Multi-gig ports on every unit and the largest coverage figure in the budget tier, built on two radios instead of three. That is the whole trade, and it is a better one than it sounds.

Buy the Deco BE25 if you want the most covered floor space you can get in Wi-Fi 7 and you are willing to either wire the nodes together or accept that they will share the 5 GHz band with your devices. Do not buy it if you want 6 GHz, if your house runs more than about a hundred active devices, or if you already own a tri-band mesh that works. It is the cheapest Wi-Fi 7 mesh this site is willing to recommend, and the reason is not the generation badge — it is the two multi-gig ports on every unit, which almost nothing else at this price has.
What TP-Link actually sells here
The Deco BE25 is a dual-band Wi-Fi 7 system. TP-Link's own US specification puts it at BE5000: up to 4,324 Mbps on 5 GHz and 688 Mbps on 2.4 GHz, four streams in total, with 240 MHz channel support and multi-link operation on the 5 GHz band. Coverage is rated at up to 2,600 square feet per unit and up to 6,600 square feet for a multi-pack system, and the system is rated for 150 devices at once. It is sold as a one-, two- or three-pack; the three-pack is the configuration this assessment is written against.
Each unit carries two 2.5 Gbps Ethernet ports with WAN/LAN auto-sensing, so whichever one you plug the modem into becomes the WAN. Backhaul can be wireless or wired over those ports, and TP-Link states the two work together to balance traffic between units rather than the wired link simply replacing the wireless one. Setup runs through the Deco app, the system drops into an existing network as access points if you want it to, and there is a VPN client and VPN server built in.
And then there is the band count. Two radios, not three. That is the number that decides this purchase.
What the missing 6 GHz band actually costs you
In a mesh system, two things compete for airtime: your devices talking to the nearest node, and the nodes talking to each other. A tri-band system can put the second conversation on its own radio. A dual-band system cannot, so every byte a satellite relays is sent twice over the same 5 GHz band — once from your laptop to the node, once from the node to the router.
The honest version of what that costs is: roughly half the throughput on anything connected to a satellite, under load. On a 300 Mbps or 500 Mbps internet plan you will rarely notice, because halving a link that was already faster than your plan still clears your plan. On a gigabit plan in a busy house, you will. How mesh backhaul works walks through the arithmetic, and tri-band vs dual-band mesh is the decision in full.
There is a second cost, and it is the one people forget: 6 GHz is not just a backhaul lane, it is also the band a Wi-Fi 7 phone or laptop uses to hit Wi-Fi 7 speeds. A dual-band Wi-Fi 7 system gives you multi-link operation and wider channels on 5 GHz, which is a real improvement over Wi-Fi 6, but it does not give you the headline numbers from the marketing. If you bought a Wi-Fi 7 laptop specifically for 6 GHz, this is not the system for it.
Try this first
The cable is what makes this system good
The BE25's two 2.5 Gbps ports exist so you can run Ethernet between units. Do that and the dual-band limitation disappears entirely — the nodes stop relaying over the air, each one gets the full connection, and you have a three-radio wired network for the price of a two-radio wireless one. Even one wired hop to the worst-placed node changes the result. Ethernet backhaul for mesh covers how, and whether mesh needs Ethernet at all answers the version of the question people usually ask first.
Where the two 2.5 Gbps ports earn their place
Multi-gig ports at this price are unusual enough to be the headline. Two of them per unit, auto-sensing, is more wired capability than several systems costing twice as much.

Why 2.5 Gbps matters
Who this is for
Modem into the router unit
A gigabit plan cannot pass a full gigabit through a Gigabit port once overheads are counted; 2.5 Gbps clears it with room spare
Anyone on 940 Mbps or faster

Any house with a cable run, or one coax outlet and a MoCA pair
A desk, TV or console into a satellite
One wired device per node, at faster-than-gigabit
A home office or a media cabinet
All three at once
You cannot — there are two ports, and on the router unit one is the WAN

