Asus RT-AC1900P Review

Asus RT-AC1900P AC1900 Dual-Band WiFi Router with ASUS Router app and AiProtection, supporting AiMesh - mesh networking whole home wifi system

If you’re searching for a router that will provide you with fast Wi-Fi in your house for less than $200, the Asus RT-AC1900P Dual-Band Wireless AC-1900 Gigabit Router ($179.99) should be at the top of your shortlist.

The RT-AC1900P, which is intended for medium to large homes, performed admirably in our 2.4GHz and 5GHz throughput tests, and it comes with a robust feature set that includes four Gigabit LAN ports, two USB ports, a plethora of management options, and protection against malicious websites and infected clients.

Although it does not enable Multi-User Multiple Input, Multiple Output (MU-MIMO) data streaming and its file-transfer rates are just average, it is still worth considering if you have a tight budget.

Design and Features

According to the manufacturer, the RT-AC1900P ($197.31 at Amazon) is identical in appearance to the RT-AC68U Dual-band Wireless-AC1900 Gigabit Router ($149.99 at Best Buy), which it replaces in the Asus router range. The gadget has a glossy black, textured surface and measures 6.2 by 8.6 by 3.2 inches. It is supported by a vertical stand and has a glossy black, textured appearance (HWD).

Three removable and adjustable antennas protrude from the top of the router, and there are ten blue LED status lights along the bottom: four for LAN activity, one for WAN activity, two for USB connectivity, two for Wi-Fi connectivity, and one for power. The router is equipped with three removable and adjustable antennas, and it has three removable and adjustable antennas.

There are four Gigabit LAN connections, a WAN port, a USB 3.0 port, a USB 2.0 port, a power button, and an On/Off button for the LED light on the back of the computer. The WPS button and the Wi-Fi On/Off button are located on the right side of the router.

Among the features are an Intel Atom Z3735F dual-core CPU, 256MB of RAM, and 802.11ac circuitry that enables AC1900 Wi-Fi, which can deliver up to 600Mbps on the 2.4GHz band and 1,300Mbps on the 5GHz band.

This router is equipped with beamforming technology, which transmits data directly to clients rather than across a wide spectrum, however it does not support MU-MIMO data streaming, which sends data to compatible clients at the same time rather than in batches.

It is possible to control the RT-AC1900P either through a web-based management interface or using the Asus Router mobile application. The main screen of the console features menus for General and Advanced settings on the left, a Network Map in the center, and System Status information on the right. The console’s main screen is divided into three sections.

The router also comes with a built-in Setup Wizard that makes it simple to get it up and running quickly. Guest networking, a traffic analyzer, and AiCloud, which allows you to transform a connected USB drive into a cloud drive, are all included in the general settings. Also included is an application area for USB drives. This portion has support for iTunes, Samba, Time Machine, FTP-server, and print-server capabilities, among other things.


The RT-AC1900P is straightforward to set up, as is the case with the majority of routers, due to the previously stated Setup Wizard. When the router is plugged in and linked to a host PC and the internet, a browser page is instantly launched, allowing you to complete the Setup Wizard in minutes. In a matter of minutes, you may check the status of your internet connection and change the most basic wireless security settings.

The RT-AC1900P performed admirably in our throughput performance testing, earning top marks. In our close-proximity (same-room) 2.4GHz test, it scored 98Mbps, which was slightly faster than the Linksys EA7500 Max-Stream AC1900 MU-MIMO Gigabit Router (97.3Mbps) and the Synology Router RT1900ac (95.9Mbps), but a little slower than the D-Link AC3150 Ultra Wi-Fi Router (DIR-885L/R) ($ (108Mbps).

In our tests at 30 feet, the RT-AC1900P (75.8Mbps) outperformed the Linksys EA7500 (52.1Mbps) and the Synology RT1900ac (45.6Mbps), and it was slightly faster than the Trendnet TEW-827DRU (75.8Mbps) (75.3Mbps). The D-Link DIR885L/R took first place with an 85.5Mbps score.

It was particularly remarkable how well the 5GHz band performed. Despite having a higher score of 533Mbps than the Synology Router RT1900ac (479Mbps) and the Linksys EA7500 (495Mbps), the RT-AC1900P scored lower than the D-Link DIR-885L/R (572Mbps) and the Trendnet TEW-827DRU (572Mbps) (590Mbps). In the 30-foot test, its throughput of 337Mbps came in second only behind the D-Link DIR-885L/R (350Mbps). The Linksys EA7500 achieved 298Mbps, the Synology RT1900ac achieved 231Mbps, and the Trendnet AC2600 StreamBoost MU-MIMO WiFi Router (TEW-827DRU)($79.99 at Amazon) achieved 260Mbps.

Transferring a 1.5GB folder including audio, video, photo, and document files proved to be only a mediocre experience in terms of file transfer performance. In our write test, the RT-AC1900P achieved 34.2MBps and in our read test, it achieved 35.1MBps. These results were similar to those achieved by the D-Link DIR-885L/R (33.2MBps write and 44.1MBps read), but they fell short of our leader, the Netgear Nighthawk X10 AD7200 Smart WiFi Router (R9000) , which achieved 77.1MBps and 89.

The Asus RT-AC1900P Dual-Band Wireless AC-1900 Gigabit Router, which costs $180, delivers solid performance and a slew of useful features at a reasonable price. However, while its file transfer rates are below average, it provides excellent close-range and long-range throughput on both bands. With this router, you receive a broad set of I/O ports, as well as a slew of administration choices, including Trend Micro’s complete network protection software.

However, you will not be able to use MU-MIMO data streaming capabilities. True, there aren’t many clients that are compatible with many users simultaneously, but that will change in the near future. The D-Link AC3150 Ultra Wi-Fi Router (DIR-885L/R) is a good choice if you want a midrange router that is more future-proof. It provides superior all-around performance, supports MU-MIMO data streaming, and has open-source firmware, making it our Editors’ Choice in this category.
