A well-positioned antenna can reduce interference and signal weakening. This leads to a more reliable connection. The AirStation HighPower N600 DD-WRT NXT is compatible with 2.4 GHz Wi-Fi networks. Using the 5 GHz band can move some devices from the crowded 2.4 GHz band. This cuts congestion and boosts the network. This is a Wi-Fi 4 router, with slower data transfer speeds. This can result in slower downloads, video buffering, and reduced performance.

Real-world AirStation HighPower N600 DD-WRT NXT 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. WPS (Wi-Fi Protected Setup) provides an easy method. It connects devices to a Wi-Fi network.
