    Upgraded to Cox gigablast and this (Cox approved) DOCSIS 3.1 modem had great reviews. However, it will not connect. Just blinks green and never connects. Spent 8 hours on my day off with Cox and Arris tech support and...nothing. My other modem works fine through the same connection, but this one shows offline to Cox when it's connected. The minority of reviews are 1 star, unfortunately they are all true. Also this runs very hot like the other reviews mention. Going with a different brand.

    DOCSIS 3.1 is worth the upgrade

    Works as expected. This was an upgrade to DOCSIS 3.1 over my previous Arris with DOCSIS 3.0. The upgrade was necessary to access full bandwidth on my internet service package.

    Setup was easy and this modem is more stable then what I received from Comcast. I also can now control my settings when hooked to a router without having it all in one.

    The S33 works but if you are on Xfinity and have the 2000Mb service with increased upload it doesn't work as well. Xfinity for some reason isn't allowing the S33 to upload any faster than 40Mb. The S33 can upload up to 2500Mb but for some reason Xfinity is preventing it.

    And shes toast. Outside Best Buys return policy so i am trying to get the 15% off a new one. Oh and the self activation is fake. Never had one I was able to "self activate" and the fact that they advertise this should be reviewed by the FCC
