Network transmitter ASUS RP-AX58 — dual-band Wi‑Fi 6 (802.11ax), 2400 Mbps, 1× Gigabit LAN, 2 internal antennas, white

The ASUS RP-AX58 (AX3000) is a dual-band WiFi 6 range extender and AiMesh node that expands wireless coverage and improves network capacity in homes and small offices. It supports IEEE 802.11ax/ac/n/g/b/a standards, offers combined speeds up to 3000 Mbps, and is compatible with most WiFi routers, modems and gateways. The unit includes a gigabit Ethernet port for wired backhaul or wired client connections and features a compact white housing with internal antennas.

Advantages

The RP-AX58 delivers WiFi 6 performance with support for 160 MHz channels (where regionally permitted) to provide faster throughput and higher network capacity compared with WiFi 5 repeaters. It supports ASUS AiMesh to form a whole-home mesh with compatible ASUS routers, and can also operate with nearly any third‑party router in extender or access point modes. A gigabit Ethernet LAN port enables stable wired backhaul or connection of wired devices, and the device’s compact dimensions make placement flexible.

Suitable for

• Extending wireless coverage in apartments and houses (up to approx. 2,200 sq. ft., depending on environment)
• Adding capacity for multiple streaming, gaming and smart home devices
• Creating an AiMesh whole-home WiFi system with other ASUS routers
• Using wired backhaul or connecting a wired client via the gigabit Ethernet port

How to use

Plug the RP-AX58 into a power outlet within range of your existing router and follow the on-screen setup steps in the ASUS extender app or web interface to connect it to your network. Choose extender mode to extend your current WiFi network or Access Point/AiMesh node mode to integrate with an ASUS AiMesh router. For the most stable connection, optionally connect the RP-AX58 to your router with an Ethernet cable to use wired backhaul; this reserves wireless bands for client devices.

Recommendations

Place the extender roughly halfway between your router and the dead zone for optimal coverage, avoid dense obstacles and large metal objects, and update firmware via the ASUS interface to ensure security and best performance. Note that 160 MHz operation and WiFi 6 benefits require region availability and compatible client devices.
