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)
ARRIS SB6190 DOCSIS 3.0 Cable Modem - Retail Packaging - White
  • This modem will suffice for years to come. With a maximum connection speed of 1.4 gigabits per second, this modem is Future Ready. As at the beginning of 2017, the average DOCSIS cable speed is 75 megabits per second.
  • This is very good. My ISP gives 300 mbps and i am getting the full speed.
  • The ARRIS - SURFboard DOCSIS 3.0 Cable Modem enables up to 1.4GBps data transfer rates off cable internet services that support high speeds. I installed it in Truckee CA and the cable speed went from 192MBps to 498MBps. It handles up to 32 simultaneous channels down and 8 up.
  • Delivers blazing fast speed to my house. I have it paired with a netgear nighthawk x6 ac3200 and couldn't be happier.
  • I have Comcast and this modem maintains my speed at or above my plan with Comcast. So far the best modem I've had.
  • It works great. But sometimes it loses its signal. I don't know if it's the modem or Comcast. My bet is open Comcast. Wish it had telephone capabilities.

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
ARRIS SB6190 DOCSIS 3.0 Cable Modem - Retail Packaging - White
  • This modem set up very easily by connecting a PC directly to the port. After set up I attached a wireless router
  • Good speed. Setup is fairly self explanatory. Only one port so definitely need a router or Ethernet switch.
  • Great price for a simple router. Wish it had more ports but I connected the device to another device so I could hard-wire several rooms.
  • Needed a phone port on our cable modem.This one didn't have a phone port so needed to return it.
  • Modem worked well for the first 50 days and then today the ethernet port just stopped working - verified through Comcast that the modem was receiving a signal but no signal coming out from the ethernet port.
  • I returned this Docsis modem 3.0 for the 3.1 modem. The 3.0 model does not have enough ports for my needs. The 3.1 Surboard is great and has the extra ports needed for extra connection.

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
ARRIS SB6190 DOCSIS 3.0 Cable Modem - Retail Packaging - White
  • Our speed doubled after changing to this 32 channel modem. If you have 50 MBPS speed or greater, you need better than an 8 channel modem.
  • Most cable companies require a 16channel downstream bonding modem and this one has 32 to allow for some future overhead. Very satisfied.
  • The channel combining on this modem is impressive.
  • Love the extra channels. I've seen a good boost in my bandwidth after upgrading my 8 channel modem
  • The modem is good. Never had any problems. The only problem I have with modems like this is there is no power button for on and off.
  • So far it has been fine. I would like it to have a power button and better directions.
