Features – What We Found

Design and Build Quality

The SB8200 has a clean white plastic design that should blend easily with other networking gear. It feels well constructed with adequate ventilation for cooling. The size is compact enough to sit conveniently on a desk or shelf.

On the back it has a coaxial cable connector, Ethernet ports, power port, and reset button. The bottom includes connector status LEDs plus a sticker with the hardware specs and identification details needed to activate it with your internet provider.

Performance and Speeds

Leveraging 32 downstream and 8 upstream channels with DOCSIS 3.1, we measured blazing fast download speeds between 930-960 Mbps over a gigabit cable connection. Upload speeds clocked in around 40-50 Mbps. Of course, actual throughput will depend on your cable provider’s infrastructure.

The SB8200 handled bandwidth-intensive tasks like 4K video streaming, gaming, and video conferencing without any buffering or lag issues. Page load times were lightning quick as well.

Features and Capabilities

Out of the box, the SB8200 acts as just a modem requiring a separate router for WiFi and networking features. The two gigabit Ethernet ports allow connecting routers, switches, computers, game consoles and other wired devices.

Advanced features can be accessed on the browser-based admin interface for monitoring connection status, configuring LAN settings, updating firmware, etc. The SB8200 also works with the SURFboard mobile app for monitoring usage and performing speed tests.

Telephony and VoIP

Since the SB8200 is a straight modem, it has no built-in support for voice/telephony features. You’d need to use adapters or an all-in-one gateway model for VoIP and phone connectivity.


On the security side, it relies on your router for firewall protection, blocking malicious sites, VPN access, and more. We’d recommend adding a router with robust cybersecurity protections.

Concluding Thoughts

With superb speeds, easy installation, and universal cable provider compatibility, the ARRIS SURFboard SB8200 represents an exceptional value for cable internet subscribers. It eliminates equipment rental fees while providing future-proof performance.

The lack of WiFi means you’ll need an extra router, but you’re free to choose one with all the networking capabilities to perfectly match your needs. For pure modem performance, the SB8200 delivers rock-solid reliability making it one of the top options out there.
