ARRIS SURFboard S33 DOCSIS 3.1 Modem

The ARRIS SURFboard S33 is a sleeker design than all of the prior SURFboard modems. The S33 is a DOCSIS 3.1 cable modem capable of multi-gig speeds up to 2.5 Gbps. This is accomplished by using link aggregation, basically by linking both Ethernet ports together.

With CommScope now owning the ARRIS brand name, the design and enclosure of the SURFboard S33 have a sleeker design. It’s clear they are trying to mix things up a little bit and for the better. In addition to the newer design, the S33 features the latest DOCSIS technology, DOCSIS 3.1. This makes this cable modem perfect for gamers and streaming fanatics. Couple the S33 with a WiFi-6 router and you’ll be on top of the tech game. The S33 is ideal for XFINITY, COX, Spectrum, and other major ISPs with 1 Gbps speeds or higher. This modem is backward compatible with 3.0 and lower speeds. However, buying a 3.1 modem ensures you’ll be ready for any future upgrades. MSRP: $199.99
