C7000v2 Internet randomly goes out and factory resets on his own
I am looking for some help with my cable modem router. I have a NetGear C7000v2 firmware V1.03.08. I have been having this issue for probably the last 4-6 months.
I have tried trouble shooting with Xfinity, but the issue remains. My internet will randomly go out anywhere from 3-6 times a day, sometimes more. Sometimes it will randomly disconnect and reconnect on its own, but most of the time I have to reset the router. Most of my devices are ethernet like my laptop and Xbox.
One issue that has happened three times already (today being the third), my router will reset back to factory settings and have me re-create an Admin to my router. I'm out of warranty and want to avoid paying $130 if at all possible... I am looking for some help to see if this router can be fixed, or if i truly am SOL.
Not really sure where to begin or what info to share to get started. I appreciate any help as i need to get this fix as soon as possible as I work from home.

https://kb.netgear.com/30008/How-do-I-view-or-clear-the-event-logs-on-my-NETGEAR-cable-modem-or-modem-routerHave 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.
Start with removing any amplifiers, signal attenuators, or splitters from the coax.
From there check the line for kinks, damage, moisture in the line.
Check the connectors for improperly made ends, foil touching the copper coax line, loose connections, bad/old/cheap connectors, or corroded connections. Replace them if you do.
Be sure to power OFF the modem for 1 minute then back ON.

https://www.duckware.com/tech/solving-intermittent-cable-modem-issues.htmlSorry for the months of delay and i appreciate your help. I replaced the coax cable with a new one and also removed the splitter that was added my Xfinity as I only use internet with no cable TV. I thought removing the cable for a new one would fix it, but the issue is still happening.
There's no kinks in the line that I see and the new one is now installed. Removed all cables from the modem and had it completely powered off for +5 minutes.
I can include the event log, but i believe it mentions MAC so I need to blank those out right?Power is WAY TOO HIGH:

Going to burn out the modem eventually.You have a ton of correctables and un-correctables that should be zeros.
Please edit out the MAC ADDRESSES before posting the event log if you see any.
