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.

    I needed a new modem so I tried reading reviews on what would work well. This one does. Four stars because it’s pretty expensive, but maybe it won’t become obsolete in a couple of years.
