Nighthawk AX6000 two-in-one gateway

The Netgear CAX80-100NAS combines a DOCSIS 3.1 cable modem with a Wi-Fi 6 router in a single unit. It replaces a separate modem and router for subscribers who want to stop paying monthly rental fees. The device connects to the provider through a standard coaxial cable and distributes service over wireless and wired links.

Upgrade from DOCSIS 3.0 hardware

Moving from a first-generation DOCSIS 3.0 modem to this DOCSIS 3.1 model can deliver up to 2.5 times faster internet speeds and 10 times faster download performance. The jump is worth it when your provider offers multi-gigabit tiers that older hardware cannot fully utilise. The 2.5 Gbps Ethernet port and dual-port aggregation let you reach up to 2 Gbps wired throughput for compatible clients.

AX6000 wireless capacity and headroom

The dual-band Wi-Fi 6 radio provides 1.2 Gbps on the 2.4 GHz band and 4.8 Gbps on the 5 GHz band using 4x4 streams and 1024-QAM. OFDMA uplink and downlink improve efficiency when many devices are active simultaneously. A 1.5 GHz dual-core processor manages the combined traffic load. The single USB 3.0 port adds basic network storage or printer sharing, while four gigabit ports serve additional wired endpoints.

Questions about this item

What type of coaxial cable connector does the CAX80-100NAS use for the cable line?

It uses a standard female CATV coaxial connector, the same F-type thread used by virtually all North American cable providers.

During setup, which step do users most often miss that prevents the modem from coming online?

After connecting the coaxial cable and power, you must call your ISP and give them the MAC address printed on the label so they can provision the DOCSIS 3.1 modem on their network.

Which component will need attention first if the CAX80-100NAS loses power during a storm?

The external power adapter is the only field-replaceable part; the internal dual-core 1.5GHz processor and DOCSIS 3.1 circuitry have no user-serviceable components.
