The ASUS RP-BE58 is the direct upgrade to the RP-AX58U, which came out a few years ago. The two share the same shape and size. On the inside, though, it’s a more robust version, thanks to Wi-Fi 7 support and the versatile operation roles as part of the AiMesh ecosystem.
Unfortunately, it retains the dated Gigabit port, which hinders its performance when used as the device’s uplink.
Here’s the bottom line: If you already have a Wi-Fi 7 ASUS router with modest broadband, the RP-BE58 is an excellent choice to extend coverage to that far corner, and it’s worth its $99 price tag. On the other hand, if you need faster-than-Gigabit bandwidth, though, pick another option with a Multi-Gig port instead.
Pros
Affordable with dual-band Wi-Fi 7
Reliable performance for sub-Gigabit bandwidth needs
Versatile operation modes
Convenient design, responsive web user interface with optional mobile app
Cons
Uplink bandwidth is limited to a Gigabit
2×2 Wi-Fi specs with modest real-world rates
Relatively bulky with no passthrough socket
ASUS RP-BE58: A modest dual-band Wi-Fi 7 AiMesh-ready coverage extender
Out of the box, the ASUS RP-BE58 is the same as the RP-AX58 (as well as the RP-AX56). It’s a relatively compact device that you can plug directly into a wall socket via its standard two-prong connector.
This snap-on design is convenient but can be problematic, since finding an available wall outlet at the perfect location for the intended Wi-Fi coverage is a matter of luck. Additionally, while the range extender is not huge, it’s large enough to block an adjacent socket, making its lack of a pass-through socket problematic when used in a place with a single wall outlet.
On the inside, it features entry-level 2×2 Wi-Fi 7, with the combined theoretical bandwdith of the 2.4GHz and 5GHz bands being 3600 Mbps—the real-world value, which fluctuates by nature, is always much lower than that.
On the underside, it has a Gigabit port to host a wired client in the mesh or extender mode, or to serve as the uplink in access point mode.
And this Gigabit port is the RP-BE58’s biggest shortcoming—it’s the first Wi-Fi 7 access point I’ve run into that doesn’t have a 2.5Gbps or faster uplink port. When used as the uplink (backhaul), it limits the RP-BE58’s bandwidth to below 1000 Mbps (Gigabit after overhead), regardless of its Wi-Fi rates.
Uplink in a nutshell
When you use multiple Wi-Fi access points—in a mesh Wi-Fi system or a combination of a Wi-Fi router and an extender—there are two types of connectivity: fronthaul and backhaul.
Fronthaul (or downlink) is the Wi-Fi signals broadcast outward to clients or to local area network (LAN) ports for wired devices. It’s what we generally expect from a Wi-Fi broadcaster.
Backhaul (a.k.a. backbone) or uplink, on the other hand, is the link between a Wi-Fi satellite unit and the network’s primary router, or between satellite units.
This link works behind the scenes to keep the hardware units together as a system. It also determines the ceiling bandwidth (and speed) of all devices connected to the particular Wi-Fi satellite unit.
- Hardware of Wi-Fi 6e, Wi-Fi 6, or Wi-Fi 5 standards uses one or more of its bands (2.4GHz, 5GHz, or 6GHz) for the uplink. In this case:
- When a Wi-Fi band handles backhaul and fronthaul simultaneously, only half its bandwidth is available to either end.
- When a Wi-Fi band is used solely for backhauling, often available in tri-band hardware, the link is called a dedicated backhaul.
- In specific cases, Wi-Fi 7 satellite units can combine multiple bands into a single powerful backhaul link thanks to the MLO feature.
For the best performance and reliability, network cables are recommended for uplink or wired backhaul, which is an advantage of mesh Wi-Fi hardware with network ports. In this case, a Wi-Fi satellite unit can use its entire Wi-Fi bandwidth for the fronthaul.
Still, using this port as the uplink is the best way to use the RP-BE58. In a fully wireless setup, only half of its modest Wi-Fi bandwidth is available to clients.
The table below shows the hardware specs of the range extender, compared to those of the previous model, the RP-AX58.

A familiar AiMesh hardware
The ASUS RP-BE58 shares the same firmware and, therefore, has the same setup process and feature set as the rest of the ASUS extenders/routers. It’s straightforward to set up.
All you have to do is plug it into a power socket and connect a device to its default open Wi-Fi network (or its network port). Now you can access its web user interface by navigating a browser to its default IP address (192.168.50.1) or router.asus.com, and the rest is self-explanatory.
You’ll be greeted by a quick wizard to create an admin password and choose its operating mode: standard extender, access point, or media bridge. Additionally, you can use it as an AiMesh node; in that case, follow this detailed guide.
In my case, it took me less than 10 minutes to get it up and running, using any of the operation modes above.
ASUS RP-BE58’s performance: Reliable with modest sub-Gigabit real-world rate
As mentioned, with a Gigabit uplink port, the ASUS RP-BE58 can’t reach the Gigabit barrier when using a wired uplink—either a standard access point or an AiMesh node via a wired bakchaul. But even in the mesh mode, its performance proved modest when coupled with the similarly spec’d RT-BE58U as the primary router.
The good news is that the extender proved reliable during my weeks-long trial in all its operating modes.
In terms of coverage, you can expect the ASUS RP-BE58 to blanket 1500 ft2 (139 m2) of a residential area when placed at the center and used with wired backhaul. When used as a wireless extender or AiMesh node, the extended coverage depends on how you arrange the hardware.
In any case, Wi-Fi coverage is tricky, and your mileage will vary.
Other than that, the RP-BE58 remained relatively cool during operation. In fact, it became just slightly warm to the touch.
Conclusion
The ASUS RP-BE58 BE3600 Dual-Band Wi-Fi 7 Range Extender could have been much better if it had a 2.5Gbps port instead of a Gigabit port. Still, as is, it has enough to justify the $99 price point. Consider it if you have a modest home network and need to extend the coverage to a far corner. In any case, it’ll work best as an AiMesh node of a dual-band ASUS Wi-Fi 7 router like one of those in the best list below.
