Asus Zenwifi XT9

Asus XT8 marked the debut of the ZenWiFi series featuring Wifi 6 technology. However, today, you’ll find the latest addition to the lineup, the Asus ZenWiFi XT9. With its upgraded label from XT8 to XT9, it’s natural to expect that the Asus ZenWiFi XT9 comes packed with even richer features and specs compared to its predecessor.

So, what sets the Asus ZenWiFi XT9 apart from the XT8 series? Let’s explore the key differences between these two ZenWiFi models.

Asus zenwifi xt9 vs xt8

Let’s take a closer look at any potential specs or features differences between the two ZenWiFi series. Refer to Table 1 below for a comprehensive spec comparison.

Physical appearance

Remarkably, both series boast the same casing body, allowing for seamless interchangeability between the two. With identical item dimensions, width, length, and height, the ZenWiFi XT8, XT9, and even the ZenWiFi ET8 share a consistent physical feel and style. Be mindful of these similarities when distinguishing between these three series.


While both ZenWiFi series share similarities in the network segment, there are subtle differences in total bandwidth. So, why did Asus introduce the XT9 when the Asus XT8 was already quite popular? The answer lies in the differences in backhaul methods between nodes.

Both series utilize dedicated backhaul at 5GHz, but the methods applied slightly differ. In the Asus XT8, you have the flexibility to choose between two 5GHz bands for backhaul, offering speeds of either 1200mbps or 4800mbps.

Backhaul options

If you opt for the two-pack model, choosing a dedicated backhaul at 4800Mbps might seem excessive, leaving only 1200Mbps + 600Mbps for connected clients. Alternatively, selecting 1200Mbps as the dedicated backhaul allows the other two bands at 4800Mbps + 600Mbps to cater to connected devices, which is also a good configuration. However, in the case of the three-pack kit, the 1200Mbps backhaul might prove insufficient, particularly with a high client density.

Recognizing this weakness, Asus introduced the ZenWiFi XT9 to address the backhaul method. The XT9 offers improved options, including a 4800Mbps dedicated backhaul, wired backhaul, and an automatic backhaul setting. This automatic backhaul option is also available on the latest Asus ZenWiFi series, such as the Asus ZenWiFi ET8 and Asus ZenWiFi ET12.

With the auto backhaul system, the XT9 provides the most suitable backhaul link under various conditions. In my opinion, the auto option proves to be the best choice when uncertainty exists regarding the system’s bandwidth requirements under different conditions. The best part is that the system handles this automatically.

In summary, the Asus ZenWiFi XT9 represents a significant improvement over the XT8, offering a larger bandwidth and enhanced capability to provide the optimal backhaul solution for varying conditions.

You can see more details from the table below for spec and feature comparison between the two series.

So in a nutshell asus xt9 is one step higher level than asus xt8 with higher bandwidth, automatic backhaul link options, and also a slightly faster processor.

Asus XT9 vs Deco XE75 Pro

Asus xt9 is still based on wifi 6 technology, while the upcoming wifi 7 technology is a short coming years. Between the wifi 6 and the upcoming wifi 7 technology (which also use the same 6ghz band) is wifi 6e which is the enhancement of existing wifi 6.

When it comes to decide which one between asus xt9 wifi 6 and deco xe75 pro wifi 6e to choose to upgrade your home wifi network, what your considerations are for choosing considering that the future is wifi 7?

Let’s see what the differences between asus zenwifi xt9 and the wifi 6e product offered by tplink deco xe75 pro. Table 2 below represents spec comparison between asus xt9 and deco xe75 pro. Tplink deco xe75 pro is one of few models tplink products based on wifi 6e technology including the premium one tplink deco xe200 axe11000 mesh wifi 6e.

Wifi design

Asus xt9 delivers total bandwidth wider than the one offered by deco xe75. However, deco xe75 is wifi 6e system that offers three distinct radio bands with the addition of 6ghz band instead of standard 2.4ghz and 5ghz radio bands in general. The upcoming wifi 7 technology is using the same 6ghz radio band as wifi 6e.

As we discussed above that asus xt9 comes with wider bandwidth than previous model xt8, and the backhaul method is redesigned with the option of auto backhaul by system for best backhaul link available in any different network conditions.

Deco xe75 by default uses @6ghz band as dedicated backhaul link between nodes, however you have few 6ghz connected devices you can opt to change the 6ghz dedicated backhaul as network to allow 6ghz products connect to the network. with asus xt9 you don’t have option to allow 6ghz products to connect to the network.

Honestly speaking, deco xe75 is based on wifi 6e will be better in welcoming the future of wifi 7 products which is also use 6ghz radio band. There will be more devices with 6ghz band to come in the future, so the readiness of your network to support 6ghz band is essential.

More ports

The good thing with asus xt9 is that it comes with more ethernet ports than deco, moreover it also comes with one latest usb 3.2 port to allow you to host usb hard disk storage for network sharing. Usb port can also be used as dual wan when you insert usb cellular modem dongle as failover internet or load balance internet. Deco xe75 doesn’t come with usb port, and the ethernet ports are only three as opposed to four in xt9. When it comes to use the ethernet ports for wired backhaul link between router node and two satellite nodes, both xt9 and xe75 are ready for star backhaul topology without adding separate ethernet switch.
