Our take on the ARRIS Surfboard DOCSIS 3.1 Multi-Gigabit Cable Modem

The ARRIS Surfboard S33 is a DOCSIS 3.1 cable modem with a 2.5 Gbps Ethernet port and a second 1 Gbps port, for combined download speeds up to 3.5 Gbps. It is the fastest modem in the Surfboard line and is meant for cable plans above 1 Gbps where a basic modem would bottleneck the connection. Unlike gateway units it has no built-in Wi-Fi, so you pair it with your own router. Owners rate it well overall, though some report units that failed early or ran hot.

Questions and answers

Does the S33 work with my cable provider?
It is certified for major US cable providers that support DOCSIS 3.1. Check your provider's approved modem list before buying, since some fiber and DSL services do not use cable modems.
Do I need a separate router?
Yes. The S33 is a modem only, with no Wi-Fi. You connect a router or mesh system to its Ethernet ports for wireless coverage.
Will it give me faster internet than my current modem?
Only if your cable plan is faster than what your current modem supports. Plans under 1 Gbps will not benefit from the 2.5 Gbps port.
What is in the box?
The modem, a power adapter, an Ethernet cable and a quick start guide.
Is it better than the S32?
The S33 adds a 2.5 Gbps Ethernet port for multi-gigabit plans. The S32 tops out at 1 Gbps, so the S33 is the better pick only for faster plans.
Can I use both Ethernet ports at once?
Yes, but only one device per port. The 2.5 Gbps port serves your router, and the 1 Gbps port can feed a second wired device.
