ARRIS SB8200 DOCSIS 3.1 Cable Modem

The ARRIS Surfboard SB8200 is a DOCSIS 3.1 cable modem built for residential broadband. It delivers download speeds up to 5Gbps and upload speeds up to 262Mbps through 32 download channels and 8 upload channels. Two Gigabit Ethernet ports provide wired connectivity for routers or devices. The unit supports IPv4 and IPv6 standards.

Suitable for High-Speed Cable Plans

This modem suits households with gigabit-tier cable subscriptions who want to avoid rental fees and need low latency for 4K streaming or VR gaming. It is not for buyers on DSL or fibre networks, nor for users whose provider does not support DOCSIS 3.1 activation. It also lacks built-in Wi-Fi, so a separate router is required for wireless access.

DOCSIS 3.1 with 32x8 Channel Bonding

The decisive specification is DOCSIS 3.1 with 32 downstream and 8 upstream bonded channels. This configuration enables the multi-gigabit download ceiling that separates the SB8200 from older DOCSIS 3.0 models limited to lower channel counts. Confirm your ISP provisions this channel set before purchase.

What type of internet service must I already have for the ARRIS Surfboard SB8200 DOCSIS 3.1 Cable Modem, 1000205 to work?

Yes, connect any router to one of the two Gigabit Ethernet ports and it will handle Wi‑Fi and wired devices as before.

How do I confirm the ARRIS Surfboard SB8200 DOCSIS 3.1 Cable Modem, 1000205 is operating at its rated 5Gbps download capability?
