To get a better idea of the performance offered by ASUS GS-AX5400, we compared it with ASUS RT-AX82U - another AX5400 Wi-Fi 6 router with identical hardware, similar features, price, and marketing positioning. We also compared it to an older Wi-Fi 5 gaming router with the same 5400 Mbps bandwidth TP-Link Archer C5400X, just to get a perspective of whether there are any meaningful differences when switching from a Wi-Fi 5 router to a Wi-Fi 6 one.

We first analyzed the 2.4 GHz band using the Wi-Fi 4 standard and measured the signal strength with NetSpot. The signal strength offered by ASUS GS-AX5400 was pretty good in all the rooms from our test apartment.

We used SpeedTest to measure the internet connection speed when connected to the 2.4 GHz band on Wi-Fi 4. The download speed offered by ASUS GS-AX5400 was pretty good in all the rooms of our apartment. In troublesome places like the Kitchen and other rooms where many routers struggle, ASUS GS-AX5400 is the speed champion of this comparison.

We then used the PassMark Performance test to transfer data between two computers connected to the network using Wi-Fi 5. ASUS GS-AX5400 outmatched the other routers in only one room. While it performed well in all the others, it was not the speed champion of this comparison.

We remained on the 5GHz wireless band, but we switched to using the Wi-Fi 6 standard. Because the TP-Link Archer C5400X is an older Wi-Fi 5 router, it doesn’t get featured in the comparisons that follow.

We first used SpeedTest to see how fast the internet connection is when using Wi-Fi 6. When measuring the download speed, ASUS GS-AX5400 exchanged blows with ASUS RT-AX82U. There was no clear winner between the two.

When using Wi-Fi 6, ASUS ROG Strix GS-AX5400 is an excellent performer, offering fast network transfers and wide coverage.

Wired network performance

It’s time to evaluate the performance we get on Ethernet network connections. When we reviewed the other routers in this comparison, our internet connection was capped at 1 Gbps for the download speed and 500 Mbps for the upload speed. In the meantime, the cap for the upload speed has increased to 800 Mbps. When using SpeedTest, ASUS GS-AX5400 reached the maximum potential of our internet connection, as you can see below.

Then, we ran a network transfer between two computers, using the PassMark Performance test. ASUS GS-AX5400 got very close to the maximum speed possible of 1 Gbps. Then again, the others did as well.
