Overview
Combining a DOCSIS cable modem and a dual-band WiFi router in one box, the NETGEAR Nighthawk connects straight to a cable line and feeds both wireless and wired devices. It needs activation by the internet provider after setup and is managed through the Nighthawk app or a web browser.
Folding the modem into the router cuts the setup to one box with strong wired options, including a Multi-Gig port and Link Aggregation. Provider support is the limitation: only certain cable operators and plan speeds are listed, and voice bundles are excluded.
Who it's for
Suited to a cable internet home with gaming consoles and desktops that benefit from wired Multi-Gig and Gigabit ports. Households on Verizon, AT&T, CenturyLink, DirecTV or DISH, or with phone service bundled into the plan, should not buy it.
Pros and cons
- Modem and router in one box
- Multi-Gig 2.5 Gig Ethernet port
- Four Gigabit Ethernet ports
- Link Aggregation for a compatible wired device
- Excludes Verizon, AT&T, CenturyLink, DirecTV, DISH
- No bundled voice plan support
- Xfinity support listed only up to 800Mbps
- Needs ISP activation after setup
Performance notes
Download speed is capped first by the cable plan and by the provider limits listed for each operator. DOCSIS OFDMA helps hold speeds steady during peak hours, and devices on the wired ports avoid sharing wireless airtime. Wireless reach depends on walls and placement within the rated coverage area.
