The 4 x 5 dBi, RP-SMA antennas allow sending and getting many data streams at once. This boosts overall throughput and improves Wi-Fi performance. The router supports the 2.4 GHz Wi-Fi. To optimize your Wi-Fi experience, it's often recommended to use a combination of both 2.4 GHz and 5 GHz bands. This Wi-Fi router supports multiple spatial streams, typically up to 4 streams. The top speed, 300 + 867 Mbps, is the highest data rate the router can reach. It's the theoretical limit in perfect conditions.

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.
