My cable modem is a little over 3 years old. I am currently using the Arris Surfboard SB6190 DOCSIS 3.0 Gigabit Cable Modem. It was suggested/recommended in here back at that time and am pleased with it. I was recommended a number of hardware components of good quality over the years from others in here and was always very pleased with the suggestions. I am looking to purchase another cable modem, so I have a backup when my Arris dies. I would like another recommendation of a cable modem of good quality, speed, and specs that will see through the possible changes/improvements of cable internet in the future. Any recommendations would be appreciated.
