ARRIS SURFboard G34 vs SURFboard G18

The ARRIS SURFboard G34 is slightly better than the ARRIS SURFboard G18 overall. Both are DOCSIS 3.1 cable modems and Wi-Fi 6 router combos, but the G34 has a slight edge in speed, range, and wired flexibility, with four 1Gbps LAN ports compared to the G18's two. The G18 is smaller and does a bit better for wireless latency, so it's still a solid choice for simpler setups or casual gaming over Wi-Fi. However, the G34 is the more practical choice if you need stronger long-range coverage or more room for wired devices. Neither model supports native mesh expansion, so both are less ideal for homes that need expandable coverage.
