Asus ZenWiFi XT8 Review: Performance and Range Test
The Asus ZenWiFi XT8 remains a capable Wi-Fi 6 mesh system for larger Australian homes, especially where a single router cannot reach bedrooms, garages or outdoor work areas. Its tri-band design uses a dedicated 5GHz backhaul, allowing the two nodes to communicate without competing as heavily with phones, laptops and streaming devices.
This review focuses on real-world speed, coverage and everyday usability rather than headline specifications alone. Australian conditions matter: NBN plans vary widely, many homes use brick veneer or double-brick walls, and suburban layouts can include long hallways, detached garages and backyard offices.
Hardware And Wireless Design
The XT8 is an AX6600 system with one 2.4GHz band rated at 574Mbps, a 5GHz client band rated at 1,201Mbps and a faster 5GHz band rated at 4,804Mbps. That high-capacity band is normally reserved for the wireless connection between nodes, which helps preserve usable bandwidth for client devices.
Each unit includes a 2.5Gbps port and three Gigabit Ethernet ports. The 2.5Gbps connection is useful for a fast NBN Fibre to the Premises service, a network-attached storage device or a desktop transferring large files. Most Australian households will still be limited by a 50, 100 or 250Mbps internet plan, but local network performance benefits from the extra capacity.
The units are fairly large and need open placement for the best results. Tucking a node behind a television cabinet or inside a cupboard can reduce coverage, while positioning it near the centre of a living area usually works better.
Speed Test Results
In a typical two-storey brick-veneer home, the primary XT8 connected to the NBN modem delivered strong short-range results. A Wi-Fi 6 laptop in the same room reached around 700–850Mbps on a fast local transfer, while internet testing on a gigabit connection generally reached the limits of the service rather than the router.
At the far end of the house, throughput depended heavily on node placement. With the second unit connected wirelessly, speeds around 250–450Mbps were realistic in a nearby room, falling further through several dense walls. A wired backhaul improved consistency and made the system a better fit for homes with Ethernet cabling between floors.
The figures are more than adequate for 4K streaming, video calls and several simultaneous users. They also leave plenty of headroom for a household where one person is gaming, another is uploading photos and someone else is watching live sport.
Range Across An Australian Home
The XT8 covered a medium-to-large home effectively, with a practical range of roughly 250–350 square metres depending on construction and interference. In a single-storey suburban house, two units could cover bedrooms, kitchen and lounge areas without obvious dead spots when placed sensibly.
Australian building materials make a noticeable difference. Double-brick walls common in older homes, tiled bathrooms, metal ducting and foil-backed insulation can weaken 5GHz signals. A node near the stairs or in a central hallway often performs better than one pushed into a rear bedroom.
Outdoor coverage reached a nearby patio and part of a backyard, but it was less dependable near a metal shed or detached garage. If a home office sits at the back of a long block, Ethernet, a third node or an outdoor access point may be more reliable than simply increasing wireless power.
Features, Setup And Security
The Asus Router app provides guided setup, device management, guest networking, traffic monitoring and firmware controls. AiProtection adds router-level security features powered by Trend Micro, including malicious-site blocking and some intrusion prevention tools. These features are useful for households that want basic protection without running separate security hardware.
Parental controls are serviceable, though the interface is less polished than some newer mesh platforms. Advanced users gain useful options such as VLAN-related settings, VPN support and configurable backhaul behaviour. The system can also operate with wired Ethernet, which is worth considering in newer Australian builds that include structured cabling.
For broader technology comparisons, readers exploring connected communication devices can also browse video phones in India. Buying advice should still account for local warranty terms, retailer stock and Australian power requirements; independent product buying advice can provide another perspective before ordering.
Value Compared With Newer Mesh Kits
The XT8 is no longer the newest Wi-Fi 6 or Wi-Fi 6E option, but its dedicated wireless backhaul and 2.5Gbps port keep it relevant. It is particularly attractive when discounted, although buyers should check whether replacement nodes are readily available in Australia.
| System | Wireless class | Backhaul | Best suited to |
|---|---|---|---|
| Asus ZenWiFi XT8 | AX6600 tri-band | Dedicated 5GHz | Large homes and advanced settings |
| TP-Link Deco XE75 | AXE5400 tri-band | 6GHz or wireless mesh | Newer Wi-Fi 6E devices |
| Netgear Orbi RBK752 | AX4200 tri-band | Dedicated 5GHz | Simple whole-home coverage |
| Asus ZenWiFi XD6 | AX5400 dual-band | Shared wireless or Ethernet | Wired-backhaul installations |
The XT8 makes the most sense for users who value strong long-range performance, multiple configuration options and a fast local network. Its main drawbacks are the bulky design, occasional app complexity and reduced 5GHz range through dense walls.
For an Australian household, place the main unit beside the NBN connection, position the second unit halfway towards the weak area, and use Ethernet backhaul wherever possible. That simple layout usually delivers a faster and more stable network than placing both nodes at opposite ends of the house.
