How does internet arrive?

The cable coming into your home decides what belongs here.

Start with the service

A modem is not a Wi-Fi upgrade.

A DOCSIS cable modem translates cable service to Ethernet. Your router handles your home network.

The trap to avoid

A cable modem does not replace a fiber ONT or a DSL modem.

Watch out

  • SURFboard model numbers differ by DOCSIS speed tier and Wi-Fi; the model number on the front label is the one to match.

Why people pick it

  • One 10 GbE port plus four 1 GbE ports, so a fast wired network does not need a separate router
  • Built-in BE18000 Wi-Fi 7 covers the whole home in one box (maker claims up to 5,000 sq ft)
  • DOCSIS 3.1 modem rated for cable plans up to 2.5 Gbps, compatible with the major U.S. cable providers

Know before you buy

  • No digital voice support, so it cannot replace a provider's phone service
  • The maker rates it for plans up to 2.5 Gbps even though it has a 10 GbE port
  • Only a 1 year limited warranty, shorter than the 2 years on SURFboard stand-alone modems
