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.

    You know the deal, I should be getting much faster internet speed, but either Comcrashed, my modem, or my router is not doing it’s job. My guess is that it’s not the modems fault!
