The total maximum theoretical bandwidth is split as follows: 574 Mbps on the 2.4 GHz band and 4804 Mbps on the 5 GHz when using the Wi-Fi 6 standard. However, these speeds are different from what you see in real life, and we recommend reading our measurements from page two of this review.
ASUS TUF-AX5400 is pretty large, and one neat aspect for gamers is the RGB-lit logo on the top cover, which can be customized from the firmware. However, the router is surprisingly lightweight at 1.45 pounds or 660 grams, considering the beefy ventilation system that includes a heatsink.
Notice the RGB-lit TUF logo on the top
Specs-wise, the TUF-AX5400 is a powerful wireless router with exciting features that should please many users, including online gamers.
Setting up the ASUS TUF-AX5400
When turning on Wi-Fi 6, ASUS informs you that some wireless network cards may have connectivity issues with this standard. Therefore, it is a good idea to update the network drivers on all your laptops, computers, and devices before enabling it.
One nice touch is that ASUS checks for firmware updates before finishing the quick setup wizard and encourages you to upgrade before you start using it. We also recommend you install the latest firmware because it fixes bugs that were present in the initial release. Another positive is that you can later set the firmware to auto-update itself during the night, when nobody is using the internet. Therefore, you can always stay up-to-date, with no effort on your part.
It is a good idea to install the latest firmware
Connect your devices to the network and access the firmware for more fine-tuning when the quick setup is finished. This router’s administration interface is easy to use, well organized into logical sections, and available in 25 languages. You control everything you wish, from the RGB lighting to Open NAT, to IPv6, and so on. The features list is impressively long, and both casual and advanced users should be happy with the level of detail they receive.
The firmware for the ASUS TUF-AX5400
We like the fact that TUF-AX5400 has 160 MHz channel width support for Wi-Fi 6, and we recommend that you enable it for improved speed on this standard.

Another helpful feature is that this router comes with AiMesh support, and you can use TUF-AX5400 to create a mesh Wi-Fi network using other ASUS routers.
You can also set up and manage the router from any Android smartphone or iPhone using the ASUS Router app. The app can be used from anywhere on the internet, and it includes plenty of settings that can be configured.
The ASUS Router app works with ASUS TUF-AX5400
To verify the quality of the Wi-Fi broadcast by ASUS TUF-AX5400, we took our laptop and moved it to a room separated by one wall from the router. Then, we made a wireless transfer on it, using a specialized app that measured the average speed and the network transfer variability. On the 2.4 GHz band and the Wi-Fi 4 standard, the average speed was OK but not as fast as what other routers can deliver. Also, the variability of the network transfer was relatively high. From our testing experience, we believe that Wi-Fi 4 is an improvement area for future firmware versions of this router.

Discussion (3)
I think I’ll stay with my ASUS RT-AX86U router. Faster processor, more processor cores, more memory. Stands vertical for better cooling. Mostly same features except Google.
ASUS RT-AX86U is an excellent router. You don’t need to change it.
The RT-AX86U is an amazing router, however here in the UK the AX86U retails at £229, whereas the AX5400 is £119. I’d expect a significant improvement in performance for almost twice the cost.
