

Please post a copy and paste of the modems connection status page.
Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.
Be sure there are no coax cable line splitters in the between the modem and ISP service box.
Be sure your using good quality RG6 coax cable up to the modem.
Be sure to power OFF the modem for 1 minute then back ON.

https://www.duckware.com/tech/solving-intermittent-cable-modem-issues.htmlAre you wired or wirelessly connected to the CAX when gaming?
There seems to be a problem on 5Ghz wifi:
I am not sure if this is what you are reffering to or not, I also have a technician coming out on Saturday to look everything over.

I'm seeing some correctables on the down, and some on the UP link. Something the ISP needs to look into. These should all be zero.
Be sure when you ping and speed testing, that your using a wired PC connected to the modem. Ensure you don't have any background running apps on the PC running when your testing.
