TP-Link Deco XE75 Wi-Fi 6E AXE5400 Tri-band Mesh router (network review)

The TP-Link Deco XE75 Wi-Fi 6E AXE5400 is the first tri-band mesh router we’ve tested. The review helps us understand the nuances of Wi-Fi 6E and the differences between how different brands handle Wi-Fi 6E mesh.

In the case of TP-Link, it is a tri-band 2.4/5/6GHz router that uses the 6GHz band for mesh backhaul to the router. While it’s great to use the uncongested and faster 6GHz band for backhaul, the trade-off is that the satellites need to be closer to the router, especially when the signal passes through walls, doors, closets, etc.

Our testing has confirmed that around 7 meters is the maximum satellite/router distance, but we still got acceptable results up to 10 meters.

An XE75 Pro is coming. The main difference is a 2.5GHz Ethernet port replacing one of the three Gigabit ports.

We use Fail (below expectations), Pass (meets expectations), and Exceed (exceeds expectations or is best in class) for many of the following. Occasionally we give a Pass(able) rating, which isn’t as good as it should be, and a Pass ‘+’ rating to show it’s good but doesn’t quite make it to Exceed.

First impression – passed

After reviewing the stylish Art Deco-shaped TP-Link Deco X90 AX6600 mesh router, it’s fast, very fast (review), I was a bit disappointed with the rather squat cylinder design. It’s not ugly by any means, but I wouldn’t make it a feature like I would on the X90.

Setup – a breeze – Exceed

The 3-pack contains three identical devices. Whoever you connect to the internet becomes the router. The LAN port (there are three) you use will automatically become a WAN port.

Download the TP-Link Deco app for Android or iOS, connect the first “router” and as soon as the LED flashes blue, the app takes over. You need a TP-Link account and there are no obvious privacy issues. The admin password is your account password. Enter the SSID name and password and give the first device a location such as “office”. Language assistants also use this location.

Adding a satellite is also easy. Switch it on near the router and the app will find it and set it up – the same goes for a room. Once added, you can move the satellite to the new location and optionally use Ethernet backhaul by simply plugging a cable back into the router.

The app does not have an indicator of the signal strength between the satellite and the router, so pay attention to the distance. If a satellite fails to network using Wi-Fi 6E backhaul, you may see a blinking red LED.

The app is simple – it lists clients on the network or is connected to each satellite. There is a scan function and channel optimization (HomeShield free)

mesh smarts

As I used the system more, I realized how TP-Link does a lot of things automatically – hence its simple interface. For example:

  • It can swap and change traffic across the 2.4 and 5 GHz bands (Adaptive Path Selection)
  • It can aggregate unused bandwidth to get 2400Mbps connection
  • Self-healing when other routers nearby are using the same bands
  • Bluetooth and Zigbee as well as WLAN (IoT Mesh)
  • Supports other IEEE 802.11.11k/v/r mesh devices
  • 2 x smart antenna and beamforming between router and satellites
  • Its AI-driven mesh is among the fastest I’ve seen for roaming handover to satellites – about 2 seconds is all it takes.
  • Has a stateful packet inspection firewall (no need to disable gateway firewall, DHCP or NAT).

device support

TP-Link claims to have up to 200 connected devices, and that’s theoretically possible. But the reality is more like 30-40 if you have Wi-Fi hungry devices like security cameras and 4K streaming.

Pros and cons of 6GHz Wi-Fi backhaul

  • Fast and largely undisputed
  • Maximum distance between satellite and router 5-7m unless Ethernet backhaul is used
  • In AU only 3 x 160 MHz channels and lower transmission power (USA 7 x 160 MHz)

Test: Router only.

Samsung S22 Ultra. -dBM – lower is better. Mbps – higher is better. Ms – lower is better. Maximum NBN speed is nominally 100/20.

