Darn. It is more difficult with a modem router combo(AKA Panoramic gateway). Try going to 192.168.0.1 > User;admin password;password(unless changed) > Connection > Cox Network > Scroll down and look at the downstream and upstream levels. Copy/paste is difficult because of the formatting so if possible, upload a screenshot. Basically your downstream should be between +5 and -5 and SNR above 35. Upstream should be below 50. The bad part is you can't see your logs of when the connection drops.
Also you mentioned the coaxial going to the street was replaced, but could you explain how the coaxial gets from the street to the room the gateway is in? Splitters/filters/amps? If so, how many and what kind?
Single coaxial barrel connector connected to wire straight to modem. no splitters or amps.

What about outside? Do you have a plastic box on the side of your house where the coaxial attaches to your ground? If so, have you looked inside there for splitters? Sometimes a technician will use one for the attachment to the ground rod or however it grounds. Once I see the signal levels I will be able to say what the problem is with more certainty.
Outside there is an Antronix ground block which the service coaxial connects to. My coaxial connects to the other side of the ground block. No other splitters or connectors. Will try to get signal levels if can get internet service back
Which one is the downstream?
See under where it says "Downstream" in blue? Those are your downstream channel signal levels. What is of note is your upstream signal strength. It should be below 50 and it is 59 and only bonding on one channel. This makes me think the upstream has noise/ingress on it and is causing the gateway to reboot. That's why your second screenshot only showed the downstream since it was in the act of rebooting. Noise on the network can come from all kinds of things from a bad drop out on the pole, chewed wires somewhere on your street or even someone with a old TV or VCR hooked up in your neighborhood that is backfeeding electrical ingress into the system. I suggest sending a email to Cox and have them send a inhouse technician to scan your coaxial line for noise. Since you have a direct connection, there should be no charge but double check that with the technician when they are there. The charge is based on how the tech. resolves the work order.
Thanks I'll contact cox in the morning
Hello Jaydownsouth. I am sorry for the service issues you are experiencing. We strive to ensure our service remains reliable and operates properly at all times for our customer's needs. The image you provided shows the downstream section, which is all of your downstream channels being utilized on the modem. At first glance, the levels all look normal. Can you send us an email to Cox.Help@cox.com with your full name and complete address? I would like to investigate this issue for you.
If I send you an email will you investigate mine as well?
