This router has 2 x 2 dBi, internal antennas. Antennas are key parts of wireless routers. They send and receive radio signals to make wireless connections. 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 5 GHz band is less crowded. This leads to less interference and a clearer wireless signal. The AirStation AC1200 router is 5 GHz capable.

The Wi-Fi router offers fast data speeds. They are good for streaming HD video, online gaming, and large file transfers. 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.
