ARRIS S33 INFO

Supported by most major cable ISPs, the ARRIS S33 DOCSIS 3.1 cable modem is one of the best options available on the market. Maximize your years of use from a cable modem by purchasing a DOCSIS 3.1 modem (the latest standard). Eventually, all DOSCIS 3.0 modems will become obsolete (end-of-life).
