This is my last resort, I've been calling Comcast non-stop for the last 10 days, and I still have no solution:
I bought a new Cisco DPC3939 cable modem because I wanted a Cisco, and it was the only supported one with integrated Wifi. "Supported", because it is listed in Comcast's DOCSIS information center:

I took a screenshot, just in case they decide to remove it: http://imgur.com/ImQFcLO
Now, for the last days I've trying to register and activate the modem, without result. I've been told a several different things, like
- That the modem is not supported: FALSE. Proof above
- That I can't have this modem, it's only for Triple Play, and I just got Double Play (internet & TV). FALSE: it's a cable modem, should be perfectly valid for internet, otherwise it should be clearly stated in the supported list
- That they cannot provision this modem, because they don't have the activation code. This is the greatest mislead: Comcast is listing a modem as supported, when it's clearly not, when they cannot even provision it!
I went to the Comcast store yesterday, hoping they will be able to help me. They told me the same story: they couldn't register it, and that I had to call the same number I've been calling for days.
Last call yesterday, I was told the "cannot provision it" story again, that I had to buy a new modem, and that the best they could do is offer me $20 credit... for a modem that is worth more than $100.
I've been misled by Comcast, to think DPC3939 was a supported modem, when it's clearly not. I don't know if they'll support it soon, but I don't care, I'm paying for a service that I'm not receiving, because I don't have a working modem.
Tip: if you're thinking about buying your own modem, make sure you call Comcast first to verify they will have no problems registering and activating it.
