The 3 x 5 dBi, RP-SMA antennas allow sending and getting many data streams at once. This boosts overall throughput and improves Wi-Fi performance. Many IoT devices, smart home devices, and older Wi-Fi devices mainly use the 2.4 GHz band. To optimize your Wi-Fi experience, it's often recommended to use a combination of both 2.4 GHz and 5 GHz bands. The Wi-Fi router offers fast data speeds. They are good for streaming HD video, online gaming, and large file transfers.

The top speed, 600 + 1300 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.
