TP-Link Deco XE75 Review: The Budget WiFi 6E Mesh That Delivers Pro Performance

The TP-Link Deco XE75 brings WiFi 6E technology to mainstream pricing, delivering AXE5400 tri-band speeds with a dedicated 6GHz backhaul that outperforms many pricier WiFi 6 systems. With support for 200 devices and coverage up to 7,200 sq ft (3-pack), this mesh system solves dead zones without the premium price tag of competing 6E routers.

Summary: The Deco XE75 is TP-Link’s first WiFi 6E mesh system, offering 5400 Mbps combined speeds across three bands (2.4GHz, 5GHz, 6GHz). Its 6GHz dedicated backhaul delivers faster mesh node performance than the flagship Deco X90, making it ideal for gigabit internet connections in medium to large homes. The standard XE75 includes 3 gigabit ports per unit, while the Pro version adds a 2.5Gbps port for multi-gig internet.

What Is the TP-Link Deco XE75?

The Deco XE75 is TP-Link’s entry-level WiFi 6E mesh system that leverages the newly opened 6GHz frequency band to deliver interference-free wireless performance. Unlike older WiFi 6 routers limited to 2.4GHz and 5GHz, the XE75 broadcasts on all three bands simultaneously while dedicating the 6GHz band as a high-speed backhaul between mesh nodes.

This architectural choice dramatically improves multi-room performance. In real-world testing, the XE75 delivered significantly faster speeds through walls compared to TP-Link’s flagship Deco X90 (a WiFi 6 system), despite the X90 having 20% more theoretical backhaul capacity. The cleaner 6GHz signal experiences minimal interference from legacy devices crowding the 2.4GHz and 5GHz bands.

The system is available in 1-pack (2,900 sq ft coverage), 2-pack (5,500 sq ft), and 3-pack (7,200 sq ft) configurations. Each cylindrical unit measures 4.1 × 4.1 × 6.7 inches with a minimalist design that blends into modern interiors.

WiFi 6E: The Game-Changing 6GHz Advantage

How 6GHz Eliminates Network Congestion

WiFi 6E adds a third band in the 6GHz spectrum, effectively doubling available WiFi channels compared to WiFi 6. This new band offers seven additional 160MHz channels (three in EU regions), providing up to 1,200MHz of additional spectrum for 6GHz-capable devices.

The 6GHz band operates as a “greenfield” spectrum; no legacy WiFi 4, WiFi 5, or WiFi 6 devices can connect to it. This eliminates interference from older routers, smart home devices, Bluetooth gadgets, and microwaves that congest the 2.4GHz and 5GHz bands in apartment buildings and dense neighborhoods.

Current testing shows the 6GHz band delivers more stable, consistent speeds because so few consumer devices support it yet. As adoption grows over the next 3-5 years, early adopters of the Deco XE75 will benefit from this uncrowded spectrum.

Dedicated 6GHz Backhaul Explained

The Deco XE75 uses the 6GHz band exclusively for mesh backhaul, the wireless connection between the main router and satellite nodes. Your 2.4GHz and 5GHz devices connect to those bands as usual, but the mesh units communicate over the ultra-fast 6GHz link.

This architecture delivers two key benefits:

1. Faster satellite node performance: Devices connected to a mesh node two rooms away from your modem experience minimal speed loss because data travels over the high-speed 6GHz backhaul rather than competing with client devices on the 5GHz band.
2. Better overall capacity: The 2.4GHz and 5GHz bands remain fully available for client devices since backhaul traffic doesn’t consume their bandwidth.

In practical terms, this means a laptop connected to a Deco node in your bedroom can achieve 600-700 Mbps on a gigabit connection, even with multiple walls between the node and main router.

Performance Testing: Real-World Speed Results

Single Router Performance

At close range (5-10 feet), the Deco XE75 delivered over 800 Mbps on a 1 Gbps internet connection when tested with an iPhone 13. This performance matches other WiFi 6 and 6E routers at short distances, all modern systems saturate gigabit connections effectively.

The real differentiation appears in multi-room mesh scenarios where most users actually need help.

Mesh Node Performance Through Walls

Independent testing revealed the XE75’s standout strength: mesh node performance in challenging conditions.

Test location 1 (2 walls from main unit):
The Deco XE75 significantly outperformed the more expensive Deco X90 flagship when connected to a satellite node with two walls of separation from the main unit. The 6GHz dedicated backhaul proved more efficient than the X90’s tri-band WiFi 6 configuration despite the X90’s higher theoretical backhaul capacity.

Test location 2 (4 walls total – 2 walls past the mesh node):
Even at extreme distances, two walls beyond the mesh node, totaling four walls from the main router, the XE75 maintained a significant speed advantage over the X90. These results were consistent across multiple test runs, demonstrating the real-world advantage of 6GHz backhaul in typical home construction.

