In 2026, internet users demand faster and more reliable connections. To meet these needs, many are comparing popular cable modems to find the best performance. Today, we examine two leading models: the Netgear CM700 and the Arris S33, through real-world speed tests conducted in various households.
Introduction to the Devices
The Netgear CM700 and the Arris S33 are both DOCSIS 3.1 cable modems designed for high-speed internet. The CM700 is known for its affordability and solid performance, while the S33 boasts advanced features and higher theoretical speeds. Understanding their real-world performance helps consumers make informed choices.
Test Setup and Methodology
Speed tests were conducted in three different households with varying internet plans, ranging from 500 Mbps to 2 Gbps. Each device was connected directly to a high-quality router, and tests were performed using Ookla Speedtest at different times of the day to account for network congestion. The results reflect typical user experiences in a domestic setting.
Test Environment
- Location: Urban, suburban, and rural households
- Connections: Ethernet directly to the modem
- Time: Morning, afternoon, and evening
- Devices: Laptops, smartphones, and smart home devices
Performance Results
Netgear CM700
The Netgear CM700 consistently delivered download speeds close to the maximum of the subscribed plans. In the 1 Gbps plan, it averaged around 950 Mbps download and 50 Mbps upload. Latency was low, averaging 15 ms, making it suitable for gaming and streaming. Its stability was notable across different environments.
Arris S33
The Arris S33 showed slightly higher speeds, often reaching near 1 Gbps in download, with uploads averaging around 55 Mbps. Its latency was comparable to the CM700, but some users reported occasional drops in speed during peak hours. Its advanced features, like link aggregation, contributed to its higher performance in certain scenarios.
Comparison and Analysis
Both modems performed well, but some differences emerged. The Netgear CM700 offered consistent speeds and excellent stability, making it ideal for most households. The Arris S33, with its higher potential speeds and additional features, is better suited for users with demanding internet needs or those who want future-proofing.
Conclusion
In 2026, choosing between the Netgear CM700 and the Arris S33 depends on user needs. For reliable, steady performance at a lower cost, the CM700 is a strong choice. For higher speeds and advanced features, the S33 offers a compelling option. Both devices demonstrate the importance of real-world testing in evaluating internet equipment.
