Upgrade from another SURFboard
I decided that after a long time, an upgrade from my SB6120 was due. Was looking to increase my speed, or at least have gigibit ethernet on my router so that I could take advantage of higher speeds. Installation for me was painless. I have Comcast, it is a supported router for them, called up, provided MAC, and less than 15 minutes up and running. Read a couple of reviews after I got it and, while my paid for internet speed is only 100 megabits, a far cry from what the actual modem can do, I see no tangible difference, but I wasn't expecting a giant speed boost, just a little. For me it is stable, but I do notice that the jitter is a little higher. If you look at my screen shot, the left of the large spike is the old modem, the right, new modem

    Quick and Easy!
    I bought this modem to replace my existing Spectrum-issued Arris modem/router combo. I paired this modem with three Google Wifi pucks and all my problems with internet service disappeared. Modem is small, looks nice and is a snap to set up. Like others have said before, I'd really like to be able to dim the LEDs on the front, but its not a huge problem for me.

      Good concept, flawed execution
      I bought this modem six years ago and it was very solid/stable. It did what it needed to. About a month or so ago I started getting random dropouts then it completely stopped working. Six years is a good run and I was planning to upgrade to a DOCSIS 3.1 modem anyways, so I opened it up and found out what the failure was. The modem generates a lot of heat (which discolors the plastic case, fyi) and the heat sink on the processor is held on by plastic clips. Over time the heat, apparently weakened the plastic to the point they snapped and the heat sink fell off (it's mounted sideways). My guess is that the lack of the heat sink is why the modem started dropping out and then eventually fried. This is just poor manufacturing on an otherwise good product. If they ahd used metal screws, instead of plastic clips... I'd still be using mine today.
        Great upgrade!
        We bought this product because we upgraded our internet service and our older Arris modem needed to be upgraded. The ordering was easy. The item arrived promptly. It was easy to set up and get running. It seems to be doing it’s job!

        Rock Solid Performance
        Installed this modem at our international denominational headquarters (11: work-stations, 2: emergency phone lines, 3: big-screen TV's and video security). We have had it installed for 2 years (powered through our UPS) and we have had to reboot the thing a grand total of 4 times. This beast is a rock-solid workhorse.

          Easy, really easy
          This is my 2nd SURFboard cable modem. The old one worked just fine except that in upgrading my internet speed, it was too much for the 8 year old modem. Since I was happy with the old modem, I didn't look at any other brands when purchasing a faster modem. Easy to set up and with a quick call to my internet provider, and it was up and running within a few short minutes. I am very happy with this cable modem!

              Does not work with Xfinity
              I just bought this modem and Xfinity could not add it to my account, they told me that something was wrong with it from the manufacturer and to return it and get a different modem. After reading reviews, seems to have a common issue related to a bad chip and a lawsuit concerning this. Wasted a lot of time trying to get it to work, very disappointed. The surfboard modems used to be the best.
                Replaced my SB6141
                This modem has been working flawlessly with Xfinity 300 speed service. You can log on to the modem and turn off the status lights if you want they are really bright.