5GHz -dBm/Mbps 6GHz -dBm/Mbps 5GHz DL/UL/Ms 6GHz DL/UL/Ms
2 -28/2401 -33/2041 10/20/21 10/16/21
5 -44/1725 -50/1361 10/20/28 10/15/25
10 -50/1300 -63/524 10/20/29 10/13/27
fifteen -55/897 -68/433 10/17/33 100/12/49
5m through 2 walls and cabinets -65/1814 -68/272 10/17/44 10/15/99

Conclusions: The 6GHz band exceeds -60dBm (becomes unusable) before 10m, although it still has enough power to drop the full NBN 100Mbp DL and UL speeds. The 5 meter through wall test proves that the 6 GHz band is best in sight.

This confirms our observations with the Netgear RAXE500 AXE11000, Wi-Fi 6E router (network test).

Tests: satellites

We retested 10m from the router and the results were about 30% lower in Mbps and much longer ping times.

daisy chain

We tested a Wi-Fi 6 GHz backhaul satellite>satellite>router and while the satellite transmission speeds were identical, the throughput at the farthest point (15m) from the router dropped about 30%. That’s fine as it still matches NBN speeds, albeit at 70-90ms ping times.

Conclusions: The satellites work well with Wi-Fi 6E backhaul, but we recommend no more than 7 meters line-of-sight or 5 m through walls, closets, etc. If you use Wi-Fi 6E backhaul, you will get about 360 Mbps of the 6 GHz bandwidth, hence the difference between 5 GHz 2401 and 6 GHz 2014 Mbps.

Ethernet backhaul gives the Wi-Fi 5 and 6 GHz channels 2401 Mbps, reducing ping latency.

In any case, all configurations could deliver almost the full NBN UL/DL, with the main difference being in the ping times.

Effective Distance/Area – Pass

Typically 2.4GHz can span 30-40m site line and doesn’t lose much through walls. 5GHz at around 10-15m (around 20% loss through walls) and 6GHz at 5-7m. You will need extenders or a mesh system if you want full coverage of the house.

The caveat here is using Wi-Fi 6E backhaul, and we recommend keeping the satellites at 7m.

That means the coverage is as follows

<7 Meter>satellite<7 Meter>routers<7 Meter>satellite<7 Meter> or 28m length x 14m diameter 392m2.

Well, that’s a little at odds with TP-Link’s 650m2, but remember that Australia’s 6GHz transmit signal strength and 480MHz contiguous bandwidth is lower than the US’s 1200MHz. That is subject to change and the Deco is firmware upgradable.

Note: TP-Link states: “Deco XE75 is compatible with any other Deco model to form a mesh network. Expand mesh WiFi coverage at any time by adding more decos.

We do not recommend mixing Wi-Fi 5 and 6 Deco devices on a 6E backhaul.

CyberShack’s view – TP-Link Deco XE75 Wi-Fi 6E AXE5400 Mesh at the value end of the scale

We only tested the Netgear Nighthawk RAXE500 AX11000 router, which costs more than the Deco 3-pack. It’s not fair to compare AX11000 to AX5400. It’s also not fair to compare the Orbi quad-band RBKE963 router, which costs $2799 for a 3-pack.

The good thing about the TP-Link Deco XE75 Wi-Fi 6E is that you get decent throughput that matches at least NBN 100/20 speeds from the router and its satellites. If you have line of sight, use Wi-Fi 6E backhaul; otherwise ethernet cable is best. This is our standard recommendation for any mesh system.

And if Wi-Fi 6E isn’t part of your foreseeable future, check out TP-Link’s Deco Wi-Fi 6 range.


We have yet to review a Wi-Fi 6E router as we have little to compare it to.

We are happy to say that other Deco XE75 Wi-Fi 6E Tri-Band Mesh for medium-sized households with access speeds of up to NBN 100/20Mbps have no disadvantages.


Extremely easy to set up

Affordable with a 3 year warranty

Reliable and constant speeds

Either Wi-Fi 6E or Ethernet backhaul or daisy chain etc


No signal strength meter for satellite connections

Very basic app functionality

Use Ethernet if you plan to place satellites more than 7-10m away from the router

Only one SSID for 2.4/5 GHz (a separate one for 6 GHz)

Do not mix it with older Deco satellites
