The fifth bullet is the reason to choose this over its own stablemates: “Each Deco X55 has 3 Gigabit Ethernet ports (6 in total for a 2-pack) and supports Wired Ethernet Backhaul for better speeds. Any of them can work as a Wi-Fi Router.”
Three sockets a node. The Deco S4 on this shelf gives two, and gets to the same six only by having a third node. For a node standing beside a television, a console and a set-top box, the third socket is the difference between wiring all three and buying a switch — and among the gigabit systems here only the Tenda Nova MW12 and the Deco X50 also give three a node.
The first bullet publishes the class figure properly: AX3000 as 2×2 with HE160 at 2402 Mbps, plus 2×2 at 574 Mbps. Two things are in that line. The arithmetic — 2402 plus 574 is 2976, which rounds to 3000 — and HE160, which is the 160 MHz channel width in its 802.11ax form. The intro to this section says a class figure is the theoretical sum of the radios; this page gives the sum, the terms and the channel width that the larger term depends on. Two streams on each band, published as 2×2.
Four thousand five hundred square feet across two nodes is about 2,250 each, stated in the second bullet, with a capacity of up to 150 devices in the third. A coverage figure divided by its node count is the only readable form, and two nodes covering what three Deco S4 units cover is the Wi-Fi 6 radios doing the work.
Wired Ethernet backhaul is named in the same fifth bullet as the sockets, which is where it belongs: a mesh system with three sockets a node and cable between the nodes is a wired network with wireless attached, and that is the arrangement that actually delivers the figures. The sixth bullet gives AI-driven mesh learning the environment, which is description rather than specification.
The eighth bullet is unusually specific about what the security service includes free: HomeShield with basic network security, quality of service and parental controls, numbered one to three. Naming the free tier matters on a shelf where security subscriptions are common — the NETGEAR router elsewhere on this site offers a thirty-day trial and then charges.
The description gives a two-year warranty and 24/7 support, with the claim of a year more than most networking brands, and notes that the X55 is an upgrade of the X20 with faster speeds and more sockets, suited to connections up to 1 Gbps. That last is a ceiling honestly stated: three gigabit sockets and a gigabit-class service are matched, and a faster line would meet the socket first.
No IEEE clause number appears, so 802.11ax is inferred from Wi-Fi 6. At 400 g (14.1 oz) for the pair — 200 g (7.1 oz) a node — and 110 by 110 by 114 mm (4.49 in), these are the lightest nodes in this group by a wide margin. The description writes “ATandT” where it means AT&T.
