ASUS PCE-AX58BT Review by TechCyn

The ASUS PCE-AX58BT is an AX3000 Wi-Fi 6 adapter from ASUS that features the next generation of wireless standard, 802.11ax certified by Wi-Fi Alliance. The AX58BT was engineered for smoother wireless experience by increasing the wireless throughput. The AX58BT offers ultrafast wireless throughput up to 3Gbps thanks to its 160MHz capability along with OFDMA and MU-MIMO technology. Claimed by its manufacturer, the adapter capable to handle the wireless throughput even in the busiest environment. Adding further, the AX58BT features Bluetooth 5.0 just like its predecessor for a faster data transmission through Wi-Fi 6 technology.

The PCE-AX58BT bundles together with a unit of the adapter itself, a unit of antenna base, a pair of dual-band antennas, a unit of low-profile bracket (for small PC form factor), a motherboard USB cable, a quick start guide and a warranty card.

The AX58BT’s PCE plate gives two-antenna ports to be used to extend the wireless receiver by plugging in the cables. The unit has a high quality ASUS crafted heatsink to ease the heat dissipation. Powering the AX58BT up, is an Intel Wi-Fi 6 AX200 wireless card. The unit features 2×2 MU-MIMO Tx/Rx stream with Bluetooth 5.0.

The design of AX58BT differs compared to its predecessor. With an elongated dual detachable antenna, it gives more option to obtain more wireless throughput and a stable wireless connection. The data transfer rate in between Wi-Fi 6 router and client is 2.7 times faster compared to Wi-Fi 5 router and client. The unit combines both OFDMA and MU-MIMO technologies as standard. The freestanding transceiver base is magnetized to allow the stand to be placed at the optimum location over your PC casing and acts as a safety measure to avoid the stand from falling off.


The unit comes with a decent specification according to its manufacturer.

Chipset Solution AX200
Frequency Band Dual Band, 2.4GHz and 5GHz
Bus Type PCI Express x1 interface
Bluetooth Standard Bluetooth 5.0
Data Rate (2.4GHz) 801.11n up to 300Mbps
802.11ax up to 574Mbps (40MHz, 1024QAM, 2.4G)
Data Rate (5GHz) 802.11ac up to 1733Mbps (160MHz)
802.11ax up to 2402Mbps (160MHz, 5G)
Antenna Dual Band External Antenna base x1

According to ASUS, the PCE-AX58BT only supports Windows 10 with 64-bit architecture, while Linux users can enjoy installing the unit both on 32 and 64-bit architecture currently. Do note that, if you’re using Windows 7 or Windows 8.1, you might find incompatibility issues with it.


ASUS PCE-AX58BT Installed by TechCyn

The PCE-AX58BT requires PCI-Express x1 slot to be installed. If you’re using a customized casing with tempered glass installed in, you may have to opt for a better motherboard USB cable that fits your peripherals inside.

ASUS AX58BT driver installation by TechCyn

After setting up the hardware, now the comes the role of installing the recommended software. The interface of the driver rather appears to be like in the earlier days of installing softwares in Windows XP. Further, the driver allows you to install either one of the driver, i.e. WLAN card or Bluetooth. For the purpose of this review, I’ve used Windows 10 64-bit’s driver and install the WLAN adapter.

User Experience

I’ve used both RT-AX56U, a Wi-Fi 6 router and RT-AC68U that act as a standard Wi-Fi 5 wireless router. The result obtained from Wi-Fi 6 router is only focused mainly over 5GHz wireless band.

I’ve used a Wi-Fi 5 router to actually show an example of the maximum wireless throughput achievable when using a typical 802.11ac router. This is to ensure that, you can get a clear picture of the speed you can expect with your current internet connection through wireless connectivity.

I’ve used a standard distance in between placing the AX58BT (PC) and the router located in an enclosed server rack. The test conducted during peak hours to actually get the solid result of the standard speed you should be getting if using your desktop at the night. Based on the test above, I can easily achieve over 200Mbps via 2.4GHz with 40MHz enabled, and 590Mbps via 5GHz with 80MHz enabled. Getting 200Mbps over 2.4GHz considered good already.

Next, I’ve tested the 5GHz capabilities of the Wi-Fi 6 router paired with a compatible Wi-Fi 6 client like AX58BT to actually experience, the true wireless potential of this newer wireless technology. I’ve also enabled the 160MHz channel width to allow maximum utilization of data transmission to actually take place.

Based on the result above, I truly can achieve the speed I wished for. Using 800Mbps of fibre connection, I tend to get such speeds through a wired connection, and when it comes to wireless connection, it is really hard to obtain such speed. The PCE-AX58BT can definitely support speeds for more than 1Gbps solid.


ASUS AX58BT conclusion by TechCyn

Speaking of my experience using wireless previously, I don’t really have a good experience with it. This is one of the reasons why I opt for an ethernet backhaul instead due to better stability and lesser interference. However, I may have to change my perception here by completing the review of AX58BT. To be honest, the AX58BT did a good job by providing a good wireless experience. Thanks to being certified Wi-Fi 6 by Wi-Fi Alliance, the AX58BT suitable to be used with Wi-Fi 6 routers such as the GT-AX11000, RT-AX88U or RT-AX56U. With its Bluetooth generation, a faster data transmission speed is now possible. With that being said, I end my review here by saying, the PCE-AX58BT is a good Wi-Fi 6 client, with Linux support with downside of not supporting 32-bit architecture of Windows 10 and Mac OS.
