Our take on the ARRIS SURFboard DOCSIS 3.1 Cable Modem for Xfinity Internet & Voice

The ARRIS SURFboard is a DOCSIS 3.1 cable modem certified for Xfinity Internet and Voice service. It carries a Gigabit Ethernet port for connecting to a router or a single device, and it works with an existing home setup rather than replacing it. DOCSIS 3.1 is the current cable standard, so the modem supports the higher speed tiers Xfinity offers, unlike older DOCSIS 3.0 units that cap out lower. It suits Xfinity customers who want to own their modem instead of leasing one, and who need voice service as well as internet.
