ASUS RT-AX88U Review 2024

Before I begin with a detailed review of the ASUS RT-AX88U, let me tell you how I tested it:

I paired the Netgear CM1000, a DOCSIS 3.1 modem, on the Xfinity gigabit plan and used this ASUS Wi-Fi 6 router for two weeks. During this period, I performed several activities, closely observed the device in several parameters, and finally here to put my honest views.

Wireless Speeds & Suitability

ASUS AX6000 dual-band Wi-Fi 6 router comes with a total capacity of 6 Gbps. The individual band speeds are distributed as:

2.4 GHz: 1148 Mbps5 GHz: 4804 Mbps

With an Xfinity Gigabit plan, on the 5 GHz frequency, the download speed reached 897 Mbps and the upload speed clocked 39.5 Mbps, within the 15 feet distance of router placement.

ASUS RT-AX88U Speed Test

A couple of rooms away, approximately 70 ft away from the router, the downloads were raking up 580 Mbps, where the uploads dropped to 29 Mbps. And as you’d expect from a heavy-weight router, the speeds on 2.4 GHz frequency were also impressive.

In the 15 ft area, the router recorded downloads at 789 Mbps and uploads at 32 Mbps. At the farthest point, outside the house in the front yard, the downloads were hitting 105 Mbps and uploads 14 Mbps.

ASUS RT-AX88U Gaming Features

The gaming acceleration and VPN make it one of the favorite candidates for households with gamers. It eased through multiplayer gaming and streaming sessions with no lags‌.

WiFi Coverage & Devices Capacity

ASUS RT-AX88U Coverage

The four huge beamforming antennas claim the router to cover homes as large as 3,000 Sq Ft. My test lab, measuring over 2,500 Sq Ft was under the full blanket coverage of the router, standing true to the official RT-AX88U range.

The combination of 160 MHz channels, OFDMA, and MU-MIMO is a game changer. Even with over 30 devices hogging down the internet, there were hardly any noticeable drops in the performance with 2 smart TVs, work station, smart home appliances, and a plethora of mobile gadgets sharing the internet.

Design & Wired Connectivity

ASUS RT-AX88U Design

ASUS distributes the ventilation across the front, rear, and underneath the sleek-looking router. An angled design in a black firm plastic chassis weighs 2.1 lbs and measures 11.8 x 7.4 x 2.4 inches.

That’s going to gobble up some space on your table. You’ll find all the ports lined up on the rear, with an exception of USB 3.1 on the front.


With 8 gigabit Ethernet ports, you’ll not run out of wired connectivity options for the priority gadgets. The LAN aggregation will allow you to combine multiple connections.

The Ethernet ports are tightly packed, so the bigger hands should play it a little soft. My workstation raked downloads soaring above 970 Mbps, with uploads maxing out at 42 Mbps.

Security Features

ASUS RT-AX88U Security

One area where ASUS excels from its competitors. Apart from offering WPA3 encryption standards, a comprehensive time-based access schedule, and parental controls, RT-AX88U comes with commercial-grade AiProtection.

A two-way intrusion protection system, malicious content blocking protects you from the vulnerabilities of the internet. Periodic vulnerability assessments and quarantine keep the infected device from affecting the other devices connected to the network. All the extra features come to you at no additional cost.


You can either choose to use the web-based installation or the ASUS router mobile app. The interface is similar and helps you breeze through the process with a structured approach.

The device was up and running in less than 15 minutes. Be wary of changing settings too often, where applying the changes took its sweet time.

Enable remote management in the web portal, and you’ll be in charge of the internet connection, even when you are away from home.

Hardware & Other Features

ASUS RT-AX88U Hardware

ASUS relies on a Quad-Core processor clocking at 1.8GHz on a Broadcom chipset to dictate the terms, which it does with ease. The 1GB RAM and 256MB storage play a critical role in keeping the network stable during tedious data-intense tasks like twitch streaming, online gaming, and 4K streaming.
