Arris Surfboard S34 Cable Modem | DOCSIS 3.1 & Next-Gen Speed

Unlock the Full Potential of Your High-Speed Internet Plan

Upgrade your home network with the Arris Surfboard S34, the next-generation cable modem designed for speed, stability, and future-proofing. Built with the latest DOCSIS 3.1 technology, the S34 is engineered to handle the ultra-fast multi-gigabit download speeds and enhanced upload speeds offered by modern cable providers. Whether you are a competitive gamer, a 4K streamer, or working from home, the S34 eliminates bottlenecks to deliver a lag-free, premium internet experience.

Next-Gen Upload Speeds

Unlike older modems, the Arris S34 is optimized for Next-Gen upload speeds. It supports "mid-split" technology, which allows it to access higher upstream frequency bands. This makes it one of the few modems capable of unlocking faster upload tiers on supported networks (such as Xfinity’s Next Gen speed plans), ensuring your video calls are crisp and your large file backups happen in seconds.

Multi-Gig Ethernet Ports for Maximum Throughput

Flexibility is key for a high-performance setup. The S34 features two distinct ethernet ports:

• 1 x 2.5 Gbps Port: Connect this directly to a Wi-Fi 6E or Wi-Fi 7 router to blanket your home in multi-gig speeds.

• 1 x 1 Gbps Port: Perfect for a dedicated hardline connection to a gaming PC, console, or secondary network device.

Universal Compatibility & Savings

Stop renting improved performance. Owning the Arris S34 allows you to replace your ISP’s rental gateway, saving you up to $168 per year in equipment rental fees. It is certified for use with major U.S. cable internet providers, including Xfinity (Comcast), Cox, Spectrum, and others.

Compact, Heat-Efficient Design

The S34 features a sleek, compact white chassis that fits easily on any shelf or desk. Its vertical design is engineered for passive cooling, ensuring the modem stays cool even during data-intensive tasks like simultaneous 4K streaming and large game downloads.
