Main trade-off
TP-Link Deco X20 2-Pack
After an internet cable and one wired satellite are connected, the main unit has no spare Ethernet port.
Head-to-head
TP-Link Deco X20 vs X55: X55 leaves room for both a wired TV and console at the satellite
The short answer
Choose the Deco X55 if a room needs a wired TV and console. The X20 is enough for a simpler two-node layout with one wired device beside the satellite.
Before you choose
The reasoning and the trade-offs
One extra socket avoids a room switch
X55 can connect an uplink, TV and console without an extra box. X20 needs a switch for the same three cables.
What this is based on
Required connections = 1 uplink + 2 devices = 3 ports. X20 has 2, X55 has 3.
Main trade-off
TP-Link Deco X55 3-Pack
Every wired connection is limited to a 1 Gbps link rate.
TP-Link Deco X20 2-Pack
- Choose it for
- You need two nodes and only one wired device in the second room.
- Your internet plan is below a gigabit and there is no multi-gig upgrade planned.
- Main trade-off
- After an internet cable and one wired satellite are connected, the main unit has no spare Ethernet port.
TP-Link Deco X55 3-Pack
- Choose it for
- A wired satellite must also connect a TV and console.
- You want two wired satellite branches from the main unit without adding a switch.
- Main trade-off
- Every wired connection is limited to a 1 Gbps link rate.
About this comparison
Compare Deco X20 and X55 by usable Ethernet sockets, node count and room wiring. See when a third port matters more than a higher Wi-Fi label.

What matters in practice
The differences that matter
One extra socket avoids a room switch
X55 can connect an uplink, TV and console without an extra box. X20 needs a switch for the same three cables.
How we reached this conclusion
Required connections = 1 uplink + 2 devices = 3 ports. X20 has 2, X55 has 3.
A three-node star fits X55 directly
The X55 gateway can connect the internet and two satellites at once. There is no socket left for a local desktop.
How we reached this conclusion
3 ports − 1 internet − 2 satellite links = 0 spare gateway ports.
The faster radio label does not change the wired ceiling
A wired desktop remains on a 1 Gbps physical link with either model.
How we reached this conclusion
Both models specify only 1 Gbps Ethernet ports. Application throughput is lower after overhead.
Check your own setup
Will your wired mesh layout work?
Planning to connect your mesh nodes with Ethernet? Count the sockets before you buy. This checks direct cables from the main node to each satellite, without an extra network switch. These choices are examples until you apply yours.
TP-Link Deco X20 2-Pack
Does not meet these checksThe gateway cannot give your internet connection, 1 direct node link and 1 wired device separate sockets at the selected speeds. A suitable external switch may change that.
TP-Link Deco X55 3-Pack
Meets these checksThe sockets cover this 2-node wired layout, leaving 0 unused gateway LAN sockets. The selected internet-to-device path has a 1 Gb/s link ceiling before overhead, not a promised download speed.
Port speeds are physical link ratings, not Wi-Fi throughput. Cable quality, client adapters and network configuration still matter. All requested nodes must be included in the linked bundle. This assumes router mode with one internet socket and star wiring. PoE units also need a compatible power source, which this socket check does not size. A switch, access-point mode or another layout changes the result. It does not predict wireless coverage.
Choice A
TP-Link, Deco X20
Deco X20 2-Pack
A straightforward two-room starting point when your internet plan is below a gigabit and you do not need several wired devices beside each node.

Meaningful differences
What changes the fit
| What changes | TP-Link Deco X20 2-Pack | TP-Link Deco X55 3-Pack | Why it matters |
|---|---|---|---|
| Ports per node | 2 × 1 Gbps | 3 × 1 Gbps | The third X55 socket is usable capacity, not a higher speed rating. |
| Main unit after internet | 1 spare port | 2 spare ports | X55 can connect two satellite cables directly. |
| Wired satellite after uplink | 1 spare port | 2 spare ports | A TV and console fit directly only on X55. |
| Selected package | 2 nodes | 3 nodes | Compare the total package, not just the model name. |
| 5 GHz channel width | Up to 80 MHz | Up to 160 MHz | A compatible client and usable spectrum are needed to benefit from wider channels. |
| Fastest wired link | 1 Gbps | 1 Gbps | Neither removes a gigabit Ethernet ceiling. |
What you give up
Every choice has a cost
If you choose TP-Link Deco X20 2-Pack
- There is no 6 GHz radio or multi-gigabit Ethernet connection.
If you choose TP-Link Deco X55 3-Pack
- There is no 6 GHz radio and paid HomeShield features remain optional extras.
What matters in practice
How to make the call
Start with the cables in each room
Count the uplink as a device using a socket. A common living-room layout has three cables before you connect anything optional. That makes the X55 easier to live with even if your TV streams at a modest rate.
Buy enough nodes, not the most nodes
Use a unit where it can serve a useful room or floor. Adding a third wireless node beside an existing one does not fix a weak path through a thick wall.
Keep a future faster plan in view
If you already plan to buy a two-gigabit service, compare a Deco with at least two multi-gig ports instead. Replacing the X20 with X55 does not solve that future bottleneck.
What this comparison cannot tell you
- These socket counts assume direct Ethernet backhaul in router mode and no external switch.
- No room coverage or Wi-Fi throughput is predicted from the product class.
