Our take on the Arris SURFboard S34 DOCSIS 3.1 Cable Modem

The Arris SURFboard S34 is a DOCSIS 3.1 cable modem built for gigabit and multi-gigabit cable plans. It uses OFDM signaling and two RJ-45 Ethernet ports, so it can feed a router and a second wired device without a separate switch. It is a modem only, with no Wi-Fi, no phone jack and no USB. That makes it a fit for people who already own a good router and want to stop paying modem rental fees; against gateway combos it trades built-in Wi-Fi for cleaner placement and fewer things to reboot. Owners of Arris modems generally praise stable connections and easy activation, though some report units that run warm or need a carrier check before they sync.