That last row is the practical limitation of the port count, and it is a mild one: an unmanaged 2.5 Gbps switch behind a node costs far less than stepping up a mesh tier. Multi-gig ports explained does the overhead arithmetic if you want to check the claim rather than take it.
Coverage: the 6,600 sq ft figure, read honestly
TP-Link rates the BE25 at up to 2,600 square feet per unit and up to 6,600 square feet whole-home. That is the largest published figure in the budget Wi-Fi 7 tier, and it is genuinely one of the reasons to buy this system — but published coverage figures are measured in conditions your house does not have.
Treat them as a ranking tool rather than a promise. A three-pack rated at 6,600 square feet will do a real 2,500 to 3,500 square foot house well; it will not blanket 6,600 square feet of 1920s lath and plaster. Our sizing method is in how many mesh nodes you actually need, and if your walls are the problem rather than the distance, mesh for thick walls is the more useful page.
The device rating deserves the same treatment. 150 devices at once is a lab number on four internal antennas and a modest chipset. A family house with phones, laptops, a few TVs and a dozen smart plugs is well inside it. A house with thirty cameras is not, whatever the box says — the device-count page explains why airtime, not the association limit, is what actually runs out.
HomeShield: what is free and what is not
TP-Link bundles HomeShield, and the split matters because the app does not make it obvious. Free: the firewall, access control, guest networks, basic network security scanning and basic parental controls. Paid: real-time IoT protection, malicious-site blocking, intrusion prevention and the professional content filtering most people mean when they say parental controls.
If subscription-free features are the thing you care about, that is an argument for ASUS rather than TP-Link — mesh systems with no subscription ranks the field on exactly that, and mesh with the best parental controls is the version for households where that is the whole purchase.
This usually backfires
Do not replace a working tri-band mesh with this
The BE25 is a good first mesh and a good budget upgrade from a single router. It is not an upgrade from a working tri-band system, even an older Wi-Fi 6E one — you would be trading a dedicated backhaul radio for a newer badge and faster ports, and in a wireless-backhaul house that trade usually goes backwards. If your current mesh covers the house and the complaint is speed rather than dead zones, internet fast but Wi-Fi slow will tell you in five minutes whether new hardware is even the fix.

Scroll the table sideways to see every column.
The eero 7 comparison is the one most people are actually making, and we have given it a page of its own: Deco BE25 vs eero 7 is the model-level argument, and eero vs Deco is the brand-level one about software and ecosystems. The short version: eero wins on setup and on smart-home radios, the BE25 wins on rated coverage per dollar, and the port situation is a tie.
Who should buy it
A first mesh for a 2,000-3,000 sq ft house on a sub-gigabit plan. This is the case it is built for, and nothing else at the price does it better.
Anyone who can run one Ethernet cable. Wire a node and the dual-band objection stops applying.
A house that wants Wi-Fi 7 ports more than Wi-Fi 7 radio. The 2.5 Gbps pair will still be useful in five years.
Someone replacing a rented ISP gateway. It drops in behind any modem — replacing your ISP's router covers the per-provider steps.
Who should not
Anyone who bought a device for 6 GHz. There is no 6 GHz radio here at all.
Gigabit-and-above plans with wireless-only backhaul. You will give back half your plan on the satellites. Go tri-band or run cable.
Smart-home-first households. No Thread, no Zigbee, no Matter controller — mesh and smart-home hubs explains when that matters.

Common questions
Is the TP-Link Deco BE25 worth buying?+−
Yes, if you want the most rated coverage per dollar in Wi-Fi 7 and your internet plan is a gigabit or less. TP-Link rates the three-pack at up to 6,600 square feet and puts two 2.5 Gbps auto-sensing ports on every unit, which is more wired capability than several systems costing twice as much. The compromise is that it is dual-band, so satellites relay over the same 5 GHz band your devices use.
Does the Deco BE25 have a 6 GHz band?+−
No. The BE25 is dual-band — 5 GHz and 2.4 GHz only. It is Wi-Fi 7 in the sense that it supports multi-link operation and 240 MHz channels on 5 GHz, but there is no 6 GHz radio, so neither your devices nor the mesh backhaul can use that band. If you need 6 GHz, the tri-band Deco BE63 is the step up inside the same family.
How much area does the Deco BE25 cover?+−
TP-Link rates it at up to 2,600 square feet per unit and up to 6,600 square feet as a multi-pack system. Read those as a ranking figure rather than a promise: published coverage is measured in open conditions, so a three-pack rated at 6,600 square feet comfortably handles a real 2,500 to 3,500 square foot house and will not blanket 6,600 square feet of solid walls.
Can you use Ethernet backhaul with the Deco BE25?+−
Yes, and it is the single best thing you can do to this system. Each unit has two 2.5 Gbps auto-sensing ports, and TP-Link states the wired and wireless backhaul work together to balance traffic between units. Wiring even one node removes the dual-band relay penalty on that node entirely.
Do you have to pay for HomeShield on the Deco BE25?+−
Not for the basics. The firewall, access control, guest networks, basic security scanning and basic parental controls are included. Real-time IoT protection, malicious-site blocking, intrusion prevention and the professional content filtering are the paid tier. If subscription-free features matter to you, ASUS is the brand that includes more of them.
Deco BE25 or Deco BE23 — which should I buy?+−
The BE25, unless the price gap on the day is large. Both are dual-band Decos at the bottom of the Wi-Fi 7 range; the BE25's two 2.5 Gbps auto-sensing ports per unit are the difference, and they are what keeps the system useful on a faster plan or with a wired backhaul later. The BE23 is the right buy only when you are certain the network will stay wireless and sub-gigabit.
