TUF-AX4200 wireless network performance, signal test

The wireless router testing environment is located around 70 pings near company B1, with the TUF-AX4200 situated at the central location for internet connectivity. The test employs an MSI Prestige 14 802.11ax laptop, using Acrylic Wi-Fi Analyzer and Speedtest as testing tools; the company’s network speed is rated at 1000M/600M.

For the network testing, the initial focus is on assessing the signal coverage strength and network speed performance. Hence, the MSI Prestige 14 802.11ax laptop is utilized as the testing device, connected to the 2.4GHz and 5GHz wireless networks of the TUF-AX4200, achieving connection speeds of up to 2.4 Gbps.

TUF-AX4200 5GHz up to 2.4Gbps connection speed.

The optimal signal location, also known as the KING position, is approximately one meter from the router. At this distance, the 5GHz frequency can achieve internet speeds of 918Mbps/504Mbps, while the 2.4GHz frequency can reach up to 211Mbps. Despite the presence of pillars and shelves at diagonal point A, the wireless signal strength and speed remain fairly robust with no partition wall.

However, locations D (storage room) and E (inside the room), which are somewhat further away, are obstructed by wooden partitions, shelves, and other items, leading to relatively weaker 2.4GHz and 5GHz signals.

The TUF-AX4200’s wireless signal coverage is well-suited for standard homes, small to medium-sized offices, and even larger workplaces. However, when the distance increases or there are numerous obstacles, the 2.4GHz connection may slow down slightly. Nevertheless, a 5GHz connection should still allow for normal usage, such as scrolling through Facebook.

The intranet transmission test for the wireless network involved using the TUF-AX4200 as a wireless router, a 1GbE LAN connection serving as an iPerf3 server and a computer for file sharing, and an MSI Prestige 14 802.11ax laptop with an Intel Wi-Fi 6 AX201 160MHz network card for testing.

The iPerf3 command used for the TCP bandwidth test was –c server ip –w 50M –t 120 –i 10.

The TUF-AX4200 was able to achieve a transmission bandwidth of 940 Mbits/s from 1GbE LAN to 1GbE LAN, which is the base capability of 1GbE. With the WiFi 6 802.11ax 5GHz wireless transmission, it could also reach a transmission capacity of 934 Mbits/s, while the 2.4GHz frequency was able to achieve 112 Mbits/s.

To further understand the real-world file transfer performance of Wi-Fi 6, a test was conducted using Windows Network Neighborhood to transfer files. FastCopy software was used to upload a single 30GB file from the client computer to the shared folder on another computer.

The TUF-AX4200 demonstrated a baseline transmission capability of 107.6 MB/s from 1GbE LAN to 1GbE LAN, and a wireless transmission performance of 105.9 MB/s on Wi-Fi 6 802.11ax 5GHz. This ensures users needing intranet transmission can enjoy wireless transmission performance comparable to that of a wired network.

TUF-AX4200 file transfer speed.


The performance of the TUF Gaming AX4200 wireless router, in terms of signal strength and speed, is on par with the previously tested TUF-AX5400. Upgrading to a 2.5GbE WAN would only be beneficial if the ISP’s internet network exceeds the speed of 1GbE. The new TUF-AX4200 is well-equipped to meet the requirements of a typical household 1GbE network environment, and it can match the transmission capabilities of a wired connection under the Wi-Fi 6 160MHz bandwidth.

Furthermore, the TUF-AX5400 wireless router is priced at NT$4,790, making it a more cost-effective choice compared to its own AX3000 model. It also retains popular features such as ASUS’s exclusive mobile game acceleration, Open NAT, and AiProtection parental monitoring, making this older model a great deal.
