comodo and my ISP

I use comcast broadband internet, and recently I’ve been having a lot of problems and I was wondering if it could have anything to do with comodo. I know that any isp has to be able to send and receive packets to and from my computer. So is there anyway that I could have blocked my isp which in turn disabled my internet? how do I know which IP is their’s in the connections list? or is my problem totally unrelated? please help me out.

Hey kirvixus I have a friend who is using the Comodo firewall and he has Comcast Cable internet and he has not had any problems with his ISP and comodo. Hope this helps have a good day.
