Asus is known for its high-end electronic products including wireless routers. The new Asus RT-AX56U (Ax1800) is one of the best Wi-Fi router device of the company. Many people consider this model for a wide variety of state-of-the-art features and affordable price.

Even though this device comes with an affordable price, it goes in line with other product that has 802.11ac technology. For instance, it has similar features like Asus RT-AC86U and the Netgear X4S routers.

Asus RT-AX56U uses 1024-QAM technology for wireless connection. The router also takes benefit from the OFDMA technology to enhance multi-user access. However, we didn’t find the 160MHz channel bandwidth but there is the AI-MESH support system. If you run the router with devices that are compatible with Wi-Fi 6 adapters, you won’t see any performance differences.

Recently, we tested the new Asus RT-AX56U for wireless performance and we found it impressive. There are a few issues related to compatibility but overall, it is a good Wi-Fi router. In today’s article, we will review the Asus RT-AX56U (Ax1800) wireless router and talk about its features in detail. We will share our experience with the router. Read on!

While testing the networking performance of the router, we connected it with the 5GHz network on 80 MHz bandwidth channel from the client-side to the server-side.

We observed that at 5 feet distance, the average speed was 825 Mbps. When we checked the speed at 15 feet, it was 646 Mbps. So, there was no notable difference. Also, at 30 feet, we measure the average speed of the router was 329 Mbps.

The performance of the router at close range was similar to the performance of the Asus RT-AX58U. Also, we checked the speed of the router on the service-client side. We found that at 5 feet, the speed of the device was 385 Mbps and at 15 feet, we measured 317 Mbps on average.

Also, at 30 feet, the speed of the device was 228 Mbps. We compared the performance of the server-client side with that of the client-serve side – and the results were similar. There was no notable difference between the two.

After that, we switched to a 2.4 GHz network and on the client to the server side, we measured 355 Mbps at 5 feet and 222 Mbps at 15 feet. However, at 30 feet, the speed of the device was 123 Mbps. We think that these are good results showing the compatibility of the router with most devices.


Experts say that Asus RT-AX56U and Asus RT-AX58U has similar design features. However, we found that there are a few differences between the two models, especially in the internal hardware design. Asus RT-AX56U has an ultra-compact plastic case. It is covered with a black matte finish.

The device is soft-to-touch. There are 2 antennas on the backside. These antennas are non-removable. Compared to the 4 antennas of the Asus RT-AX58U, the antennas of the RT-AX56U does not look sturdy. Also, these antennas are not longer than the RT-AX58U, which are 7.24 inches long.

Unlike its competitor router devices, Asus RT-Ax1800 has a compact design. The measurements are 8.79 x 5.09 x 1.87 inches. Thus, this device is aesthetically attractive to most users. It is designed in such a way that you can mount it on the wall or ceiling using a few of the dedicated holes from the device’s bottom.

Besides, the weight of the device is 16 pounds but still, this device is lightweight than most of its competitors. It has 4 feet made of silicone material that helps keep the router intact on the desk even if you have connected many cables to it.

When we analyzed the top of the device, there is a logo of the company and LED indicators. Also, there are a few ventilation grills, which are positioned stylishly. On the rare side of the router, you will find the ports area.

Besides, Asus is known for its intuitive nature of LED indicators and on this device, they are at the top side. On the front side of the device, there are 4 LAN LEDs and each one is for the LAN port, which is followed by the WAN LED.

The WAN LED will indicate red light when there is no internet connection. On the other hand, it will indicate white light after the internet connection is established. There is 1 LED indicator for the 5 GHz frequency network and 1 for the 2.4 GHz frequency network. Both these LED indicators flash at the time of sending and receiving of the data. Also, there is an LED indicator for power.


When we remove the metallic plate of the device, we found that this device has a Broadcom BCM BCM6755KFEBG chipset with quad-core technology. The clock speed is 1.5 GHz. Asus Ax1800 comes with 512 MB RAM and has a single-port transformer module with a Broadcom BCM531340KFBG switch chip.  

In addition, this router uses the Broadcom BCM6755 chip for the Wi-Fi performance. It has integrated modules for the 2.4 GHz band with the support of the Broadcom BCM6755 chip. When it comes to the 5 GHz band, it has front-end modules, which are integrated with a few Skyworks 85743 bands.

Asus RT-Ax1800 is a high-performance router with a maximum theoretical transfer of data, which is 1,201 Mbps on the 5GHz band. The maximum data transfer rate on the 2.4 GHz is 574 Mbps.


The process of installation for all routers manufactured by Asus is the same. First, you need to plug in the Ethernet cable to the modem and connect the power cable. Once done, you can switch on the power.

When it comes to the configuration of the device, you can do this in two ways, which are through the web-based interface or the app. It is better to carry out the process of installation through the web-based interface because it is faster and easier.
