Description
The TP-LINK ARCHER AX21 is a next-generation Wi-Fi 6 router designed to provide a significant upgrade in wireless network performance. With an AX1800 speed rating, it offers combined speeds of up to 1800 Mbps across its dual bands (574 Mbps on 2.4GHz and 1201 Mbps on 5GHz). This router utilizes the latest Wi-Fi 6 (802.11ax) standard, which brings substantial improvements over previous Wi-Fi generations, including higher efficiency, lower latency, and greater capacity.
