Our take on the ARRIS SURFboard SB6183 Cable Modem

The ARRIS SURFboard SB6183 is a DOCSIS 3.0 cable modem rated for up to 686 Mbps downstream across 16 bonded channels and 4 upstream channels. It is a wired-only modem with a single Gigabit Ethernet port, no built-in router or Wi-Fi, so it pairs with a separate router or mesh system. It suits households on mid-tier cable plans from Comcast and Cox who want to stop renting a modem and own their equipment. Against DOCSIS 3.1 rivals it tops out lower, so it is a poor fit for gigabit plans, but for plans under roughly 400 Mbps it does the same job for less.

Questions and answers

Does the SB6183 work with gigabit internet?
No. It is DOCSIS 3.0 with a 686 Mbps downstream rating, so it suits plans below that. Gigabit plans need a DOCSIS 3.1 modem.
Do I need a separate router?
Yes. The SB6183 is a modem only, with one Ethernet port and no Wi-Fi. You connect a router or mesh system to it.
Which providers support it?
It is listed for Comcast and Cox. Check your provider's approved modem list before buying, since support varies by plan.
How many devices can I connect directly?
One, through the single Gigabit Ethernet port. More wired devices require a router or switch.
Is it better than a DOCSIS 3.1 modem?
Only if your plan is below its speed rating and you want to spend less. A 3.1 modem is more future-proof and needed for faster tiers.
