The dimensions and design of a router can impact its cooling capabilities. Routers with larger dimensions may have more space for internal cooling mechanisms. If you plan to mount your router on a wall or ceiling, the weight can affect the mounting process. It also affects the type of mounting hardware needed.

The Asus RT-N56U router has a Ralink RT3662F @ 500 MHz processor. The 128 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. OpenWrt is an open-source operating system. It provides customizable firmware for embedded devices, like routers and access points. The 19 V / 1.58 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-N56U 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. 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-N56U router supports 3G or 4G dongles, allowing you to connect to a cellular network.

This router has 3 x 5.1 dBi, 2 x 3.8 dBi, internal 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. The 5 GHz band is less crowded. This leads to less interference and a clearer wireless signal. The RT-N56U router is 5 GHz capable. 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, 300 + 300 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.
