Bad downstream signals?

Bad downstream signals?

Hello, thanks in advanced for the help. 

I recently upgraded my xfinity internet service to the 1gb speed. However, I think my downstream signals are very bad which is causing me packet loss and lag. The modem I am using is a Netgear Nighthawk Cable Modem CM1200 and the wireless router I am using is a Netgear Nighthawk Smart WiFi Router (R7000) - AC1900. I will answer any questions you have to the best of my knowledge but I'm just sick of paying all this money for what's supposed to be good service and I get garbage in return.Capture.PNGCapture2.PNG

I don't think the images uploaded correctly so I'll post an imgur link to the photos of the downstream signals.  https://imgur.com/a/AxZVHfc

Re: Bad downstream signals?

Have you ever had a tech out before? What’s your upstream signal look like?

I had a tech out today to replace a faulty cable box and I mentioned to him about my other issue so he tested my COAX cable and ended replacing a splitter and 2 cables and checked the outside box and he still seemed iffy about it. This imgur link is my upstream bonded channels. https://imgur.com/a/H6Jyd6M

You’ll probably need a second tech, there’s nothing iffy about those levels, they’re awful. Upstream is good
