Arris Cable Modem with Wifi Routers

Before releasing this Surfboard sbg8300 series, Arris had released few series of cable modem wireless router products including two series of Surfboard Sbg7400 and Sbg7600. These three products are cable modems with different speeds but have similarities in wireless routers integrated into this wireless gateway product, namely wave 2 wifi AC2350 simultaneous dual band. Technically, each model delivers wifi speeds of up to 1733Mbps @5GHz and up to 600Mbps @2.4GHz band.

What the differences?

The main differences lie on the types of cable modem and speeds each of the Surfboard cable modem that is integrated into the wireless router. Take a look at the following table. Both Surfboard Sbg7400 and Sbg7600 are DOCSIS 3.0 cable modem; however the Arris Sbg8300 is DOCSIS 3.1 which the speed is 10 times faster than DOCSIS 3.0.

The second difference is the number of channel bonding for downstream internet speed. Sbg7600 is designed with 32x channel bonding with speed up to 1.23Gbps, a bit different with Sbg7400 which is only 24x channel bonding. Since DOCSIS 3.1 cable modem is backward compatible with any existing DOCSIS 3.0 infrastructure, investing Sbg8300 is worth for blasting speed of internet plan up to 4Gbps.
