dos attack by ISP?

So the problem is fixed!! :) I am posting this so if anyone has the same problem they can fix it too. First things first the router and/or the equipment was not the problem. The problem was cox sent out dip**bleep** techs to my house over and over. When calling cox the last time I told them my modems power signals were not looking correct and told them about my modems logs. Ask your ISP for i believe what they call a "Data Tech" this tech actually knew what the **bleep** they were doing and fixed the issues. I had been dealing with this problem for over a year and it took the tech 30 minutes to fix my problem. So in ending this topic after the tons of hours looking on the internet and wasting my time JUST CALL YOUR ISP and have them fix the problem if your logs and symptoms are the same as mine, do not waste your time. Hopefullly this helps someone else out.

these were the errors my modem was giving to look my modems logs i typed 192.168.100.1 in the search bar:
