This router has 6 x 3 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. Wi-Fi 5 uses the 5 GHz band. It uses wider channels and advanced techniques to send data faster.

Real-world RT6600ax router speeds are lower than its theoretical maximum speed. The introduction of WPA2 (Wi-Fi Protected Access 2) improved upon WEP. It provides stronger security. The WPA3 (Wi-Fi Protected Access 3) is the latest Wi-Fi security protocol. WPS (Wi-Fi Protected Setup) provides an easy method. It connects devices to a Wi-Fi network.
