Curious. Do you have any wireless cameras on your network? Also, some chat apps can get through. we should talk because I am pretty sure I have a similar issue especially with a certain IP.

I do have (1) Wireless Porch camera. This is one of the locations on my LAN that has dropped off assuming as a result of a DOS attack. Most times now, my Amazon Alexa device states: "I am having problems connecting to the internet." When I check, I find that my main Wifi name (SSID) is missing (primary Wifi not discoverable on Wifi search) [I have 4 Wifi names: (1) for 2.4 (1) for 5.0 (1) for 2.4 extender and (1) for 5.0 extender). My recourse always is: reboot the router! I am still getting DOS Attacks (daily) but , so far, the noticeable disruption occurs only about once every few weeks! One noticable IP address that continually (Dos) attacks me is: Hurricane Electric LLC 184.105.139.105 Fremont, CA. So far, I'm just living with the occassionaly disruption!

Next time it happens do a packet capture with wire shark and email it to your isp. They may put it on their blacklist for you. Let me know what you find out and good luck.

I did discover that "Disable Port Scan and DoS Protection" was disabled on my modem. (How, I haven't a clue). So I unchecked that box. Still having DoS Attacks, though. As far as blocking IP addresses, I wish Netgear provided a "Blacklist" feature, or other means to do it. So far, I haven't discovered a means via my Netgear C7800. I have checked on that "wire shark" for a packet capture and will keep that in mind for the future. Thanks!
