The Asus RT-AC54U router has a MediaTek MT7620A @ 580 MHz processor. You cannot expand the router's memory (64 MB). When choosing a router, it is important to consider the RAM specifications. A larger flash memory allows for more space to store configuration backups. Asus often releases firmware updates. They improve the router's features, security, and bugs. They also add new features. The 12 V / 1 A PSU provides power to the router. If it breaks, you can replace it with a new one.

The router supports many networking standards. It ensures compatibility with different devices and systems. 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. The WAN port on the RT-AC54U router is a Fast Ethernet port, not a Gigabit Ethernet.

The RT-AC54U router supports 3G or 4G dongles, allowing you to connect to a cellular network. OpenVPN is popular for VPNs. This is because it is strong, flexible, and works on many devices. PPTP has known flaws. These include problems with the encryption and the risk of password cracking.

This router has 2 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. The 5 GHz band is less crowded. This leads to less interference and a clearer wireless signal. The RT-AC54U router is 5 GHz capable. This Wi-Fi router supports multiple spatial streams, typically up to 4 streams.

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.

The USB 2 port has a maximum theoretical data transfer rate of 480 megabits per second (Mbps). 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.
