I have had the same problem for about two weeks now. I was having problems with my modem so comcast told me to go get a new one. I get it hooked up and within a day my internet keeps dropping. My modem will actually reset and then come back online. It happens to me more at night then during the day but it happens and at least 10-15 times. Comcast keeps telling me that its my router but I just went out and bought a new router about 6 months ago. So I have a tech guy come out and he tells me that its prolly not my router and that if it is my modem he will swap it out for me. He goes and tells me my port to my apt is bad. It fails then passes then fails then passes. So he moves my port over to another one and tells me that should have fixed everything. Swaps the modem and then leaves. Everything works perfect for about 6 hours then blam....internet fails. That was yesterday. As of today I have lost internet 5 times and its not even 5 o'clock. The problem I have is I have never had any issue with comcast until I had to get this new modem. Even the tech guy said that its a new modem from the company and that its a Cisco product so you know its good. He tells me that its possible that comcast just didn't configure everything right when they set them up. I don't care what has to happen but I would love to not loose connection every 20 min. Comcast tech support is a joke. Every time I call they can't help me with anything but are always fast to tell me its not them its me and my router.
