*** THIS IS LIKELY THE SOLUTION***

I just had the same problem of disconnect connects and bought a new router cable modem and still had the issue. Comcast came out twice. The first guy removed some splitters and the old amplifier I was using from them and while speed increased the disconnects or drops still occurred. I researched and found the main issue for me and it not what a lot of Internet  articles tell you about old routers etc it is actually the fact the Modem receives your data but also has to send back acknowledgment to the system called an "up load". If you have too many splitters or bad connectors or even dirty tarnished coax tips the upload signal is too weak from your modem and if the signal does not get back consistently, your modem will disconnect and reconnect. Once splitters were reduced and cable unions replaced with new ones or at least unscrewed and retightened with a wrench and most importantly a direct line from the street to your cable modem (going thru only the initial splitter), the problem will usually be resolved. You can test this yourself by replacing any wire behind the wall with a direct cable connection to your cable modem. The tv does not have this issue as it is the internet connection that needs to do the uploads. If you do that direct connection (and clean and better replace any cable unions that join pieces of coax) you should be good. Trying to get this message out as it was so frustrating to have these drops in the middle of watching a movie ! If this does not fix your issue, then its time to look outside your house for issues with the Cable signals or amplifiers on the street but Comcast can tell its in your house if you are the only one on the street with this issues, If many in the area have this issue its their problem likely to fix. Thanks to Comcast Tech Carlos in Lowell Mass who solved this issue for me ! Mark
