A:Answer It will work fine with Comcast. However, keep in mind that this may be an issue with your Comcast connection to the modem versus a router issue.
If you Ethernet-connect a computer directly to the modem, you can see if the problem is originating BEFORE the router.
Your modem lights should NOT cycle all the time to "provide you with better service". This sounds to me that your Comcast connection may need work. I have had Comcast for years now, and while yes, they will occasionally upgrade service which would re-set your modem, it absolutely should not be a regular/frequent thing.
