In the world of high-speed internet, latency is a critical factor that impacts online gaming, streaming, and overall network performance. With the advent of Wi-Fi 6 technology, routers like the Archer AX21 and Archer AX90 from TP-Link have become popular choices for consumers seeking low latency and fast connectivity. This article compares the networking latency of these two devices to help users make informed decisions.
Understanding Networking Latency
Networking latency refers to the time it takes for data to travel from the source to the destination across a network. Lower latency results in quicker response times, which is especially important for online gaming, video conferencing, and real-time applications. Several factors influence latency, including hardware quality, Wi-Fi standards, and network congestion.
Overview of the Archer AX21 and Archer AX90
The TP-Link Archer AX21 and AX90 are both Wi-Fi 6 routers designed to deliver high-speed internet with improved efficiency. The AX21 is a more budget-friendly option, while the AX90 offers advanced features and higher throughput. Understanding their specifications helps contextualize their performance in latency testing.

Archer AX90 Specifications
- Wi-Fi Standard: 802.11ax (Wi-Fi 6)
- Tri-band (2.4 GHz, 5 GHz, 5 GHz)
- Maximum Speed: Up to 574 Mbps (2.4 GHz) + 4804 Mbps (5 GHz) + 4804 Mbps (5 GHz)
- Processor: Quad-core 1.5 GHz
- Ports: 4 Gigabit Ethernet ports + 1 2.5 Gbps Ethernet port
Methodology of Latency Testing
Latency was measured using a standardized testing environment. Both routers were connected to the same modem and tested using a high-performance laptop. The tests included ping measurements to a local server and international servers to simulate real-world conditions. Multiple tests were conducted at different times to account for network variability.
Results and Analysis
Local Network Latency
In local network tests, the Archer AX90 consistently showed lower latency, averaging around 1-2 milliseconds. The AX21 averaged slightly higher, around 3-4 milliseconds. The additional processing power and tri-band capability of the AX90 contribute to its superior local performance.
Internet Latency to International Servers
When pinging international servers, the AX90 maintained lower latency, averaging 20-30 milliseconds, whereas the AX21 averaged around 35-45 milliseconds. The higher throughput and more advanced hardware in the AX90 enable it to handle data transmission more efficiently over longer distances.
Implications for Users
For gamers and professionals relying on real-time data transfer, the Archer AX90 offers the advantage of lower latency, reducing lag and improving responsiveness. The AX21 still performs well for everyday tasks and streaming but may not be ideal for latency-sensitive applications.
Conclusion
Both the Archer AX21 and AX90 are capable Wi-Fi 6 routers that deliver fast internet speeds. However, when it comes to networking latency, the AX90 outperforms the AX21 due to its tri-band setup and more powerful hardware. Users seeking the lowest possible latency should consider the AX90, especially for gaming and professional use.
