The catch
TP-Link Deco X55 Pro 3-pack
Wireless backhaul has to share the 5 GHz radio with your clients, since there is no 6 GHz band.
Side by side
Deco X55 Pro vs Deco XE75: X55 Pro keeps the wired path at 2.5Gb while XE75 gives a 6GHz wireless route
Quick verdict
Every node on X55 Pro has two 2.5Gbps ports, which makes it the stronger wired value. XE75 wins on the wireless side if nearby Wi-Fi 6E clients or a 6 GHz mesh path matter more to you than multi-gig Ethernet.
Before you buy
Why, and what it costs you
The catch
TP-Link Deco XE75 3-pack
Wired traffic maxes out at one gigabit because all three Ethernet ports on each node are gigabit.
TP-Link Deco X55 Pro 3-pack
- Why pick it
- You can run Ethernet backhaul
- You already have a 2.5Gbps switch or NAS
- The catch
- Wireless backhaul has to share the 5 GHz radio with your clients, since there is no 6 GHz band.
TP-Link Deco XE75 3-pack
- Why pick it
- 6 GHz serves your Wi-Fi 6E clients
- Most traffic rides on wireless backhaul
- The catch
- Wired traffic maxes out at one gigabit because all three Ethernet ports on each node are gigabit.

What this page compares
Wi-Fi 6 with 2.5Gbps ports versus Wi-Fi 6E with 6 GHz.
This one comes down to bands and ethernet first, then to the limits of your own setup.
Day to day
How each one fits your routine
Adding a console next to the work computer changes the cheaper layout
XE75 can take the backhaul, computer and console directly at a wired bedroom satellite. X55 Pro has only one client socket left after backhaul and needs a switch for the same arrangement. Choose XE75 if both clients need only gigabit and skipping another box matters. Choose X55 Pro for a faster wired client, and count the switch cost and a power outlet.
Where this comes from
Each XE75 unit has three gigabit sockets, and X55 Pro has two 2.5GbE sockets. On the satellite, backhaul uses up one of them.
The 6 GHz label can't make a wired NAS path faster
With a 2.5GbE NAS and desktop in different wired rooms, X55 Pro is the relevant starting point, provided every intermediary supports that rate. XE75 adds a 6 GHz radio, but its gigabit Ethernet sockets stay in the cable route. Choose XE75 for a compatible wireless-client plan and not to speed up that wired NAS transfer. Choose X55 Pro when the hardwired path is the real bottleneck.
Where this comes from
Radio bands describe one segment and Ethernet link rates another. XE75 has 6 GHz and gigabit ports, whereas X55 Pro has 2.5GbE ports and no 6 GHz radio.

Pick the situations that sound like you
I can run Ethernet between the mesh nodes
TP-Link Deco X55 Pro 3-pack lists “Two 2.5Gbps ports” for ethernet, while TP-Link Deco XE75 3-pack lists “Three 1Gbps ports”. For ethernet, this affects what you can connect and how data can move. A higher rating on the label does not guarantee the same real-world result in every 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 X55 Pro 3-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 XE75 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.
