The logs are Values read by technicians from the internet provider end, since the logs are what the coaxial cable transmits and the log screen on the router is the translator so can be easily read by them, the coaxial cable is owned by the Internet service provider, I wouldn't be able to tell you what that means.

If your Event Log is reporting a high volume of errors, this would indicate a potential CMTS signal issue. To troubleshoot these errors, we would like to note the current signal levels being used by your (G34). To check the cable signal level on the interface or GUI please follow the steps mentioned on the below article.

we are checking here is the way the signal comes from out to inside the home. There are some important things that should be within a specific range in order for the internet to work properly.

First, the SNR should be above 33 on all of them. The downstream power should always be between -15 and +15. The closer to 0 the better connection. Finally, your upstream power should always be between +45 and +51

On all of those values you should not have more than 3 decibels (or dB) between the lowest and the highest

By having the values in less than that, your device will have interrupted connection, slow or no connection at all.

Thank you for your REPLY. This is what I have now

pages 1-4 and here is the upstream

I believe thse are all within your acceptable levels. Since this original post I have moved the router to the middle of my house (I think I may have had a neighbor that was causing issues with their wifi. As well asadjusted some of the settings. Including creating a second network for my sons  gaming computer and isolated it in case of attacks. I have almost eliminated all of the disconnects; going as long as 3 days without disconnect on all devices except when there was an issue w/spectrum (Apparently they are upgrading or something) I see their trucks out alot! BUT my “Work Computer” still loses connection on ethernet. *And I have changed the ethernet adapter, reset driver adn used different cords as well, just wish there was  a way to figure out what is happening. So I can try to fix it.

Thanks for sharing the cable signal levels. Checking on the Upstream and Downstream levels the Power levels and SNR are on the acceptable levels on both Upstream and Downstream.

As you had already done certain troubleshooting steps, would recommend trying with different ethernet cables if still the same, contact your ISP (Internet Service Provider) and try doing a Re-Provision on the modem.
