Mesh systems
Two identical nodes, or three units where one is the router and two are satellites?
Both of these are Wi-Fi 7 tri-band systems quoting coverage in the same range, and they are built on different assumptions. The ASUS ZenWiFi BT8 is two identical nodes reaching up to 550 m², with a 6 GHz radio named and up to 14 Gbit/s stated. The NETGEAR Orbi 770 is a router and two satellites reaching up to 540 m², with 11 Gbit/s stated, a named backhaul arrangement, and a qualification the ASUS page does not make.
| Compared on | ZenWiFi BT8, two-node tri-band Wi-Fi 7 set | Orbi 770 Series, router and two satellites, Wi-Fi 7 |
|---|---|---|
| Wi-Fi generation | Wi-Fi 7, in the title and the first bullet | Wi-Fi 7, described as the next generation of speed |
| IEEE designation | Not published — the generation appears by number only | Not published — nine bullets name the generation by number and none prints a letter pair |
| Stated class figure | Up to 14 Gbit/s for the tri-band radios, with MLO and 4K-QAM named; no BE designation, and the figure is not divided between the three radios | Up to 11 Gbit/s, described as 2.4 times faster than Wi-Fi 6, with the maker adding that actual speed depends on the devices and the internet plan |
| Band plan | Tri-band including a 6 GHz radio, named; the individual rates are not given | Tri-band with what the listing calls Enhanced Backhaul; the three frequencies are not named |
| Backhaul type | Not published — AiMesh is named and described as AI-driven, without saying whether a radio is reserved for the link or a cable may carry it | Wireless, named as Enhanced Backhaul within the tri-band arrangement; which radio carries it is not said |
| Node count | Two | Three |
| Pack composition | Two units, with coverage extending further through compatible routers from the same maker | One router and two satellites, not three identical units; a further satellite is said to add up to 180 m² |
| Stated coverage area | Up to 550 m² for the system as a whole | Up to 540 m² on every floor for up to 100 devices, with the maker naming floor plan, building materials and satellite placement as what varies it |
| Ethernet port count | Not published — none of the five bullets counts a socket | Not published — none of the nine bullets counts a socket |
| Port speed | Not published — with no socket counted, no wired speed appears | Not published — readiness for plans up to 2.5 Gbit/s is stated without naming the socket that carries them |
| Separate WAN socket | Not published — nothing identifies which socket the incoming line uses | Not published — the router is stated to connect to an existing modem, and the socket it uses is not described |
A tick means one listing published something the other did not, or published a better figure. It does not mean the product is better, and the column is not a score out of anything: a maker who says less loses lines here without losing a comparison. The two verdicts below are where the page is settled.
The ZenWiFi BT8 is two of the same thing, which matters more than it sounds: either unit can be the one by the modem, and a spare is a spare. It names the 6 GHz radio directly, quotes the higher figure at up to 14 Gbit/s, and carries seven internal antennas. What it will not tell you is how the two units talk to each other — AiMesh is named as AI-driven and the backhaul question is left open, which on a two-node system is the question.
The Orbi 770 is three units where one is the router, so the topology is fixed and a satellite cannot take the router’s place. Against that, it is the more honest page: it names its backhaul, it states the coverage figure with the conditions that change it, and it says the speed depends on the devices and the plan. Its 11 Gbit/s is the lower headline of the two, and it is the one qualified by the maker who printed it.
As a headline, yes; as a promise, neither is one. Both figures are sums across three radios, and no single device connects at either. The Orbi page says so itself, naming the connected devices and the internet plan as what actually decides. The ASUS page prints the larger number and leaves the qualification out — which is why that row goes to NETGEAR.
Coverage, and what happens when one fails. Three units cover more floor between them, and the ASUS pair claims 10 m² more than the NETGEAR trio, so the arithmetic is not simply about counting boxes. With the Orbi, only one unit is the router; with the ZenWiFi, both are the same model. That is a spare-parts argument as much as a coverage one.
Wi-Fi 7 · up to 14 Gbit/s stated · tri-band with 6 GHz · two nodes · 550 m² · seven internal antennas · no socket published
A two-node Wi-Fi 7 set that counts its antennas and its front-end modules and never counts an Ethernet socket.
Best for: A large home with Wi-Fi 7 clients and a wish for separate IoT and guest networks, where the wired side is handled by a switch elsewhere.
≈ £420 / 397 €
Wi-Fi 7 · up to 11 Gbit/s stated · tri-band with Enhanced Backhaul · router plus two satellites · 540 m², qualified by the maker
A three-piece Wi-Fi 7 system whose listing does something rare: it states the coverage figure and then names the three things that change it.
Best for: A multi-storey house of around 540 m² on a fast line, where a router and two satellites are wanted out of one box.
