CM1200 Intermittent connection issues with WOW cable

I've been having connection issues with WOW cable and my CM1200 modem the last couple of months.  Almost every afternoon the connection drops and then intermittently drops the rest of the evening.  Is it time for a new modem? WOW cable says the signal looks good. Cables all seem to look good to me and also only 1 splitter prior to the modem.  Any advice  or support appreciated. 

 

Snip of the logs is attached.

Be sure your using a good quality LAN cable between the modem and router. CAT6 is recommended. 
What is the brand and model of the host wifi router connected to the modem?


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.

Cable connections screenshot.  Just replaced cable between modem and router with a Cat6. Modem is hooked up to Google wifi hub.

Well your power levels are all over the place. Some Higher, some lower. You have correct and un-correcables that should all be zeros. 

Check for ISP coax cabling and fittings and splitters. Ensure coax jack fittings are screwed in well and snug. 

ISP need to check signal up to the modem. Power levels on all channels should all be in the same range.
