SURFboard® Cable Modems

Why own your modem?

Most people that lease equipment from their Internet Service Provider (ISP) keep their modem for several years. Renting a modem from your ISP can cost an average of $100 per year. In just this amount of time you could own your own modem, one with better performance and faster speeds. So stop leasing and start saving today! People tend to upgrade their routers more often than their modems. Why? Because they typically purchase this equipment on their own and when speeds slow down, many people assume it’s the router. The modem is the backbone of a home network. Upgrading the router and the modem together, will ensure your home network is running at peak performance.

Which products are compatible with my modem?

All SURFboard products are compatible with all U.S. Cable providers.

What's the difference between 802.11n and 802.11ac Wi-Fi?

Today’s wireless products are based on either 802.11n or 802.11ac radio standards. Devices may have one, two or three radios: 2.4 GHz, 5 GHz, or dual 5 GHz. These configurations may be designed to work as one or the other, or a dual-band or tri- band concurrently operating radios.

802.11ac is the newest technology and offers the best throughput potential. Beamforming is also a feature supported by 802.11ac radios. This technology focuses the radio signals on the client device location for better performance.

Depending on the device’s antenna configuration you Wi-Fi throughput will vary for each standard. Examples of throughputs:

  • 2.4 GHz with 802.11n 2×2 antennas = 300 Mbps
  • 2.4 GHz with 802.11n 3×3 antennas = 450 Mbps
  • 2.4 GHz with 802.11ac 3×3 antennas = 600 Mbps
  • 5 GHz with 802.11ac 2×2 antennas = 900 Mbps
  • 5 GHz with 802-11ac 3×3 antennas = 1300 Mbps
