Reddit reviews NETGEAR Cable Modem CM600 - Compatible with Cable Providers Including Xfinity by Comcast, Spectrum, Cox | for Cable Plans Up to 400 Mbps | DOCSIS 3.0 | 24x8

I have a Cisco DCP 3008. It works fine for now.

As long as you have a DOCSIS 3.0 modem with at least 8x4 I'd hobble along with what you got until DOCSIS 3.1. At least that's my plan.

Edit: I see your modem only has 4 DS channels. You can hobble along with that (though you might not get full speeds) or pick up the cheapest 8x4 DOCSIS modem you can find (something like this)

Alternatively, you can go balls to the wall with DOCSIS 3.0 if you really want to.

This! Sort of...

For one, you will need a cable modem:

• $45 NETGEAR CM400-1AZNAS Cable Modem 8x4 Bonded Channels
  
• $90 NETEAR CM600-100NAS Cable Model 24x8 Bonded Channels
  
• $100 NETEAR CM700 Cable Modem 32x8 Bonded Channels
  
  Why multiple options and price-points?
  
  In a nutshell, download and upload bonded channels supports how much up and down bandwidth your cable modem would have. 8 (8 download) x4 (4 upload) theoretically supports 340 Mbps download and whatever upload speed. My current 2x2 supports 125+ Mbps download.
  
  Why get something beefier? You will get slightly better performance if each bonded channel isn't operating near it's ceiling. With Comcast, they have 16 and 24 download channels in most markets so that will help with your overall connection. Also having 24 or 32 download channels will help you break through speed barriers if Comcast offers faster connection speeds in the future.
  
  Personal Note: I pay for 100/10 from Comcast and bought the $90 NETEAR CM600-100NAS Cable Model 24x8 Bonded Channels for my new home. While the theoretical download speed from the modem far out paces what I will get from Comcast, the new modem will take full advantage of the 24 bonded download channels in my area.
  
  Then you will need a router. With Ubiquiti, you can really go with one of two router options:
  
  
• ~$50 Ubiquiti EdgeRouter X
  
• ~$100 Ubiquiti Unifi Security Gateway 9USG
  
  There's a lot of YouTube videos that will explain the differences between each router. The short version is that they use the same hardware and have all of the same features available if enabled over command line but:
  
  
• The EdgeRouter X has more features available in it's existing UI, CAN be powered by POE and is less prone to crashing when making changes over CLI. The Edgerouter also has a built in switch (if you want) and POE passthrough so you can do: Cable Modem -> POE Power Injector -> EdgeRouter -> Ubiquiti Access Point (more on this shortly)
  
• The USG has fewer features in the UI than the Edgerotuer, CAN NOT be powered by POE and is more prone to crashing when making changes over CLI. What the USG does have is full integration into the Unifi family of products which means you can manage the router over the cloud along with any other Unifi product like your access points (APs... We'll get to them in a minute).
  
  Personal Note: I bought the EdgeRouter X because the price point is so good. This thing EASILY out performs my Linksys WRT 1900 AC or any other Linksys, Asus, etc. routers that I have ever owned. With that said, I will never fully leverage all of the controls in the UI and I wish I had gone with the USG as it integrates with the Unifi cloud stuff. I will eventually switch to a Unifi router.
  
  Then you will need an Access Point (AP) to create an access point for your devices:
  
  
• $75 Ubiquiti Unifi UAP-AC-Lite Lite
  
• $100 Ubiquiti Unifi UAP-AC-LR Long Range
  
• $130 Ubiquiti Unifi UPA-AC-Pro Pro
  
  If you get the EdgeRouter X, get a UAP-AC-Lite. They both operate off of 24v so you can do Cable Modem -> 24v POE power injector (comes with the UAP-AC-Lite) -> EdgeRouter X -> UAP-AC-Lite. This is what I have now.
  
  You can upgrade to the UAP-AC-LR which has the longest range of all of the Ubiquiti APs or the UAP-AC-LR because of it's 3x3 MIMO which gives it a higher input/output than the rest of the Ubiquiti 2x2 MIMO. The latter two devices use 48v POE injectors.
  
  Personal Note: I'm using two UAP-AC-Lites in my current two story home and will transition to four in my new three story home. Even at the cheapest price point, these far out perform the other routers and access points that I have ever owned.

