A well-positioned antenna can reduce interference and signal weakening. This leads to a more reliable connection. Many IoT devices, smart home devices, and older Wi-Fi devices mainly use the 2.4 GHz band. Using the 5 GHz band can move some devices from the crowded 2.4 GHz band. This cuts congestion and boosts the network. Wi-Fi 5 uses the 5 GHz band. It uses wider channels and advanced techniques to send data faster.

Real-world EA6400 Smart Wi-Fi AC1600 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.
