If you’re searching for a new Wi-Fi 6E mesh system, you’ve likely come across the TP-Link AXE5400 (Deco XE75) and the Asus ZenWiFi XT8. Both are popular choices for users who want faster speeds, better coverage, and a reliable connection for many devices. But which one is really better for your home or office? Making the right decision depends on understanding how these two systems compare in real use — not just on paper.
Let’s take a close look at both, focusing on real-world performance, features, and value. By the end, you’ll know exactly which mesh system fits your needs best.
Design And Hardware
The first thing you’ll notice is the design. The TP-Link AXE5400 Deco XE75 comes in a simple cylindrical shape. Its minimalist look helps it blend into most rooms, and it’s smaller than many competitors. The Asus ZenWiFi XT8, on the other hand, uses a more rectangular, vertical design with subtle lines and a metallic finish. Some people find the Asus a bit more “techy” looking, while the TP-Link is more neutral.
Both systems are solidly built. The Deco XE75 is lightweight but sturdy, with rubber feet to prevent slipping. The ZenWiFi XT8 feels heavier, possibly due to its larger heat sinks and more advanced internal hardware. This can mean better long-term reliability, especially in warmer environments.
When it comes to ports, the ZenWiFi XT8 has a clear advantage. Each unit has three Gigabit LAN ports and a 2. 5Gbps WAN port. This is excellent if you have fast wired connections or want to connect network storage directly.
The Deco XE75 has two Gigabit Ethernet ports per unit, but no multi-gig port. For most users, this is enough, but if you want the fastest wired speeds, Asus is ahead.
Wireless Technology And Bands
One of the main reasons people upgrade to new mesh systems is to get the latest Wi-Fi technology. The Deco XE75 supports Wi-Fi 6E, which adds a new 6GHz band to the usual 2.4GHz and 5GHz bands. This means less interference and higher speeds, especially for new phones and laptops that support Wi-Fi 6E.
The Asus ZenWiFi XT8 supports Wi-Fi 6 (not 6E), so it only offers 2.4GHz and 5GHz bands. However, it uses a dedicated 5GHz backhaul band for communication between nodes. This means devices won’t have to share bandwidth with the system’s internal communications, which helps keep speeds high even as you add more devices.
If you have a lot of new gadgets that support Wi-Fi 6E, the Deco XE75 will give you a real speed boost. But if you mostly use older devices, the ZenWiFi XT8’s strong backhaul and mature Wi-Fi 6 support may be more valuable.
Speed And Performance
Let’s talk about real numbers. The TP-Link Deco XE75 is rated for up to 5,400 Mbps (hence the “AXE5400” name), split across its three bands:
- 2.4GHz: Up to 574 Mbps
- 5GHz: Up to 2402 Mbps
- 6GHz: Up to 2402 Mbps
The Asus ZenWiFi XT8 is rated for up to 6,600 Mbps:
- 2.4GHz: Up to 574 Mbps
- 5GHz-1: Up to 1201 Mbps
- 5GHz-2 (backhaul): Up to 4804 Mbps
On paper, Asus wins on total bandwidth. But real-world speeds depend on how devices connect and what bands they use. In most homes, you’ll see:
- Deco XE75: 600-900 Mbps on Wi-Fi 6E devices at close range, 400-600 Mbps on Wi-Fi 6/5 devices
- ZenWiFi XT8: 500-800 Mbps on Wi-Fi 6 devices, 300-500 Mbps on Wi-Fi 5 devices
If you have a fast internet plan (1 Gbps or more), both systems can deliver high speeds if your devices support the latest standards. The main difference: the Deco XE75’s 6GHz band can get less crowded, but only newer devices can use it.
Mesh Coverage And Scalability
Both systems are designed to cover large homes. The Deco XE75 (2-pack) claims to cover up to 5,500 sq. ft., while the ZenWiFi XT8 (2-pack) is rated for 5,500-5,700 sq. ft. These numbers are based on ideal conditions — open spaces, few walls, and minimal interference.
In real homes with walls and furniture, coverage is often lower. Still, both systems can cover most medium to large homes with two units. You can add more units to expand coverage, but mixing brands is not recommended.
A unique feature of the ZenWiFi XT8 is its dedicated backhaul. This makes it especially effective in larger homes or when nodes are far apart. The Deco XE75 uses its 6GHz band as backhaul if possible, but this only works if the nodes are close and there’s minimal obstruction. If you need to place units far apart, the Asus may maintain better speeds between them.
Setup And Ease Of Use
Setting up a mesh system can be intimidating, but both brands have worked to make it simple.
- TP-Link Deco XE75: The setup is managed via the Deco app, which guides you step by step. Most users report that the process takes less than 15 minutes. The app is clear, with simple language and easy-to-follow visuals. You can add more Deco units later with just a few taps.
- Asus ZenWiFi XT8: Setup can be done via the Asus Router app or a web browser. The app is more detailed, with more advanced options for users who want to tweak settings. The initial setup wizard is straightforward for beginners, but some screens use technical terms.
For most users, the Deco XE75 is slightly easier to set up, but the ZenWiFi XT8 offers more options for advanced users.
Software Features And Controls

If you want the best free security, Asus is the clear winner.
Smart Home Compatibility
Both mesh systems work with most smart home devices, but there are some differences:
- TP-Link Deco XE75: Supports Alexa voice commands. You can pause Wi-Fi, check device status, or set up guest networks with your voice. Works well with TP-Link’s own smart plugs and bulbs.
- Asus ZenWiFi XT8: Works with Alexa but supports fewer direct voice commands. It does, however, offer better compatibility with advanced smart home features like VLANs and device isolation, which can help keep your smart home secure.
If you have a lot of smart devices, both will work, but Asus gives you more control over how they connect and interact.
Price And Value
Price changes often, but generally:
- TP-Link Deco XE75 (2-pack): $250–$300
- Asus ZenWiFi XT8 (2-pack): $350–$400
The Deco XE75 is more affordable, especially for Wi-Fi 6E support. The ZenWiFi XT8 is pricier, but you’re paying for advanced features, a multi-gig port, and lifetime security.
If price is your main concern, the Deco XE75 is hard to beat. If you want every possible feature and don’t mind spending more, the ZenWiFi XT8 is worth considering.
Real-world Usage: Speed, Stability, And Roaming
How do these systems perform in daily life? Here’s what users and testers report:
- Deco XE75: Fast, stable speeds in open spaces. The 6GHz band is great if your devices support it. Some users report drops in speed if nodes are too far apart or separated by thick walls, as 6GHz struggles with obstacles. Roaming between rooms is smooth, with minimal drops.
- ZenWiFi XT8: Very consistent speeds, even with nodes far apart, thanks to the dedicated 5GHz backhaul. Slightly better at maintaining connections through walls and floors. Roaming is seamless, with devices quickly switching to the best node.
For challenging layouts (many walls, large houses), the ZenWiFi XT8 may offer more reliable whole-home coverage. For open layouts with newer devices, the Deco XE75 will likely feel faster.
Two Key Insights Beginners Miss
- Device Compatibility Limits: Only the newest phones, laptops, and tablets can use the 6GHz band on the Deco XE75. If your devices are a few years old, you won’t benefit from this new band. Beginners often expect a big speed jump, but it depends on what you connect.
- Backhaul Matters: The way mesh nodes connect to each other (backhaul) is just as important as their connection to your devices. The ZenWiFi XT8’s dedicated backhaul keeps speeds high even as you add more devices or spread nodes further apart. Many users focus only on headline speeds, not how the mesh connects internally.
