What customers say about "Key Specs"
ARRIS SB8200 SURFboard DOCSIS 3.1 Cable Modem
  • Ok it has taken 3 days of Comcast phone calls to get this to work. However it now works. Had to pay more to run the 3.1. But it is what it is. This is very fast. I have 352MB download and 45MB upload.
  • I LOOOVE THIS little Beast! Moved to a house and my friend had the slowest package from COX. I decided to upgrade to Ultimate package, bought this guy, and now my Internet speed is 350-380 down, 32 up (I know COX says up to 300, so seeing more than 350 down makes me even happier).
  • Was able to activate with WOW! easily though a quick phone call to their customer service line. Consistently exceeds the 500 Mbps down and 50 Mbps I am paying for.
  • Great modem for 1gigabit service comcast. for self install call rep to get the modem provision and bootfile for correct speed.
  • From Cons, I think it becomes quite Hot, but I keep it separately on the shelf where air flow is quite good, so I hope this heating isn't an issue at all.
NETGEAR CM1000 DOCSIS 3.1 Gigabit Cable Modem
  • The modem works so far. Our internet speeds are where they are supposed to be. Stop renting your modem and buy it!
  • I subscribe to the 150mps download speed and the results at speedtest.net were clocking me at over 165mps. I've run the test several times since then and the results remain the same. I haven't had any connectivity issues since its registration.
  • Comcast Blast speed with the 6183 was around 165 mbps and after I switched to the CM1000 it jumped to over 220 mbps wireless!
  • We are getting nearly identical speeds at the main router and at the satellite (over 230mbps down over wifi to an iPhone X). I am VERY VERY impressed with how easy it was to setup and how well it works.
  • I’m very disspointed with the speed. I pay for 200Mbps down and 10mbps up. My old docsis 3.0 surfband modem was able to pull 220Mbps down and 12 up. This modem wants to pull 170Mbps down and 4Mbps up.
  • For a DOCSIS 3.1 modem claiming to hit up to 6Mbps - this modem was not able to get close to even gigabit speeds. I had a veteran Comcast technical at my house for hours, trying to get this thing to work correctly.

What customers say about "Ports"
ARRIS SB8200 SURFboard DOCSIS 3.1 Cable Modem
  • It has 2 Gigabit ports for 2 separate networks (Global IP's) and can utilize link aggregation.
  • The dual LAN ports on the back are cool, but only useful if your provider allows you to use the second one--sadly, Comcast Xfinity does not.
  • I chose this one for the two ports in the back.
  • Very easy to setup and get working. This was purchased because we needed two ports, both of them are gigabit and DOCSIS 3.1 means that we are set for future speed increases.
  • Great cable modem...fast... as described, there are 2 LAN ports on the back..
NETGEAR CM1000 DOCSIS 3.1 Gigabit Cable Modem
  • Ethernet port is bright yellow. Sounds silly, but when you're reaching into your darkened equipment rack, a bright yellow port really helps.
  • It’s ok. What they don’t tell you is it will NOT work with your current cable tv account. Because it doesn’t have a telephone port in back.
  • Bought this about a month ago, and it seems like the Ethernet port has failed. I've swapped out with another router and I can receive internet just fine, but when I plug it back in, the router and my laptop wont receive internet.
  • Buy this as the cable rental replacement, but the ethernet port lost connection all the time.
  • I wish the unit had two gigabit LAN ports so I can run one to my router and the other to my OOMA phone box or switch for OOMA and Google Phone.

What customers say about "Features"
ARRIS SB8200 SURFboard DOCSIS 3.1 Cable Modem
  • Works easily on Comcast, dual Ethernet, removed my Bufferbloat issues
  • I have had a little over an hour of downtime since I put it in, and that was a scheduled network maintenance outage Downstream is connected 24ch plus an extra 3.1 channel via docsis3.1, upstream 4ch is still 3.0
  • Upgraded old modem using DOCSIS 3.0, with 4 channels to SB8200. Speed doubled at least. No problems found.
  • Expensive, new so may still have outstanding CMTS connection issues (but not for me)
  • Even though it is DOCSYS 3.1 and the description says it works with Xfinity Gigabit, it doesn't. Only 250MB and below.
NETGEAR CM1000 DOCSIS 3.1 Gigabit Cable Modem
  • We have Comcast, this modem is supported by Comcast and it’s super easy to set up. It took less than ten minutes. If you have Comcast there are specific instructions to set it up. Very easy.
  • I'm also using the NETGEAR Nighthawk X6 AC3200 Tri-Band Gigabit WiFi Router (R8000) with the CM1000. They pair great together and I've yet had to reboot this modem.
  • Fool proof airflow design. No matter which way it is oriented, surrounding air will provide cooling
  • I expect the 32x8 channel bonding to be future proof for my needs.
  • Only comes with a cat 5 cable (yes, no a cat5e or cat6 cables, a cat5 cable!!!)
  • As a D3.1 modem, it only supports 1.0 Ghz downstream, and 85 Mhz upstream.
  • Should be mounted vertically for proper heat dissipation. Not an issue for me, but could make fitting in your equipment rack difficult (height= 6.75in or 17cm).
