Wireless network performance
My test apartment is set up like in the diagram below. I’ve placed the ASUS RT-BE58U in a central position to provide good coverage in an area as large as possible.

The apartment where I tested ASUS RT-BE58U
I evaluated the quality of the wireless network managed by this router through measurements made in three different places:
- The router’s room - I record the maximum speeds when no walls absorb the wireless signal in the room where the router is placed.
- Room 1 - is separated by one wall from the router, so the wireless signal and the Wi-Fi speed I get should be lower here.
- Room 2 - is separated from the router by two walls absorbing the wireless signal. Also, the wall between Room 1 and Room 2 is twice as thick as the one between The router’s room and Room 1. As a result, Room 2 can be a difficult challenge for many routers.
I’ve made all my measurements on an ASUS Zenbook S 16 laptop that can work with Wi-Fi 7 networks. I used Windows 11 version 24H2 and the latest drivers and updates at the time of testing.
To better understand how ASUS RT-BE58U performs, I compared it with three other dual-band Wi-Fi 6 routers that have a relatively similar total maximum bandwidth: TP-Link Archer AX55, ASUS TUF Gaming AX3000 V2, and Xiaomi Mi AIoT Router AX3600. This comparison is relevant because it tells us whether this router can deliver meaningful improvements compared to popular Wi-Fi 6 routers with relatively similar specs. I couldn’t compare the ASUS RT-BE58U with another Wi-Fi 7 router because I haven’t tested any until now. Let’s see how it fared:
How the ASUS RT-BE58U performs on the 2.4 GHz band
I first measured the signal strength using NetSpot when connected to the 2.4 GHz band on the Wi-Fi 7 standard (802.11be). The other routers I used for this comparison were using the Wi-Fi 6 standard. As you can see below, ASUS RT-BE58U delivered slightly lower signal strength in every room in my apartment. However, this doesn’t necessarily mean lower performance.

When using SpeedTest to measure how fast my internet connection works on the 2.4 GHz band, I was pleasantly surprised to see that ASUS RT-BE58U delivered the fastest downloads in all the rooms where I made measurements.

Uploads were significantly faster than on the routers I’ve compared it to, showing that switching to a Wi-Fi 7 router like the ASUS RT-BE58U can be a good choice.

For the next set of measurements, I used the PassMark Performance Test to transfer data between two computers connected to the network. One was the laptop I mentioned earlier, connected over Wi-Fi on the 2.4 GHz band, and the other was a desktop computer connected to the router through an Ethernet cable. As you can see below, the ASUS RT-BE58U delivered fast download speeds in all the rooms.

Uploads were fast, too. I especially liked that the ASUS RT-BE58U performed very well in Room 2, which is separated from the router by two walls that do a great job of absorbing the wireless signal.

My initial testing revealed that the ASUS RT-BE58U performs very well on the 2.4 GHz band, easily outperforming popular Wi-Fi 6 routers. This router and the Wi-Fi 7 standard did a great job in rooms where walls were problematic for Wi-Fi 6 routers, delivering much faster and more reliable downloads and uploads.
How the ASUS RT-BE58U performs on the 5 GHz band
I switched to the 5 GHz band and repeated the same measurements. This time, the signal strength delivered by the ASUS RT-BE58U router on the 5 GHz band was very similar to that of the Wi-Fi 6 routers I’ve included in this comparison. A good starting point! 🙂

Moving on to SpeedTest, the download speeds I measured were consistent. While the ASUS RT-BE58U was not the fastest router in my comparison, it delivered faster downloads in Room 2, which has proved problematic to the other routers.

Uploads were slower, and their speed was underwhelming.

Switching to the PassMark Performance Test revealed that ASUS RT-BE58U can maintain an excellent throughput, with download speeds that are consistently faster than those of similar Wi-Fi 6 routers.

In this test, uploads were fast, too, with ASUS RT-BE58U delivering excellent transfer speeds, which were also quite steady.

When testing the ASUS RT-BE58U on the 5 GHz band, its performance was mixed. In some tests, it was outmatched by Wi-Fi 6 wireless routers with a similar total bandwidth, while in others, it was clearly faster.
Wired network performance & USB port
I also wanted to verify how the ASUS RT-BE58U performs when using Ethernet connections. My internet connection offers a maximum download speed of 1 Gbps and an upload speed of 800 Mbps. When tested with SpeedTest, this router achieved a maximum download speed of 922.69 Mbps, which is similar to that of the routers I compared it to, and an upload speed of 696.94 Mbps, which is slower than I would have liked.

SpeedTest on 1 Gbps Ethernet connections
For the last test, I wanted to measure the speed of the USB 3.2 Gen 1 port that’s found on the back of the ASUS RT-BE58U, which, among other things, allows users to turn their units into a NAS (Network Attached Storage) by connecting a fast SSD to it. I did the same and transferred some data to and from the SSD. The download speeds I achieved were very high: 879.35 Mbps, and the uploads were equally impressive: 644.34 Mbps. In the chart below, you can see how the ASUS RT-BE58U compares with the other routers. Remember that the Xiaomi Mi AIoT Router AX3600 is missing from this chart because it doesn’t have a USB port.

The speeds achieved through the USB port
ASUS RT-BE58U is also a fast router when you’re connecting devices through network cables. However, the upload speed I measured wasn’t as high as the one on other routers I’ve used. Luckily, this aspect wasn’t problematic. While the USB port on this router had some stability issues, it proved to be very fast when it worked.
What is your opinion about the ASUS RT-BE58U?
