ARRIS SURFboard SB6190 Cable Modem

The ARRIS SURFboard SB6190 is a DOCSIS 3.0 cable modem built for households that receive internet service from providers such as Comcast Xfinity, Time Warner Cable, Wide Open West, Cable One or PenTeleData. It connects to the provider network through a coaxial line and delivers a single Ethernet port for a router or computer.

1.4 Gbps download capacity and headroom

The modem supports theoretical download speeds up to 1.4 Gbps, providing ample headroom for multi-device streaming, large file transfers and online gaming on plans rated well below that ceiling. Performance will taper off when the subscribed plan approaches the DOCSIS 3.0 channel-bonding limit or during peak network congestion.

DOCSIS 3.0 practical limits

The DOCSIS 3.0 standard caps downstream throughput at the stated 1.4 Gbps and cannot match the higher efficiency or upstream symmetry of newer DOCSIS versions. Buyers whose providers require DOCSIS 3.1 for gigabit-tier plans or who need multiple Ethernet ports will need a different device.

Questions about this item

Will the SB6190 work with the older router I already own?

Yes, the modem provides a single RJ45 Ethernet port that connects to any router with a standard WAN port, so your existing hardware can stay in place.

How do I confirm the SB6190 is operating correctly once it is connected?

After activation with your provider, the front-panel LEDs should show solid power, receive, send and online lights, and a wired device should reach the plan’s rated speed.

What cables are included with the SB6190 and what must I supply?

The unit ships with a coaxial cable, an Ethernet cable and a power adapter; you only need an active cable outlet and a router or computer to plug into the Ethernet port.
