Our take on the ARRIS SURFboard S33 DOCSIS 3.1 Cable Modem

The SURFboard S33 is a DOCSIS 3.1 cable modem with a 2.5 Gbps Ethernet port and a second 1 Gbps port for a separate network. It is approved for cable internet plans up to 1.2 Gbps and bonds 32 downstream and 8 upstream DOCSIS 3.0 channels plus 2x2 OFDM channels. It has no built-in Wi-Fi and no voice support, so you pair it with your own router. It suits households on fast cable plans that want to stop renting a modem; it is more future-proof than DOCSIS 3.0 modems but costs more than basic units.
