Cox is telling me that my Arris SB8200 is bad, but I don't think the tech was competent.

Question

https://imgur.com/a/jqy8wznImage files of the modem status in the link above.Tech came in, put a simple continuity tester on the barrel connector in basement and declared I have a bad router. I insisted the router is fine (it's a couple year-old Asus RT-AX86U).So then he did some actual testing on the outside line and said all is good. But he did change out an attenuator where the line comes into the basement, is barreled together, and runs directly to my modem. He said it was the wrong attenuator for the service.I have whatever the top package is... gigaspeed or something like that.When I first had an issue last night, I was getting 800 download speed, and only 1.5 upload. Although today when I checked, before he came, I was getting 800 and 40. After he left I am getting 670 and 11.His contention is that the modem is fluctuating and needs to be replaced.I feel like he was initially being lazy and didn't want to do any real testing.... so I am still not confident in his conclusion. What say you?

As we understand that there is a drop on the download speed varying from 800mbps to 670mbps on download so to check if the modem is working properly please connect the modem directly to a hardwired ethernet port laptop or computer and check the cable signal levels .

I’d be better on an incompetent/lazy tech too. Your levels are all over the place, out of spec, and you have a ton of errors. So either the modem is bad or the line is. I’d be betting on the line.
