C3700v2 - firmware on admin screen is later than the latest version offered by Netgear?
I've been having constant issues with this device for over two months now. The device will encounter connection issues at odd times and usually reboot itself 2 - 3 times a day. It seemed to happen ev...
The service provider had to make three trips out to my residence but they eventually replaced the entire line and the connection has been consistent. Appears it had nothing to do with the firmware.
If anyone encounters this in the future please be sure the technician inspects the line inside your house, outside to the pole, and also across the road if your line warrants that. The first tech replaced the line from our house to the pole and declared success. We had signal issues 30 minutes after he left. The second tech found signal issues and shorts with the line from the house entry point to the modem so he re-did that and declared success, and then we had signal issues 30 minutes after he left. The third tech found signal issues in the cable leading from the bup pole across the street to the main pole, so he replaced that and the splitter box where all the other neighbors tap in. I'm not sure how you ensure the tech does this because they'll get offended if you scrutinize their work, but I just wanted to stress the importance of a comprehensive analysis of the entire line.
You have errors and criticals that the ISP needs to review and help resolve.
Please post a copy and paste of the modems connection status and event log 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.
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.

Any idea why there's a TFTP transaction? Is Cadant MAC affiliated with a category of device, such as those used by an ISP?
when the modem side boots up, it checks its provisioning that it got from the ISP/CMTS. It could be using tftp for checking/confirming your settings. But you are having line issues and need to check your line and potentially have your isp check it.

If you can, simply connect the modem right where the coax comes into the home. This prevents wiring in the home from being the issue. And some ISP’s charge if the wiring issue is in the home. So this helps prevent this.Line would not be an issue. I was experiencing issues previously (https://community.netgear.com/t5/Cable-Modems-Routers/C3700v2-firmware-on-admin-screen-is-later-than-the-latest/m-p/2241857#M39107) and my SP found cable shorts and signal drops and then replaced the entire line all the way up to the box on the telephone phone where it's split amongst neighbors. The log should not indicate signal strength issues and I appreciate any details on how that is being determined from the log I posted.
There hasn't been an issue for a few days now so I'll post logs if anything more happens.
Your log does indicate line issues.
It could be the line from house/pole, it could be the connections when they replaced them, it could be the cmts that its connecting to. But your logs are still indicating issues.
