I was looking for the fastest cable modem for my Xfinity Internet and this was the fastest cable modem that I could find. This cable modem does not have built-in Wifi and that’s what I wanted because I connect it to my mesh network equipment for WiFi. The Motorola MB8611 DOCSIS 3.1 Cable Modem has been super reliable and fast! To make things better, I don’t have to pay Xfinity a monthly lease fee for a cable modem, since I own this cable modem. It’s great! #Motorola #MB8611 #Xfinity
