Sigh.
This is why I didn't want to call. I knew I would be dealing with nothing but incompetence and ineptitude.
At about 5:45pm today, I finally gave in and called after exhausting every other option.
This first call was disconnected before I had even finished giving the tech the CMAC id.
The second call, the tech insisted there was a problem with my inside wiring (despite the old modem working perfectly and the new modem displaying very good signal levels). Most of the call was a sales pitch for Comcast's "Service Protection Plan" would wound ensure that when the tech comes out to repair my apparently faulty inside wiring, I wouldn't be charged for this wonderful service. Funny thing is I don't really have any inside wiring. I live in a condo with three other units. The drop from the pole is attached to the exterior wall of my unit, and from the tap goes about 6" to a hole in my wall where the cable modem is plugged directly in with no splitters or additional wiring.
So next call, the tech says they need my serial number in addition to my CMAC id and I'll be up and running in no time. After supplying this information, and predictably still no connection, I'm told the issue will need to be escalated and am provided a ticket number with assurance that I will receive a call back in 15-20 minutes.
Fast forward an hour, still no call back. I call and reference the ticket number, and am advised they will need at least 24 more hours to resolve the issue.
So now here I am with no internet service, and three cable modems that don't work. Thanks Comcast.
In the mean time I've been able to learn some of the workings of cable modem CPE and plant technology. Using the event logs and status pages available on my modem, I believe I've isolated the problem to something in Comcast's equipment. The head end seems to not want to issue my modem a DHCP address. Sync is good with solid upstream and downstream power levels and SNR. Hopefully someone at Comcast will figure this out soon. I've wasted enough of my day on this bullshit.
