C7000
I am a complete novice, so bear with me. We have Xfinity GB service and we are thinking of purchasing the CM1150V for the cable modem but we then want to use our already purchased C7000 as the router...

The C7000 will work as the cable modem and router but one I'd have to lowere service plan to 500mb which I'm ok doing, but then we lose voice. I'm looking into what penalities Id incur by cancelling the xfinity home and infinity voice and just haveing cable and internet at 500mb and maybe channel lineup. Then get Voip seperate.
That way the C7000 will be fine. My son in law said he hooked it up at their house and it doubled the wifi speed. But problem is they didnt have voice, we do. Speeds acheived are only fast if the device has capability so I dont have new enough items to get super fast that 500mb wouldnt be fast enough
but to your question, the C7000 cannot be used as stand alone router with a different cable modem on top of it. I wanted to use it as router function only but......

That explains things. Your first message didn't mention voice explicitly, although I should have guessed from the reference to the CM1150V.
I am not familiar with voice technology. I do know that 500 Mbps would be fast enough for voice and most other things.
I have no idea which Netgear boxes can do voice, beyond the CM1150V and the slightly older CM500V. (Those things often go under the "gateway" label with ither brands.) There are also modem/routers that do voice, the C7100V for example.
However, in general, experienced users like to have separate modems and routers. I was just thinking "money". After all the C7000 isn't that old.
Having two separate devices means that you have a bigger choice and more control over the kit. As you have found, you have not way of updating the firmware on the C7000. But if you put a router behind a cable modem, you get not only a bigger choice of features, you get something that you can update should new features turn up.

Not my question. I don't know a lot about cable modems. The technology is not widely used here in the UK. But I agree that it is hard to turn something into a router without a WAN port on the thing.

I think the C7100V maxes at 400mb and does voice and that would likely be better but thats another device bought. trying to increase wifi speed from xifinity modem and lag time for grandson games wihtout buying something. the C7000 they have doubled speed and lag went bye bye, but the voice is the hinge. Our cell phones sucks at home so we still hold the home phone for that reason.
I may just do the C7000 and add VOIP behind the scenes off the xfinity umbrella

Might looking into a cell phone microcell if you don't get good cell phone signal around your place. I have one. Works great since single at our place is bad.
