Three Key Takeaways:
The ARRIS SURFboard SB8200 is a DOCSIS 3.1 cable modem built for internet plans up to 2Gbps. It is a modem-only device, meaning you will need a separate Wi-Fi router or mesh system to create a wireless network in your home. By owning this modem instead of renting one from your cable provider, you can eliminate monthly equipment rental fees and reduce your overall internet bill.
DOCSIS 3.1 technology delivers up to 10 times faster speeds than DOCSIS 3.0 and provides lower latency, which is especially helpful for online gaming and video calls. The SB8200 is CableLabs certified and has been tested and qualified for use with Cox, Xfinity, and Spectrum. It is not compatible with fiber, DSL, or satellite internet services. Always check with your provider to confirm that this model is supported on your specific plan before purchasing.
The SB8200 features two 1-Gigabit Ethernet ports. These ports allow you to connect a Wi-Fi router and, if your provider supports it, use a secondary IP address for a separate home or business network. The modem supports both DOCSIS 3.1 OFDM channels (2 downstream x 2 upstream) and DOCSIS 3.0 bonded channels (32 downstream x 8 upstream). It is compatible with both IPv4 and IPv6 standards.
The compact design measures 5.13 inches long by 1.75 inches wide by 5.25 inches tall, making it easy to place on a desk or shelf. LED indicators on the front show power, upstream, downstream, and online status at a glance.
The package includes the SB8200 cable modem, a power supply, a quick-start guide, and a 2-year warranty card. An Ethernet cable is also included for connecting to your router.
Setting up the SB8200 is straightforward. Connect the coaxial cable from your wall outlet to the modem, plug in the power supply, and then download the SURFboard Central app to walk through activation with your cable provider. Once activated, connect a Wi-Fi router to one of the Ethernet ports to set up your home wireless network.
The SB8200 is tested and qualified for use with Cox, Xfinity, and Spectrum. It may also work with other U.S. cable internet providers, but you should contact your provider to confirm support before ordering.
