The catch
TP-Link Deco X20 2-Pack
The main unit runs out of Ethernet ports as soon as the internet cable and one wired satellite are hooked up.
Side by side
TP-Link Deco X20 vs X55: At the satellite, X55 has space for a wired TV and a console together
Quick verdict
A room with a wired TV and console calls for the Deco X55. The X20 is enough for a simpler two-node layout where one wired device sits next to the satellite.
Before you buy
Why, and what it costs you
A room switch is avoided with one extra socket
An uplink, TV and console can all connect to X55 with no extra box. For the same three cables, X20 needs a switch.
Where this comes from
1 uplink + 2 devices = 3 ports required. X20 offers 2, X55 offers 3.
The catch
TP-Link Deco X55 3-Pack
No wired connection can link faster than 1 Gbps.
TP-Link Deco X20 2-Pack
- Why pick it
- Two nodes are enough for you, and the second room has just one wired device.
- You have no multi-gig upgrade planned, and your internet plan sits below a gigabit.
- The catch
- The main unit runs out of Ethernet ports as soon as the internet cable and one wired satellite are hooked up.
TP-Link Deco X55 3-Pack
- Why pick it
- A TV and console have to connect through the wired satellite too.
- You want to run wired branches to two satellites from the main unit and skip the switch.
- The catch
- No wired connection can link faster than 1 Gbps.

What this page compares
Usable Ethernet sockets, node count and room wiring decide between Deco X20 and X55. In some homes a third port matters more than a higher Wi-Fi label.

In practice
Differences you will notice
A room switch is avoided with one extra socket
An uplink, TV and console can all connect to X55 with no extra box. For the same three cables, X20 needs a switch.
How we worked this out
1 uplink + 2 devices = 3 ports required. X20 offers 2, X55 offers 3.
X55 can handle a three-node star directly
At once, the X55 gateway can connect the internet and two satellites, and then no socket remains for a local desktop.
How we worked this out
0 spare gateway ports = 3 ports − 1 internet − 2 satellite links.
A faster radio label leaves the wired ceiling where it was
With either model, a wired desktop stays on a 1 Gbps physical link.
How we worked this out
1 Gbps Ethernet ports are all that either model specifies, and application throughput is lower after overhead.
Plug in your setup
Can this mesh kit handle your wired layout?
Wiring your mesh nodes together with Ethernet? Count the ports before you buy. This checks direct cables from the main unit to each satellite, with no extra network switch. These answers are placeholders until you apply your own.
TP-Link Deco X20 2-Pack
Fails these checksThe gateway does not have enough ports at your chosen speeds for your internet line, 1 direct node link and 1 wired device. A suitable external switch could change that.
TP-Link Deco X55 3-Pack
Passes these checksThe ports cover this 2-node wired layout with 0 gateway LAN ports to spare. Your internet-to-device path tops out at a 1 Gb/s link ceiling before overhead, which is not a promised download speed.
Port speeds are physical link ratings. They do not measure Wi-Fi throughput. Cable quality, client adapters and network settings still matter. Every node you plan on must come in the linked bundle. This assumes router mode with one internet port and star wiring. PoE units also need a compatible power source, which this port check does not size. A switch, access-point mode or a different layout changes the result. It does not predict wireless coverage.
Option A
TP-Link, Deco X20
Deco X20 2-Pack
If your internet plan is below a gigabit and you do not need several wired devices next to each node, this is a simple way to cover two rooms.
- Best for
- One wired device in the second room on a modest internet plan
Facts we checked
- Each unit has two Gigabit Ethernet ports, and WAN and LAN roles are assigned automatically.
- Wi-Fi 6 here is dual-band, on 2.4 GHz and 5 GHz.
- Ethernet backhaul is supported, and the selected package has two units.
Option B
TP-Link, Deco X55
Deco X55 3-Pack
A wired home with a TV and console in the same room gets good use from the three Ethernet sockets on each unit.
- Best for
- A gigabit network where a TV and console plug in next to a wired satellite
Facts we checked
- Each unit has three Gigabit Ethernet ports, with WAN and LAN roles assigned automatically.
- Wi-Fi 6 is dual-band, and the 5 GHz band supports 160 MHz.
- The selected package comes with three units, and Ethernet backhaul is supported.
Spec by spec
Where they really differ
| Spec | TP-Link Deco X20 2-Pack | TP-Link Deco X55 3-Pack | In practice |
|---|---|---|---|
| Ports per node | 2 × 1 Gbps | 3 × 1 Gbps | X55's third socket adds usable capacity and not a higher speed rating. |
| Main unit after internet | 1 spare port | 2 spare ports | Two satellite cables can plug straight into X55. |
| Wired satellite after uplink | 1 spare port | 2 spare ports | Only X55 can take a TV and console directly. |
| Selected package | 2 nodes | 3 nodes | Look at the whole package and not only the model name. |
| 5 GHz channel width | Up to 80 MHz | Up to 160 MHz | Wider channels only help with a compatible client and usable spectrum. |
| Fastest wired link | 1 Gbps | 1 Gbps | A gigabit Ethernet ceiling stays in place on both. |
Trade-offs
What each pick costs you
With TP-Link Deco X20 2-Pack
- It offers neither a 6 GHz radio nor a multi-gigabit Ethernet connection.
With TP-Link Deco X55 3-Pack
- Paid HomeShield features are optional extras, and there is no 6 GHz radio.
Decision guide
How to decide
Room-by-room cable count comes first
Treat the uplink as a device that takes up a socket. In a typical living room, three cables are already in place before anything optional gets plugged in. Even if your TV streams at a modest rate, that makes the X55 easier to live with.
Enough nodes beats the most nodes
A unit earns its place by serving a useful room or floor. A weak path through a thick wall is not repaired by a third wireless node placed beside an existing one.
Think about a faster plan down the road
Compare Deco models with at least two multi-gig ports instead if you already intend to get a two-gigabit service. Swapping the X20 for the X55 leaves that future bottleneck in place.
What this page can’t tell you
- Counting sockets this way presumes router mode, Ethernet backhaul run straight between units and no external switch.
- Product class alone cannot forecast room coverage or Wi-Fi throughput.
