How does internet arrive?

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

  • The CAX30 is a lower-spec AX2700 combo, not a capacity variant of the CAX80.
  • The CAX80 has no mesh capability on its own; NETGEAR sells separate mesh extenders.

Why people pick it

  • Combines a DOCSIS 3.1 modem and an 8-stream Wi-Fi 6 router in one box, removing the monthly modem rental fee
  • A 2.5 Gbps Ethernet port handles multi-gig cable plans that a normal Gigabit port would cap
  • USB 3.0 storage sharing and VPN support are built in, plus the Nighthawk app for setup

Know before you buy

  • No support for cable bundled voice services, so a phone line from the cable company needs the provider's equipment or an Ooma-style device
  • Wi-Fi 6 rather than Wi-Fi 7, and 6 Gbps is the combined theoretical rate, not real-world throughput
  • Large desktop-only tower with internal antennas, not wall-mountable
