Like many modern routers, the RT-AC55U supports many network standards too. 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. This router has Gigabit Ethernet LAN ports. They provide data transfer speeds of up to 1000 Mbps (1 Gbps) over Ethernet connections.
This router ensures that you can use fast internet from your ISP fully. The RT-AC55U router supports 3G or 4G dongles, allowing you to connect to a cellular network. OpenVPN is a full-featured SSL VPN solution. It uses OSI layer 2 or 3. It extends secure networks using SSL/TLS, an industry standard. IPsec is a widely used network protocol suite. It provides security for IP communications. The PPTP is an older VPN protocol. It was widely used in the past.

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. This router is 2.4 GHz capable. The 2.4GHz band refers to the portion of the radio spectrum between 2.400 and 2.4835 gigahertz. The 5 GHz band offers better noise immunity and less interference. It also has more available channels. Wi-Fi 5 uses the 5 GHz band. It uses wider channels and advanced techniques to send data faster.
Real-world RT-AC55U router speeds are lower than its theoretical maximum speed. 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.
Connectivity
