Arris Surfboard SB8200
The SB8200 was the cable modem to buy in 2020 and the hardware still works fine in 2026. DOCSIS 3.1, three years of clean uptime in our test, and the unusual two 1 GbE Ethernet ports for link aggregation. The catch is the missing 2.5 GbE port: on a 1.2 Gbps cable plan it caps you at 940 Mbps unless you set up LAG, which most home routers do not support. Buy the [Motorola MB8611](/reviews/motorola-mb8611) instead unless you find the SB8200 deeply discounted.
