All-in-one DOCSIS 3.1 gateway

The ARRIS G34 combines a DOCSIS 3.1 cable modem with a Wi-Fi 6 AX3000 router in a single unit. It connects via a standard CATV coaxial connector and provides four 1 Gbps Ethernet ports for wired devices. The SURFboard Central App handles setup and ongoing management. It is certified for cable internet speed plans up to 1 Gbps.

Home users on gigabit cable plans

This gateway suits households that want to replace a rented modem-router combo with owned hardware supporting DOCSIS 3.1 and Wi-Fi 6. It works with major U.S. providers such as Cox, Spectrum and Xfinity. Buyers who need more than four wired ports or a dedicated multi-gigabit uplink should consider a separate switch or a gateway with higher-speed Ethernet. Advanced users requiring bridge mode only or separate upgrade paths for modem and router may prefer discrete units.

DOCSIS 3.1 with 2x2 OFDM channels

The modem uses 2 downstream by 2 upstream OFDM channels under DOCSIS 3.1, alongside 32 downstream by 8 upstream DOCSIS 3.0 channels. This channel configuration determines the maximum throughput available from the cable plant. Verify that your provider provisions this OFDM profile for your speed tier before purchase.

Questions about this item

Does the CATV-Coaxial connector on the ARRIS G34 require periodic replacement or maintenance?

The coaxial connector is a passive interface with no moving parts and no specified maintenance interval; it remains functional as long as the cable is undamaged and properly tightened.

What is the maximum sustained throughput the four 1 Gbps Ethernet ports can deliver before hitting a bottleneck?

Each port is rated at 1 Gbps, so the wired ceiling is 1 Gbps per port; the DOCSIS 3.1 link also tops out at 1 Gbps, making that the first limit under sustained load.

How much heat or fan noise does the G34 produce when running continuously at full 1 Gbps throughput?

The unit uses passive cooling with no fan, so it generates no fan noise; surface warmth increases under load but stays within normal operating limits for a fanless gateway.
