Has anyone else been getting DDoS attacked?

This has been going on since May or June and I have hundreds of logs saved with thousands of these same entries. Xfinity/Comcast won't do a thing and of course says "everything is fine on our end" and "your connection is stable"...etc. They won't address this actual issue whatsoever. 

So, multiple times a day, I'll be browsing and all is fine then all of a sudden I cannot connect to anything for five minutes or so at a time. I'm using my own Netgear modem/router combo, but this was happening even when I was leasing a modem from Xfinity. I generally just login to the router, kill my DHCP lease, wait 10-15 seconds and reconnect. Everything will be fine for another 1/2 hour or so and then it happens again.  

I've used other routers and put mine in bridge mode, but it just starts happening again, even with a different IP address. 99% of the time, it's coming in through DNS port 443, but there will also be other random ones here and there. No matter what I do, it just keeps happening, even blocking the port through my firewall it doesn't really matter as it's killing the connection at the modem level. Anyone else seen this or have any ideas on what to do? Thank you in advance!
