Manufacturer description

SpecPicks Verdict

SpecPicks scored ARRIS Surfboard G34 DOCSIS 3.1 Cable Modem & Wi-Fi 6 Router using a rating × review-volume × price-fit model applied to published specs and reviews across the networking category. ARRIS's networking lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Frequently Asked Questions

Will the ARRIS G34 work with my cable provider?

It is CableLabs certified and specifically tested and qualified for Cox, Xfinity, and Spectrum. Confirm your provider supports the G34 model before buying, and note it does not work with fiber, DSL, or satellite service.

How fast an internet plan can the G34 handle?

The DOCSIS 3.1 modem supports cable plans up to 2.5 Gbps. Wired devices connect through four 1 Gigabit Ethernet ports, so any single wired device is capped at 1 Gbps.

Does buying this actually stop my modem rental fee?

Yes, once your provider activates the G34 as your own equipment and you return theirs. Check with your provider first to confirm plan and model compatibility before returning rented hardware.

How much of my house will the Wi-Fi cover?

The AX3000 dual-band Wi-Fi 6 radio is rated to cover up to 2,500 square feet and deliver up to 3 Gbps of wireless performance. Larger or multi-story homes may need additional access points.

Is setup difficult if I have never installed a modem?

Connect the coax cable, power the unit on, and activate it with your cable provider. You can then join the default Wi-Fi network or set your own network name and password; LEDs show power, upstream, downstream, and online status.