Don't rent. Buy one. It'll easily pay for itself over a few months. There are different cables modems as well, the more common ones are 8x4 (8 downstream and 4 upstream). The newer ones are 16x4, which work with TWC's 200+ Mbps speeds. There are even crazier modems that just recently came out that can do 24x8, which supports nearly 1 Gbps.

Hi,
yes, Separate modem + Router is always better than Combo devices but it also depends on your needs and use-cases
read this link and see where you land: http://pickmymodem.com/cable-modem-wi-fi-modem-router-combo-one-buy/
for Suggestions om Combo devices: 1. C7000 AC1900 is pretty good http://amzn.to/2nbGF21 2. Motorola MG7550 is good as well and I have seen many good reviews http://amzn.to/2nB50PR
Both of these are Broadcom based and dont have latency issue which has plagued Puma6. Dont buy Low power WIFI Combos as you will regret later.
If you have high budget, I suggest you go separate modem + Separate Router
Modems: http://pickmymodem.com/approved-modems-for-xfinity-internet-service/
SB6183 (http://amzn.to/2minyUV) OR CM600 (http://amzn.to/2mG4zPi) are good choices
Routers: NETGEAR R7000 AC1900 (http://amzn.to/2qnhZG2) OR TPLink Archer C9 (http://amzn.to/2pRApP3)
Mesh??: Do you want Best WIFI range and have budget? then go for MESH WIFI systems: 1. NETGEAR Orbi RBK50 Kit http://amzn.to/2pq1ojA 2. Google MESH WIFI system http://amzn.to/2qmYqO7

Your signal levels look good. My guess would be like the others, which is that your node is overloaded during the evening. Ideally, you should try to get a technician to come out during the affected times of the day. Looking at your Channel IDs, it looks like you are in an area that supports 24 channel downstream bonding, so one thing you could try, which may help, but I can't guarantee that it will, would be to buy a modem like the Netgear CM600 which supports 24 channel bonding. This should give you more consistent speeds during times of high usage on the node, but I can't guarantee that it'll fully solve the issue. Best Buy also carries the CM600, so you could buy it, try it out, and if it doesn't help, return it. Also, make sure you DON'T buy a modem that uses the Puma 6 chipset (Netgear CM700 and Arris SB6190), as they are known to have issues with ping spikes, which still haven't been resolved with firmware updates. In the meantime, I'd suggest switching back to the Cisco modem they provided as it at least supports 16 downstream channel bonding, which is better than the 8 that your current Netgear modem supports. Just curious, are you in a Legacy Charter, Legacy Time Warner Cable, or Legacy Brighthouse area?

I use this one: https://www.amazon.com/NETGEAR-Download-960Mbps-Certified-CM600-100NAS/dp/B01621M1S4/ref=sr_1_1?s=electronics&ie=UTF8&qid=1481658576&sr=1-1&keywords=netgear+docsis

It works very well. (But Time Warner / Spectrum, not Comcast).

Regarding how you're not getting speeds: Modems support a number of channels and each channel operating at a certain speed. The modem you have can hit 170Mbps using its 4 channels. (43Mbps per channel).

Comcast probably isn't hitting that but has more channels available. Get more channels and you should see more performance.

Also, I've never had good luck with the Arris modems hitting the expected performance numbers.

Well, I know this is 5 months old but I found it while googling. Any thoughts on getting the CM600 over the CM500? Only difference I'm seeing is it is an upgrade from 16x4 to 24x8 (24 down, 8 up). Would that provide any current improvement and/or stability? Or does it just come down to a bit of future proofing? Hope you're still around to answer and thanks!

Hey, I was talking with a user in another thread and he mentioned something about a puma 6 chipset which some models use which apparently have problems. They may have partially fixed it with a firmware update but I don't think it's fully fixed. There may be lag issues with that model modem you are getting (SB6190).

If they haven't shipped it yet I would cancel the order. It MAY work okay but honestly I would just return it so you don't have any headache.

It seems like the better choices are the model below it, which I actually just bought used for $34, or the new model with DOCSIS 3.1 which is a bit expensive but is very future proof and about $160 after coupon right now on amazon.

I thought I'd alert you before you set up that modem! It's crazy they're still selling it like hotcakes. Maybe the issue isnt that bad but I personally wouldn't use it. It should be an easy return because its amazon.

edit: If you want a model in between the model below it and the very new model, this $99 Netgear is about the same price and is comparable to the one you bought (though a few less channels) and doesn't have any of the puma 6 problems.
