So I have been using this router with a netgear modem for a couple months now and all of a sudden it started having issues where it would just disconnect everything on the network

These are some of the logs I managed to get off the router that coincide with the time of the outage. It happens for about 15 seconds then everything begins to reconnect. The other night this happened so rampantly I could not even play a full game online. I have tried resetting the modem and router several times. I have also downgraded to the previous version and that seemed to work for the rest of the day and part of today then it just did it again. I have turned on ipv6 and I am just at a loss idk what else to do. If anyone can please help me troubleshoot this it would be much appreciated. Also I have contacted my isp and they say everything looks normal and they don't see any issues on their end and since it is my own modem and router they refuse to assist further.
Don't worry about the DoS attacks, they won't be causing it. Checked the IPs, it's Facebook and Spectrum (who I assume is your internet provider).
How often does this occur on average? Once a week/day? Multiple times per week/day? Set static IPs for your devices and see if that resolves it please.
It ended up being a corroded coaxial cable line that was causing not enough power upstream. ISP sent out a tech to replace the cable since then everything has been perfect
