I have been with comcast for no more than one week and i have spent two of those days troubleshooting why our gateway keeps losing connection.
First time we lost connectivity I noticed that the WAN DHCP subnet mask and default gateway to be 0.0.0.0. Thinking this was the issue, I power cycled the modem to try to regain these settings back. The result was that I was no longer able to access the gateway anymore or even ping it while being directly connected to it. After resetting the gateway to factory and regaining an internet connection and reconfiguring it again for our office network, it lost connectivity again after a couple of hours. The solution was to reset it again and reconfigure it again to match our existing network. I am pretty fed up with it and i believe the culprit to be that the subnet mask and defautl gateway are still at 0.0.0.0.
I fully expect to lose connectivity again. Phone support has been useless aside from telling me to rest the router to factory again.
here is a picture of what my gateway reports.
