What customers say about "Key Specs"
ARRIS SB6183 Docsis 3.0 Cable Modem- Retail Packaging- White
- This is one of the few units that TWC supports on 300mbps. Don't be fooled by the other versions saying they will do up to 300mbps, they don't have enough downstream channels and aren't supported at those speeds.
- Definitely faster. I was getting between 30-50mbps downstream and 2-5mbps upstream with the SB6120. With the SB6183, I'm pulling 80mbps downstream and 4-5mbps upstream. Huge improvement.
- I get 300-350 down line of sight or in the next room over on my MacBook Air on the 5ghz AC band of my router.
- Does what it says. Supports TWC and we have 200mbps, and this seems to support all 200+ (it's rated for 300)
- Does get hot though, so plan on leaving it on a desk and not touching you (or anything heat sensitive for that matter)
NETGEAR CM500 DOCSIS 3.0 Cable Modem (Compatible with Spectrum, Xfinity, Cox)
- We had to replace our modem and router because of the speed and range. We are extremely happy with the speed of this modem. We have a two story house and our wireless now works throughout the entire house, including garage.
- I have TWC and am getting 220mbps d/l speeds and 25 upload speeds, which are both more than what I am paying for so this thing rocks! Easy to setup and works great!
- Great speeds for downloading data. Switched to streaming TV and it supports the streaming with no buffering.
- Before adding this modem to my Comcast network, my internet speeds where not up to what I was paying for. Now they are almost double what I'm paying for. I love it!
- We needed a new high speed modem and the Best Buy sales person recommended this one. We have been very pleased with it.
- After buying this product we got it home only to find it was slow and wasn't wifi...
- I bought it but unfortunately I didn't keep it because it slowed down my internet with xfinity.

What customers say about "Ports"
ARRIS SB6183 Docsis 3.0 Cable Modem- Retail Packaging- White
- Easy to hook up to my router. Would have preferred that it had a telephone port in addition to an Ethernet port.
- Bought this modem to replace one that was fried due to a power surge. Love the fact that it has a gigabit port.
- The only downside is not dual ether ports, but otherwise, it’s top of the line modem.
- The only downside was it needs more output ports.
- Works well but could use one with more ports to hardwire more applications
NETGEAR CM500 DOCSIS 3.0 Cable Modem (Compatible with Spectrum, Xfinity, Cox)
- It only has one port so if you have multiple Ethernet ports throughout your house and you want to hard wire each computer, this isn't the one for you. But if all your computers are on wifi, it works great.
- I had my own router so just needed something to make the link with my comcast cable. Despite it has very simple feature set (only one RJ45 port), it works fine and was easy to setup following the quick start guide steps that explains the comcast activation too.
- This was recommended by a "blue shirt" as a solution to replace my cable modem but it it didn't have enough Ethernet ports to do the job. I'd recommend based on ones needs for ports
- Unfortunately, having only one ether port did not work for my more advanced needs. However, looks like a great modem for simple usage.
- A Best Buy Rep AND a Spectrum rep suggested I purchase this to replace the modem that Spectrum supplies for free. I've not had problems with speed, etc. but beware that this only has one ethernet port (as opposed to Spectrums 4) so you need to buy an Ethernet switch.

What customers say about "Features"
ARRIS SB6183 Docsis 3.0 Cable Modem- Retail Packaging- White
- This is one great cable modem. Having the 16 downstream bonded channels has really sped up my connection with my ISP. Thoroughly happy with this purchase.
- Modem is capable of 16 downstream channels, so I purchased it in anticipation of service being upgraded in future from currently available 8 channels for download.
- On average we have at least 18 devices connected, and sometimes 25!
- Short and sits upright, or upside down. It's a nice little flat rectangle so it's easier to mount/place anywhere. Even on the front.
- It's bright white with very bright front LED display indicators.
- Takes a while to boot up. Like on the order of 15-20 seconds.
- Gets a bit hot during normal use. Needs better thermal design, in a consumer device this shouldn't be an issue
NETGEAR CM500 DOCSIS 3.0 Cable Modem (Compatible with Spectrum, Xfinity, Cox)
- This is a high end modem. It has 16 channels, and a lot of security options and quality of service options.
- I bought this in replacement of the cheaper one I bought, because my internet has to have 16* 8 channel to work fine without disconnecting.
- Netter's new modem offers all of the basic features that most consumer's may desire for a reasonable price.
- This Cable modem was so easy to install that in 15 minutes I was set. All the other features were great and exceeded my expectations.
- A lot of great settings from simple to advanced features. Highly recommend product!
- This is a high end modem. It has 16 channels, and a lot of security options and quality of service options.
