This is the TP-Link Archer AX73, a Wi-Fi 6 compatible router. It offers a maximum Wi-Fi speed of 5400Mbps and covers a wide area with its six high-performance antennas. With dual-band 6-stream and Gigabit support, it delivers high performance even when many devices are connected. It features a powerful 1.5GHz triple-core CPU and can connect to more devices with OFDMA+MU-MIMO. Recommended usage environment is a 3LDK apartment or a 4LDK house, supporting up to 80 connected devices. It supports WPA3 and HomeShield, ensuring security. There are no noticeable scratches, but there is some wear and tear, so please purchase only if you are comfortable with a used item. I was using it without any problems until the listing date of January 3rd.
