The RT-AX55 look classic design compare to previous budget router that we have review RT-AC2600.

ASUS RT-AX55 router is slower in term of wireless bandwidth, because of 2T2R antenna configuration compare to RT-AX2600 4T4R and RT-AX55 lack of  USB port support for Ai Cloud technology. However, the new AX standard make use of “OFDMA” orthogonal frequency-division multiple access to achieve better performance when multiple devices are connected, so there’s less to be gained by spreading the load across.

2.4Ghz 5Ghz USB Support AX support
RT-AX55 574Mbps 1201Mbps No Yes
RT-AC2600 800Mbps 1733Mbps Yes No

On the back you have four vertical antennas together, four Gigabit Ethernet ports along with a Gigabit WAN port, WPS, power and reset buttons.

The wireless standards are supported, including OFDA, MU-MIMO, beamforming, and the latest security standard of WPA3-personal, but lack of support 160Mhz channel. The router is also fully backward compatible to 802.11ac (Wi-Fi 5) and 802.11n (Wi-Fi 4) devices.

Main Menu UI

Once the initial setup is complete, we can get into router Menu for more advance configuration. The router’s features are easily navigated via the left-hand panel.

We installed latest version to ensures that all the latest security updates are applied, along with bug fixes. For our testing, the RT-AX55 was running firmware version 3.0.0.4.386.42350.

Security

The Asus RT-AX55 includes a  number of security features, but it’s runs Ai Protection Classic so you will see lesser feature compare to Ai Protection Pro. Network Protection with Trend Micro can provide anti malware on a network level, for no additional charge. Also, malicious sites are blocked at the router to keep the entire network secure, but lack of Two-Way IPS protection.
[We have been placing this router as our main use to test the Ai Protection for 4 days and see the result below]

Performance/ Benchmark Testing

We tested the Router directly using Speedtest on WAN to Internet directly.

When it comes to wireless bandwidth, the Asus RT-AX55 performed quite well. We test routers in three location a “Living room” location, “Computer room” and also at a “Bedroom” location. The bandwidth test uses Speedtest, Netflix, cloudflare and internal file transfer to benchmark the performance, with a Wi-Fi 6 client. For the latter, we have a laptop ASUS Zenbook UX435EGL with an Intel Wi-Fi 6 AX201 160MHz wireless adapter on latest driver, set to use the widest 80 MHz channel width on the 5 GHz frequency.

House layout & testing details

We will test three difference location using ASUS Zenbook UX435EGL and out internet service provider is M1 – 1Gbps. Please take note that our testing is using “Smartconnect” technology on 5Ghz bandwidth.
