Motorola MB8600 DOCSIS 3.1 cable modem. Used condition with original packaging. Eliminates monthly rental fees. For use with cable providers like Xfinity Comcast. Used for 2-3 years but am selling only because we’ve upgraded to a whole home mesh network system. It’s always worked great, reliably, and produces fast speeds. We’ve used it with services at 400 Mbps. It’s never been dropped or mishandled! Just pricing to sell fast.
