ARRIS announced the SURFboard mAX AX6600 Mesh Wi-Fi 6 System, a Broadcom BCM6755-based design, at CES 2020. In 2019, ARRIS had announced the SURFboard mAX PRO AX11000 for $650 (kit of two) and the SURFboard mAX PLUS AX7800 for $550 (kit of two). The new AX6600-class SURFboard mAX will enter at a lower price point (exact pricing was not announced) to complement the higher-end kits.
Similar to other AX6600-class Wi-Fi 6 mesh designs, the SURFboard mAX also comes with a tri-band configuration (2×2 2.4 GHz for 600 Mbps, 2×2 5 GHz for 1200 Mbps, and a 4×4 160 MHz-wide 5 GHz radio for 4800 Mbps). The 4×4 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.
Availability is slated for Q2 2020, and the pricing ought to be under the $550 mark (given that the mAX PLUS AX7800 kit sells for that). Similar to the other members of the mAX family, the AX6600 version will also be available as a standalone router.
