Hi, Like my last post about Wireless router help I am thinking of also upgrading my Current modem.

I found these two but not sure if these are good choices or which I need . I have 400 Speed internet at the moment.

I do need a spot for my phone to plug into. and would like a couple ethernet ports. Can I not do that with the CM600? I read something about a switch but I have no idea what I would need.

Thanks
 
The Netgear CM700 modem also has the Puma 6 chip and would definitely avoid that one. And modem/router combo units are no good as well.

I also have a 400/20 HSI plan and I highly recommend the Netgear CM600 modem along with either a Synology RT2600AC router/Netgear R7800 router/Asus RT86U router.

I have the Synology after being a longtime Asus user and I'm very pleased with it's performance, speed, firmware and customer support.
 
If you need a cable modem with telephony, that considerably narrows down your choices. I was happily using Arris modems, the TM722g and then the TM822g, until I got higher speed internet. Once I got up to 300Mbps, the TM822g no longer could give me the full speed that I was paying for. So I now have a Netgear CM500V ("V" is for "voice"/telephony), which is working very well.

Of the two that you mentioned, I wouldn't go with either of them, neither has the "voice" or telephony part that you need. First off, I don't see what ISP you're using? That will affect what modem you can use. Comcast, the ISP I use, has a list of modems that are confirmed to work with their service. Secondly, look for the telephony/voice piece in the specs of whatever you buy...if the modem supports VoIP, that will be listed in its specs. For Netgear, the product name will end with a "V" if it supports telephone use.

As far as multiple ports/switches go, usually people will use a router plugged into the modem, and that will give them multiple LAN ports. You mention that you already have a router (or you posted for help with choosing a router, can't tell), so that's where you will have LAN ports that you can use to plug in your devices. A modem will only have one ethernet port, unless it has a built-in router. I tend to avoid the "combo" modem/router devices (also called "gateways" by your ISP), because they're less flexible when it's time to replace your modem or router...you obviously have to replace both if you have a combo device. I don't know if your router also supplies wireless for mobile devices, but that's important to most people these days with smart phones, tablets, etc.

I wish you good luck putting together your home network. The important takeaways here should be to start with your ISP in finding a modem that'll work for you. And keep in mind that you need the telephony piece in that modem as well. A separate router (which you may already have) is recommended for connecting to your modem so that you can connect multiple client devices to your network.

Usually when you're paying for phone service through an ISP they provide your modem. If you want to use your own modem for internet access you can sometimes run separate modems; the ISP's modem for phone and your own modem for internet only. In previous years I have helped multiple people using TWC add their own modem for internet access while continuing to use the TWC-provided modem for phone service. I assume that you can still do this with Spectrum.

So this is the CM600 but I don't believe it does phone, What is a good one that does phone?
I have spectrum/TWC.
They supply a router the arris 1602 I believe which I hear is laggy and has the puma chip.

I mentioned the Netgear CM500V, a 16-channel modem with VoIP. I've found that you can realistically get 30Mbps per channel, so the 16-channels on the CM500V would give you at least 480Mbps. So it should do 400Mbps just fine. I see that the CM500 is on their list for up to 300Mbps, it can do more with 16 channels, I guarantee it *smile*.

However, the fact that the Spectrum/TWC online list of approved modems doesn't list any modems that include voice is telling...you should get in touch with them and ask them about that before buying a modem with voice. They may require you to rent a modem to use their VoIP. I would hope not, but you never know. Or, maybe as the other poster suggested, they will allow you to use a separate telephony modem? If you could buy that, anyways. Otherwise, you may be stuck renting at least a separate telephony modem, I'm sure that they'd like that.

Honestly I am not sure if I am paying a rental fee, for some reason I belive they waved it for me but I will have to check.
 
You know, this has brought up an interesting possibility for me. I still have the Arris TM822g, which this has gotten me thinking about configuring it for voice-only, then I could get whatever internet modem I want without it needing a telephony portion. Like I could get a DOCSIS 3.1 modem, and have the latest. I doubt that I would ever have to think about a voice modem again if I did that, the Arris modems have been so reliable.

I'll give that some thought...good thread, giving me ideas *smile*.

Sometimes it's part of the deal that they give you a "free" modem...that is, they make giving you a modem part of the deal to sweeten it a little, so no rent to pay. AT&T sometimes does that...when I signed up for their 1Gb. fiber, a modem was included that I would own at "no extra cost", and no rent for that modem.
 
The whole DOCSIS version throws me off. The only thing i dont like about adding anthoer modem is more wiring. I guess I could always move the phone somewhere else.

If you're with Spectrum, they still don't list any DOCSIS 3.1 modems on their Authorized Devices list.
 
Spectrum will give you an all-in-one modern (with phone). Have Spectrum bridge that modem for phone only and use your new modem with your router for internet. I have this setup with Spectrum and it works great.

Nope, mentioned above that I'm with Comcast. I see that the Netgear CM1000 and Motorola MB8600 are on Comcast's list and they are both DOCSIS 3.1. Don't know if they've implemented 3.1 features yet around here yet...we're in a backwater as far as Comcast's infrastructure goes. There may be other DOCSIS 3.1 modems on Comcast's list, I didn't look any further than the CM1000 and MB8600.
 
What about the Arris SB8200? That works with Comcast and most people reviewing it say it’s the best DOCSIS 3.1 modem.

I am leaning towards the Netgear, But I am wondering if I should get the CM 1000 over the 600. My ISP ( Spectrum ) said that even though it is not on list they could probably activate it. I Currently have 400 Mbps service but I can get 1 Gig and may at some point.

What do you guys think of these ? I am thinking CM 1000 as that should future proof me. Am I missing something?

Couple of things.

Spectrum is just using their approved modem now for Gig service. They haven’t approved any others as of yet.

The Netgear CM600 is good for 400 Mbps and it doesn’t have the Puma chipset, which has latency issues. I believe the CM1000 has that chipset.

No. The DOCSIS 3.1 modems Motorola MB8600, Netgear CM1000, and Arris SB8200 all use Broadcom chipsets, which are the best in the market.

The Netgear CM1000 is a good modem and probably the easiest to use of all three. If OP wants to attempt to use it with Spectrum after they indicated they are in practice open to provision a non-approved modem, then that's great for them. Worst case scenario if they buy it from Amazon, they can just promptly return it and get a CM600.
