Product details

Unlock ultra-fast home internet with DOCSIS 3.1

The ARRIS SURFboard SB8200 is built for modern cable plans, delivering robust data throughput up to 2 Gbps on compatible service tiers. If you crave smooth 4K streaming, quick file downloads, and low-latency gaming, this modem is designed to handle the demands of today and tomorrow without relying on a built-in router.

Ownership can reduce ongoing charges from rental equipment. When paired with a router, the SB8200 becomes the backbone of your home network, giving you control over firmware updates, security settings, and Wi‑Fi performance that suits your household.

Key benefits you might notice

  • DOCSIS 3.1 technology supports cable plans up to 2 Gbps, enabling fast data delivery for streaming, gaming, and downloads.
  • Owning the modem can help you avoid monthly rental fees while remaining compatible with many service providers.
  • A compact, modern chassis fits neatly on a shelf or desk, with discreet LED indicators for power, upstream, downstream, and online status.

What to expect during setup

  • Simple connection: attach the coax, power it up, and activate through your cable provider. Then link a router to the Ethernet port to extend Wi‑Fi coverage.
  • This is a modem‑only device; a separate Wi‑Fi router or mesh system is required to enable wireless networking in your home.
  • Two 1 Gbps Ethernet ports give you the option to connect a router directly or pair with a network switch for wired devices.

Notes on compatibility

All SURFboard modems are designed to work across major US providers and have been tested for compatibility with brands like Xfinity, Cox, and Spectrum. If you have a fiber, DSL, or satellite service, this modem will not apply to those connections. Always check with your provider to confirm device support before purchasing.
