Similar to other AX6600-class Wi-Fi 6 mesh designs, the SURFboard mAX also comes with a tri-band configuration (2x2 2.4 GHz for 600 Mbps, 2x2 5 GHz for 1200 Mbps, and a 4x4 160 MHz-wide 5 GHz radio for 4800 Mbps). The 4x4 is used as a dedicated backhaul in the mesh kit. ARRIS claims that a kit of two can blanket a 5500 sq. ft. area.
In terms of the internal components, the unit seems similar to the Asus ZenWiFi AX (XT8), but the industrial design and antennae placement (which affects performance) are different. Additionally, the SURFboard mAX AX6600 comes with only two gigabit Ethernet ports per unit (unlike the Asus ZenWiFi which comes with a 2.5 Gbps port). ARRIS also indicated Alexa compatibility for the unit.
