The Asus RT-N18U router has a Broadcom BCM47081A0 @ 800 MHz processor. The 256 MB of RAM enables the router to handle multiple tasks and processes concurrently. Flash memory retains its data even when the router is off. This allows the router to keep its firmware and settings across reboots. Asus often releases firmware updates. They improve the router's features, security, and bugs. They also add new features.
Using a custom OS on a router has benefits. But, it also has risks. The 12 V / 1.5 A PSU provides power to the router. If it breaks, you can replace it with a new one.

Like many modern routers, the Asus RT-N18U 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-N18U 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. It allows secure communication over an insecure network, such as the internet.

This router has 3 x 5 dBi, RP-SMA antennas. Antennas are key parts of wireless routers. They send and receive radio signals to make wireless connections. Many IoT devices, smart home devices, and older Wi-Fi devices mainly use the 2.4 GHz band. This is a Wi-Fi 4 (802.11n) router. Wi-Fi 4 improved the range and coverage compared to previous Wi-Fi standards.. The top speed, 600 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.
Connectivity

The USB 2 port has a maximum theoretical data transfer rate of 480 megabits per second (Mbps). The USB 3 ports provide a fast interface for external storage with data transfer rates of up to 4.8 Gbps. USB print servers let you connect a USB printer to your network. This makes it accessible to many devices. You can connect external storage devices such as USB flash drives or USB hard drives to your router.
