One-Minute Review of the Asus RP-AX58

Specifications

  • Wi-Fi Standard: Wi-Fi 6
  • Maximum Speed: 3.0Gbps
  • Ports: 1x Gigabit Ethernet
  • Antennae: 2 internal
  • Dimensions: 150 x 72 x 87mm

Overview

The Asus RP-AX58 is a straightforward dual-band Wi-Fi 6 range extender. Its modest 3.0Gbps speed is ample for streaming and gaming, even if it doesn't match the latest Wi-Fi 7 devices. Its primary role is extending Wi-Fi coverage into areas like upstairs bedrooms or dead zones, making it a cost-effective solution for basic home networking needs.

Price & Availability

| Price | Location | Availability | |--------|-----------|----------------| | $79.99 / £64.99 / AU $103.62 | US, UK, Australia | Available now |

The RP-AX58 is one of the most budget-friendly range extenders on the market, significantly cheaper than Asus’ Wi-Fi 7 models and competitors like TP-Link’s BE3600. As Wi-Fi 6 is older technology, discounts are common online, making this a smart choice for those seeking affordability.

Design and Build

Range extender plugged into mains socket
The RP-AX58 features a sleek, compact design similar to Asus’s Wi-Fi 7 models, measuring just 150mm high, 72mm wide, and 87mm deep. Its plug-in design allows it to fit into any standard power socket, making placement flexible around your home or office.
A Gigabit Ethernet port on the side allows wired connections if needed.

Features and Compatibility

Wi-Fi router and devices
Supporting Asus AiMesh technology, this extender can integrate into a mesh network with Asus routers or mesh systems, enhancing coverage. It operates on both the 2.4GHz and 5.0GHz bands, providing stable connectivity for most devices.
However, the Asus app for setup may feel clumsy, with confusing instructions and UI quirks. The app prompts for a "default password" that isn't initially needed, but afterward allows you to set network details.

Performance

| Benchmark | Result | |-------------|---------| | Wi-Fi Speed (2.4GHz) | Up to 120Mbps within 30ft through 3 walls | | Wi-Fi Speed (5.0GHz) | Up to 150Mbps within 30ft through 3 walls | | Steam download | 120Mbps on 2.4GHz, 150Mbps on 5.0GHz |

In real-world tests, it effectively eliminated dead zones, delivering reliable speeds suitable for browsing, streaming, and downloads. Its performance is comparable to more expensive extenders, though it doesn’t match the speed of Wi-Fi 7 devices.

Should You Buy the Asus RP-AX58?

| Rating | Summary | |---------|----------| | Value | 4/5 - Excellent affordability for a basic extender | | Design | 4/5 - Compact and unobtrusive | | Features | 3/5 - Simple but effective for boosting coverage | | Performance | 3/5 - Adequate for most home tasks | | Final Score | 3.5/5 |

Ideal for:

  • Extending Wi-Fi into a specific dead zone
  • Budget-conscious users needing reliable coverage
  • Those with older devices supporting Wi-Fi 6

Not suitable for:

  • Early adopters with Wi-Fi 7 devices
  • Larger homes requiring comprehensive mesh systems

Alternatives to Consider

| Device | Price | Wi-Fi | Max Speed | Antennae | Ethernet Ports | |---------|---------|--------|-----------|-----------|----------------| | Asus RP-BE58 | $99.99 | Wi-Fi 6 | 3.6Gbps | 2 internal | 1x Gigabit | | TP-Link AXE5400 | $139.99 | Wi-Fi 6E | 5.4Gbps | 4 external | 1x Gigabit |

The Asus RP-BE58 provides Wi-Fi 7 capabilities and slightly higher speeds but at a higher price point. For extensive coverage, a mesh Wi-Fi system might be more suitable.
