Our Verdict

ARRIS SURFboard G36

ARRIS SURFboard G20

The ARRIS SURFboard G20 and ARRIS SURFboard G36 are both DOCSIS 3.1 cable modem and Wi-Fi router combos, but the G20 has an edge in wireless performance. It posts stronger range, faster top speeds, and lower latency, making it the better choice in terms of Wi-Fi connectivity. The G36 offers higher theoretical bandwidth thanks to its upgraded 2.5Gbps WAN port, and it sports five LAN ports (one of which is 2.5Gbps) while the G20 is limited to two. While the G20 is technically smaller, both SURFboards are slim and fit comfortably into tighter spaces.
