Like many modern routers, the RT-AX88U supports many network standards too. The IPv4 uses 32-bit addresses, represented as four sets of numbers separated by periods (e.g. 192.168.0.1). The router also supports IPv6. This allows you to use the latest Internet Protocol. 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.

You can connect the 3G/4G USB dongle to the USB port on the RT-AX88U router. 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. The PPTP is an older VPN protocol. It was widely used in the past.

A well-positioned antenna can reduce interference and signal weakening. This leads to a more reliable connection. The 2.4 GHz band is widely supported by many devices. This includes older ones that may not work with the 5 GHz band. Using the 5 GHz band can move some devices from the crowded 2.4 GHz band. This cuts congestion and boosts the network. This AX Wi-Fi router provides much faster data transfer rates. It is faster than older Wi-Fi standards.

Real-world RT-AX88U 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. WPS (Wi-Fi Protected Setup) provides an easy method. It connects devices to a Wi-Fi network.
