Pros: - 32 channels available for downloading. (my area only has 24 channels actual for downloading).
- Day and night comparisons in speed versus SB6121.
- Worth the price
- Arrived in 48 hours from placing order
Cons: - Blue LED lights extremely bright. May bother some people but so long as you turn the router to face away from you it won't be a problem.
Overall Review: Patience is a must even to activate via internet for Comcast.
Laptop & Ethernet cable required for activation.
Pros: Works as expected, connected to the Cox network with no issues encountered during provisioning. Currently subscribed to Cox HSI Ultimate Tier: 200Mbps up/22Mbps down ( OKC Market ), getting the current stated speeds from Cox with no issues encountered. Decided to upgrade to the SB6190 from the SB6183 based on the specifications, the SB6190 is a 32x8 modem and is ready to handle any network upgrades Cox performs on their network to yield faster speeds. Also the SB6190 is powered by the Intel Puma 6 Atom based SoC ( system on a chip ), right off I noticed that the SB6190 runs cooler than the SB6183 which was powered by a Broadcom SoC. The modems status and information pages are quicker to pull up using the modems 192.168.100.1 IP address. All in all the modem thus far seems to be a worthwhile upgrade.
Overall Review: I recommend this cable modem if you are looking to upgrade your current modem. Again thank you Newegg for expediting the order !! always a pleasure ordering from Newegg !!!
Pros: Fast. Was able to take advantage 24 (of the possible 32 the modem provides) downstream channels and 4 (of the 8) upstream channels with the top tier cable service from Cox. After replacing my last modem, providing the SB6190 with Cox technical, the speed test went up dramatically with no other changes. Here are the stats from the last time my laptop was directly connected to the modem:
Date Download Upload Latency

Paired with a fast router, it provides a massive upgrade when using lots of bandwidth. If you need the bandwidth and you are biding your time until gigabit fiber service gets to your place, this may be your ticket. Has mounting slots, though I would suggest adding some plastic spacers to keep the modem slightly separated from the wall or ceiling for heat dissipation. The modem has been running since December 2015 with zero problems.
Cons: The LED lights on the front panel should have a provision to dim or turn off. It is distracting during dark movie watching. Of course, if you put a piece of cardboard in front of it or tape a grey colored piece of plastic to the front, that solves the problem.
Overall Review: Recommended for anyone needing the throughput. Moving numerous graphics files now takes seconds, rather than minutes.
Pros: Can bond up to 32 downstream channels. Currently only possible with the Intel Puma 6 chipset that this modem uses, until first DOCSIS 3.1 modems are available with new Broadcom chipset.
Cons: Arris and Intel have publicly acknowledged latency/jitter/packet loss issues with the Puma 6 chipset used by this modem and many others. Do an internet search for "puma 6 latency" to read more. Until this is fixed I'm only using modems implementing Broadcom chipsets (like Netgear CM600 24x8 modem). I'm not expecting a quick fix (if ever) considering it took over a year between first reports of IPv6 issues on Arris SB6183 and cable company actually pushing firmware update to fix it.
Overall Review: Consider modems that use Broadcom chipset as an alternative, like Arris SB6183, Zoom 5370, Motorola MB7420, or Netgear CM500/CM600. All are 16x4 modems except CM600 is 24x8.
Pros: I have been enjoying my 2x gain in bandwidth with COX. They announced this service a few months back, and I wanted to take advantage of the free boost.
A 15 minute chat with the ISP tech support was all that was needed to switch in this new Surfboard. My tech was knowledgeable to correctly apply the correct configurations to use the additional channels for the service. I'm sure not all 32 are being used, when I checked my diagnostics, but that is not a problem, as the ISP currently only can take advantage of a certain number with their DOCSIS 3.0 implementation.
The good news for me was immediate gratification of speeds : 335 MBps / 33 MBps.
The web-based administrative user interface is straight forward and intuitive. It lists the essential properties of the cable modem's status with your ISP and other properties to help diagnose any issues.
Cons: If you are sensitive to blinking *bright* blue lights, affix some black electrical tape across its front panel.
Overall Review: Whether splurging on this versus the cheaper SB6183 will be known in a few years to see how far DOCSIS 3.0 can go. With DOCSIS 3.1 on the horizon, who knows what new benefits providers will roll out. The SB6191 claims to support up to 1.4MBps downstream with 32 channels. Give it 5 years, and lets see how the ISPs eventually catch up. For cable modem technology, this is so far, quite impressive.
Pros: Fast when it works
Cons: I ran GRC's benchmark tool and this modem fails miserably. Check it yourself and do some research. In any case, Arriss's admission and acknowledgment of the Puma 6 chipset issue took far too long. I cannot recommend buying this on that alone, regardless of performance.
Overall Review: This modem has a TWO YEAR WARRANTY. Newegg lists the warranty incorrectly as ONE YEAR. I just talked to Arriss a little while ago and they told me that. I will hold off on the replacement for now, because the speed issues I'm having are an upstream issue right now with my cable provider, they acknowledged there are 2 tickets open and opened a third today. In my case the modem was working fine for a year and may still be fine, I will know after they fix this upstream issue.
Pros: easily replaced my SB6141
increased my download speeds of 150mb to 180mb
no rental fees from Comcast
Cons: Docsis 3.1 on horizon. Had to call into Comcast to activate modem - what a PITA.
Overall Review: While this modem is "compatible" with U.S. cable companies. You *MUST* check with your provider to see if they have approved/certified it for their network first! Since this modem is soo new many providers have not at this point and will not allow it's use. 11/16/15
