This router has 2 x 4 dBi, fixed antennas. Antennas are key parts of wireless routers. They send and receive radio signals to make wireless connections. Many IoT devices, smart home devices, and older Wi-Fi devices mainly use the 2.4 GHz band. The 5 GHz band offers better noise immunity and less interference. It also has more available channels. This router is a Wi-Fi 6 router. 802.11ax is the sixth-generation Wi-Fi standard, commonly referred to as Wi-Fi 6.

Real-world RT-AX56U router speeds are lower than its theoretical maximum speed. WEP was the first Wi-Fi security protocol. But it is now seen as weak and easy to hack. The introduction of WPA2 (Wi-Fi Protected Access 2) improved upon WEP. It provides stronger security. WPS (Wi-Fi Protected Setup) provides an easy method. It connects devices to a Wi-Fi network.
