Verdict

The ASUS RP-AC55 is a dual-band 802.11ac (Wi-Fi 5) range extender offering combined speeds of up to 1200 Mbps, with 867 Mbps on the 5 GHz band and 300 Mbps on the 2.4 GHz band. It features two external high-gain antennas, a built-in Gigabit Ethernet port for high-speed wired connections, and positioning LED indicators to help users identify the optimal installation spot between the router and dead zones. Main advantages include its 3-in-1 versatility—operating as a repeater, access point, or media bridge—and support for AiMesh technology to create a seamless mesh network with compatible ASUS routers. However, some users have reported potential connection stability issues in certain environments and noted that its 5 GHz band lacks support for higher channels (149 and above).

What customers like about ASUS RP-AC55?

Simple setup process via the WPS button or the dedicated ASUS Extender mobile app
Effective at eliminating dead zones and significantly improving signal strength in multi-room or multi-story homes
Versatile 3-in-1 functionality, supporting Repeater, Access Point (AP), and Media Bridge modes
Handy LED signal indicators assist users in finding the optimal physical placement relative to the router
Compact and portable design that fits easily into standard wall outlets

What customers dislike about ASUS RP-AC55?

Reports of instability, including frequent connection drops or the device losing its configuration with the router
Some users find the initial setup temperamental or cumbersome, occasionally requiring multiple attempts or firmare updates
May experience overheating issues, leading to performance degradation or total connection failure
Bulky design can sometimes block adjacent wall outlets or become loose and fall out of the socket
When not used in AiMesh mode, it may create a separate SSID (adding '_rpt'), which can cause a slight stutter during device roaming

Summary of the review

ASUS RP-AC55 AC1200 Range Extender Review

The ASUS RP-AC55 is an affordable AC1200 wireless range extender that features a compact white design with two non-removable external antennas and helpful LED signal strength indicators. It is highly versatile, offering multiple operation modes including standard Repeater mode, Access Point mode, and Media Bridge mode, which allows wired devices like a PS4 to connect to Wi-Fi via its single Gigabit Ethernet LAN port. Setting up the device is straightforward using the well-designed Asus Repeater app, and it maintains compatibility with routers from any brand while also supporting Asus AiMesh configurations. The performance evaluation highlights several pros, notably its strong network stability, budget-friendly price point, and a useful LED system that alerts users if the extender is placed too close or too far from the main router. However, the review exposes notable cons, such as a major limitation where the 5GHz band does not support higher Wi-Fi channels (channel 149 and above), restricting its backhaul connection strictly to lower U-NII-I channels like 36 to 48. Additionally, users must manually force their main routers to these lower channels to avoid firmware...

Summary of the review

ASUS RP-AC55 Repeater Review - Techtest

The ASUS RP-AC55 is a mid-range Wi-Fi repeater priced at around €55 that features a compact, white design with a diamond texture, two antennas, a physical power switch, and a useful Gigabit LAN port for connecting older wired devices. Setting up the device is highly user-friendly via an unencrypted initial Wi-Fi network and a web-based interface (accessible via 192.168.1.1) that supports Repeater, Access Point, and Media Bridge modes. It advertises theoretical speeds of up to 300 Mbps on the 2.4 GHz band and 867 Mbps on the 5 GHz band while operating with a low power draw between 2.6W and 3.3W. In performance tests paired with an AVM FRITZ!Box 7590, the repeater delivered strong, stable, and highly usable speeds over realistic distances, comfortably handling 4K video streaming on the 5 GHz band. The primary pros include its stable long-range connection quality, an unobtrusive aesthetic, a dedicated Gigabit Ethernet port, and highly efficient power consumption. On the downside, the cons include underwhelming 2.4 GHz band performance that surprisingly lagged behind its cheaper sibling (the RP-AC51), and a basic software interface that...
