A well-positioned antenna can reduce interference and signal weakening. This leads to a more reliable connection. The 2.4 GHz band is widely supported by many devices. This includes older ones that may not work with the 5 GHz band. The 5GHz band provides faster data transfer speeds compared to the 2.4GHz band. This Wi-Fi router supports multiple spatial streams, typically up to 4 streams. The top speed, 300 + 1733 Mbps, is the highest data rate the router can reach. It's the theoretical limit in perfect conditions.

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.
