    No complaints as it does as it advertises. Had to upgrade and this was my only choice basically due to Comcast.

    Reliable Upgrade For Comcast Users w/ Room To Grow

    I use Comcast for cable Internet, where over time it is required to upgrade the modem to keep up with infrastructure upgrades. In short Comcast recently updated their infrastructure to offer higher speed connections. The result was not only that my older modem could not take advantage of the higher speed offering, but in fact was under performing because less channel capacity was allocate to legacy modems. Setup was something of a hassle where the instructions say you can setup the model without a cellphone. In fact I was forced to download the Comcast app to provision the new modem. Once provisioned, I deleted the app from my phone. All that said one the modem was provisioned, software updated, etc it is 100% solid without any dropped connections.
