Overview
A home with cable internet and landline phone service is where the Surfboard gateway fits, combining a cable modem, a Wi-Fi router and two phone lines in one box. MoCA shares the connection over existing coax, and battery backup support helps voice service ride out outages.
Combining modem, router, MoCA and voice ports cuts the number of boxes and cables at the cable outlet. The Wi-Fi standard is a generation behind current routers, so large homes may still want a separate mesh system.
Who it's for
Households with cable internet and home phone lines get one gateway for data, voice and coax networking. Buyers who only need internet with the latest Wi-Fi should look at a separate modem and router.
Pros and cons
- Modem, router and phone in one
- Four Gigabit Ethernet ports
- MoCA networking over coax
- Battery backup support
- Wi-Fi 5, not Wi-Fi 6
- Provider compatibility not listed
Performance notes
The modem bonds many downstream channels and OFDM blocks to reach gigabit-class speeds on a cable line. Separate radios for each band, with more antennas on the faster band, spread Wi-Fi capacity across devices. MoCA uses existing coax wiring to carry the network to rooms Wi-Fi reaches poorly.
