DOCSIS 3.1 Modem
Hello all. First post here. I’ve had a CM1000 modem for at least a year if not longer. Recently I was chatting with an Xfinity support rep and he said for the new IP 4K box I would need a DOCSIS 3.1 modem. He also said that what I had, which is a CM1000, wasn’t enough. After researching, I settled on the CM1000 and then realized I had one. Now I’m wondering if they updated it and is the one I have any different? Can mine be upgraded with firmware because the ones in the store say DOCSIS 3.1 ready. I’m confused and wonder if what I have is enough.

If there was a update for upgrading 3.0 to 3.1, then it comes from NG then they pass it to ISPs before ISPs push it to customers modems. Something to ask the ISP about. Be aware that some ISPs don't push FW to customer owned modems.
- Thanks for the comment FURRYe38. Is it possible that the one I have is indeed different than what’s on the shelves in terms of performance? I’ll get another one if that’s what I need, just thought the box would be noticeably different
Some ISPs required actual DOCSIS 3.1 modems for there 1Gb services. The ISP will have to ensure the CM1000 is compatible, if not, then find a actual DOCSIS 3.1, CM1100 or 1200 if you decide to go with NG.
