Customers are saying

Customers are positive about the product's impressive speed, strong performance, and overall ease of use, including its simple setup and seamless connection. They also appreciate its compatibility, DOCSIS 3.1 support, and affordable price, noting that it operates without lag and stays cool. However, customers are negative about the limited number of ethernet ports and, for some, the signal strength.

    Per comcast new requirement, you need a Doscis 3.1 modem to have their 1 gigabit service (even if the modem says can support gigabit speeds, like the SB 6190, if its not Doscics 3.1, IT WILL NOT WORK WITH COMCAST). So I had to get this one. It worked fine, however I wasn't getting the speeds, I was maxing out at 400mbps, contacted comcast they reprovisioned and nothing, same. I don't know if it was defective or some incompatibility there. I had to exchange it for an Arris SB8200 and that one worked fine. YMMV.

    This device is a great addition to our home wifi. After who knows how many years of paying a minthly equipment fee we decided to buy our own equipment. At the end of the day do yourself a favor and buy your own equipment.
