Like many modern routers, the Asus RT-AC87U supports many features and tech. They improve your network's connectivity and security. The IPv4 is the fourth iteration of the Internet Protocol (IP). It is the most widely used version of IP on the internet today. The latest firmware supports IPv6. It provides a system to identify and locate computers on networks. Gigabit Ethernet ports support data transfer rates of up to 1 gigabit per second (Gbps).

A Gigabit WAN port is helpful. It is useful when your internet plan supports high speeds. The RT-AC87U router supports 3G or 4G dongles, allowing you to connect to a cellular network. OpenVPN is available for many operating systems. These include Windows, macOS, Linux, Android, and iOS. PPTP creates a VPN tunnel between two endpoints.

This router has 4 x 4 dBi, RP-SMA 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 RT-AC87U 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, 600 + 1734 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.
