If others are having the same problem and not just in your home then it sounds like comcast may be experiencing some line noise or signal loss.
When your system loses connection do the other systems stay connected?

Anyways when your internet drops how long is it out for? And does the internet light on your modem go out? If not and the modem looks like it does when it is connected then it is an internal issue with Comcast. It can be a box on the street, a sub-station, or their primary station for internet services.
Next time it goes out try and go to this web url (bookmark it now so you have it). Try this site http://188.8.131.52/ it is for opendns status page. If it loads when your internet is not working then it is because of the DNS servers that Comcast operates are faulty. If it doesn't load and your modem is still synced (ie connected with them) then there is damage/short in the line from your location to theirs.
When I first started experiencing this issue I tried opendns, but it was painfully slow for me. I ended creating a DNS server that pulls from multiple DNS servers. And I haven't had the issue, I've also setup redundancy were if the Domain I am searching for isn't on my local servers it tries Other dns servers for the information with an ultimate fall back to comcast dns servers. It worked for me for about 2months then the issue came back. And Comcast just don't care. If another Highspeed Internet Provider is in your area I suggest you to switch, I know I will soon as Fiber Optic comes in from one of the local ISP that is putting it in.