One user reported achieving 920 Mbps via ethernet connection to a mesh node, with wireless speeds around 300-500 Mbps depending on the node location roughly 5x faster than their previous system.

Comparison vs Deco X90 Flagship

The Deco XE75 consistently outperformed TP-Link’s WiFi 6 flagship (Deco X90) in mesh scenarios despite being a lower-tier product. This counterintuitive result stems from the cleaner 6GHz spectrum experiencing less interference and congestion compared to the crowded 5GHz backhaul used by WiFi 6 systems.

However, the X90 retains advantages in wired connectivity with its 2.5Gbps port, compared to the standard XE75’s gigabit-only ethernet. For homes with wired backhaul capability, the XE75 Pro (with its 2.5Gbps port) represents the best value.

A robust mesh system like the Deco XE75 ensures that all your smart office devices, from your laptop to wireless printers like the Epson L8050, maintain a stable, high-speed connection.

Deco XE75 vs XE75 Pro: Key Differences

Port Configuration Comparison

The primary distinction between these models is ethernet connectivity:

Deco XE75:

• 3× Gigabit ethernet ports per unit
• All ports support auto-sensing (WAN/LAN)
• Maximum wired speed: 1 Gbps
• Price: ~$299.99 for 2-pack

Deco XE75 Pro:

• 1× 2.5 Gigabit ethernet port + 2× Gigabit ports per unit
• All ports support auto-sensing (WAN/LAN)
• Maximum wired speed: 2.5 Gbps
• Price: ~$399.99 for 2-pack

Both models share identical wireless specifications: AXE5400 speed rating, Broadcom 1.7GHz processor, 512MB RAM, and 200-device capacity. The Pro’s 2.5Gbps port becomes relevant only if you have internet service faster than 1 Gbps or use NAS drives and local file servers.

Which Model Should You Buy?

Choose the standard Deco XE75 if:

• Your internet plan is 1 Gbps or slower
• You primarily use WiFi rather than wired connections
• You want the most cost-effective WiFi 6E solution

Choose the Deco XE75 Pro if:

• You have multi-gig internet (1.5 Gbps or faster)
• You frequently transfer large files between wired devices
• You use a wired backhaul setup and want maximum inter-node speed
• You’re future-proofing for faster internet plans

For most households with gigabit or slower internet, the standard XE75 delivers identical wireless performance at better value. The Pro’s extra $100 buys one faster port useful for power users but unnecessary for typical streaming, gaming, and browsing.

Coverage and Device Capacity

The Deco XE75 system scales coverage based on pack size:

• 2-pack: 3-5 bedroom homes (5,500 sq ft)
• 3-pack: 4-7+ bedroom homes (7,200 sq ft)

These coverage estimates assume typical residential construction with drywall and wood framing. Homes with brick, concrete, or multiple floors may require additional units or strategic node placement.

Each Deco unit supports up to 200 connected devices more than sufficient for smart home ecosystems with dozens of IoT devices, streaming devices, laptops, phones, and tablets. The system uses OFDMA (Orthogonal Frequency-Division Multiple Access) technology to communicate with multiple devices simultaneously, reducing latency in congested networks.

The XE75’s four internal high-gain antennas and beamforming technology focus signals toward connected devices rather than broadcasting omnidirectionally. This targeted approach extends effective range and improves performance at range boundaries.

The Deco app (iOS/Android) handles setup through a guided 3-step process:

1. Physical connection (2 minutes):

• Power off your modem
• Connect one Deco unit to the modem via ethernet cable
• Power on both modem and Deco unit
• Wait for the Deco LED to pulse blue

2. App setup (3-5 minutes):

• Download the Deco app and create/log into your TP-Link ID
• The app auto-detects your Deco model
• Follow prompts to name your network and set a password
• Configure location for the main unit (living room, office, etc.)

3. Adding mesh nodes (2 minutes each):

• Plug in additional Deco units in other rooms
• The app automatically detects and adds each unit
• Assign location names to each node for easy management

Total setup time: 10-15 minutes for a 3-pack system. The app provides video tutorials for each step, making it accessible even for non-technical users.

Wired Backhaul Setup Tips

For homes with existing ethernet wiring, wired backhaul offers maximum performance and reserves the 6GHz band for WiFi 6E clients:

1. Connect your main Deco to the modem, then connect one ethernet port to your network switch
2. Connect satellite Decos to the same switch via wall jacks
3. The system auto-detects wired connections and prioritizes them over wireless backhaul

One user successfully configured this topology: Modem → Deco1 → Managed Switch → Wall Jacks → Additional Deco units. The system automatically recognized the wired backhaul without manual configuration.

If you have wired backhaul capability, the XE75 Pro’s 2.5Gbps port maximizes inter-node transfer speeds for 4K/8K streaming and large file transfers.

HomeShield Security and Parental Controls

The Deco XE75 includes TP-Link’s HomeShield security suite with a free basic tier and optional Pro subscription:

HomeShield Basic (included free):
