Asus ZenWifi XT9: One-minute review
The latest addition to the range is the new Asus ZenWifi XT9 which, as the name suggests, is a follow-up to the Asus ZenWifi XT8. In truth, this Wi-Fi router is not a massive upgrade, providing tri-band Wi-Fi 6 with a top speed of 7.8Gbps, compared to 6.6Gbps for the XT8. However, this mesh Wi-Fi system has the same range of features – including free parental controls – and admirable ease of use that makes it a good option for larger homes that need fast, reliable Wi-Fi.
Not content with being one of the world’s leading PC manufacturers – with the Republic Of Gamers brand also under its wing – Asus also makes some pretty impressive networking products. Its XT8 mesh system walked off with our Editor’s Choice a couple of years ago, with the top-of-the-range ZenWifi Pro ET12 bringing the state-of-the-art Wi-Fi 6E technology to the range more recently.
So, does the Asus ZenWifi XT9 maintain the same lofty standards? Read our review of the Wi-Fi 6 router to find out more.

The increased speed of the Asus ZenWifi XT9 does mean that it’s a little more expensive than its predecessor – and we also have to take Asus to task for the slightly misleading information on its web site. The web site shows a picture of a two-piece mesh system, with two identical routers, and states that prices “start at $269.99” (£256.49).
In fact, that’s the price for a single XT9 router on its own, which can work like a conventional router, covering an area of up to 2,850 sq.ft (or homes with up to four bedrooms). The two-piece mesh system that we review here actually costs $499.99 / £459.99 and is suitable for larger homes up to 5,700 sq.ft (for 6+ bedrooms).
That’s quite expensive, but still comparable to rival mesh systems that provide this level of performance, and online prices do seem to vary quite a bit, so it’s worth shopping around before buying. It also means that the older XT8 has now been reduced in price, providing a more affordable alternative that will be more than adequate for most domestic broadband services. The Asus ZenWifi XT8 is still the best option for users in Australia too, as the XT9 hasn’t yet been released in that region.
Asus ZenWifi XT9: Design
- Smart, compact design, in black or white
- App is very easy to use
- Good parental controls, with no subscription
The Asus ZenWifi XT9 may be a bit pricey, but it works hard to earn its keep. Available in black or white, the two XT9 mesh routers have the same slim, upright design as the older XT8, which allows each router to house six internal antennae to boost transmission of the Wi-Fi signal. And, as mentioned, the mesh Wi-Fi system provides tri-band Wi-Fi 6 that uses 2.4GHz and two 5.0GHz frequency bands.
To make the most of that performance, the XT9 has a 2.5 Gigabit Ethernet (WAN) port for high-speed broadband connections, along with three Gigabit Ethernet ports to provide wired connections. There’s even a USB-A 3.2 port that allows you to connect a hard drive or other storage device, which can be shared with other people on your network.
Getting started is a piece of cake. The two XT9 routers are identical, but one of them has a label on the front that says – “I’m the main router, so start with me!”. There’s a QR code that lets you download the Asus Router app for iOS and Android, and a second one that prompts the app to link the two XT9 routers together, checks your Internet connection, and connects your iOS or Android device to the new network.
You do need to create a name (SSID) and password for your new Wi-Fi network, but the app allows you to create a single network that merges the 2.4GHz and 5.0GHz bands for quick and easy set-up. Or you can separate the three bands and set up three networks with their own individual passwords. That will take a little longer, but it’s a useful option if you want to dedicate one of the fast 5.0GHz bands to a device such as a gaming console or PC for maximum performance. For more advanced users, the app also allows you to open up a web browser interface that provides more detailed control over the network settings.
The app provides standard features, such as a guest network and the ability to prioritise applications such as gaming or streaming video for maximum performance. However, we were also pleased to find that it provides good parental controls, including content filters that can block unsuitable material. These filters are free of charge, too – unlike many rival routers that require a monthly subscription fee for parental controls.
Asus ZenWifi XT9: Performance
- Fast Wi-Fi 6 performance, with good range
- 2.5 Gigabit Ethernet for high-speed broadband connections
- 3x Gigabit Ethernet for wired connections

20GB Steam 20GB download – 5.0GHz
Within 5ft, no obstructions: 19MB/s
Within 30ft, three partition walls: 19MB/s
The whole point of mesh systems is that they can provide fast Wi-Fi that covers your entire home.
Our normal router can provide good Wi-Fi performance for computers and other devices that are nearby, reaching 150Mbps on the Ookla speed test, and 19MB/s for Steam downloads. However, our router struggles to reach one office at the back of the building, where the Wi-Fi signal is so unreliable that we rely on PowerLine adaptors to provide a wired connection instead.
With one Asus ZenWifi XT9 connected to our router, and the second located halfway along that corridor, we are able to get smooth, steady speeds of 150Mbps and 19Mb/s for Ookla and Steam once more – even on the slower 2.4GHz band.
