The AC1900 MU-MIMO Wi-Fi router offers built-in security features to protect your network and connected devices. The IPv4 uses 32-bit addresses, represented as four sets of numbers separated by periods (e.g. The AC1900 MU-MIMO Wi-Fi router also supports IPv6 protocol, allowing you to utilize the latest version of the Internet Protocol. The LAN ports are physical connectors on a AC1900 MU-MIMO Wi-Fi router that allow you to connect devices to your local network using Ethernet cables.

This router has Gigabit Ethernet LAN ports. If you have a high-speed internet plan that offers speeds of 1 Gbps or higher, gigabit Ethernet ports are essential to fully utilize the available bandwidth. WAN ports often require specific configuration settings based on the type of internet connection provided by your ISP. The AC1900 MU-MIMO Wi-Fi router supports Gigabit speed on its WAN port, that can support speeds up to 1000 Mbps. This router ensures that you can fully utilize high-speed internet connections provided by your ISP.

The 4 x 4 dBi, fixed antennas of AC1900 MU-MIMO Wi-Fi influence the quality and stability of the Wi-Fi signal. A properly positioned and well-designed antenna can minimize interference and signal degradation, leading to a more reliable and stable connection. This router is 2.4 GHz compatible. The 2.4 GHz band is widely supported by a wide range of devices, including older devices that may not be compatible with the 5 GHz band.

The AC1900 MU-MIMO Wi-Fi supports 5 GHz signals. Most modern devices, such as smartphones, tablets, laptops, and smart TVs, support dual-band Wi-Fi, which means they can connect to both 2.4 GHz and 5 GHz networks. By utilizing the 5 GHz band, you can offload some devices from the crowded 2.4 GHz band, reducing congestion and improving overall network performance. The AC1900 MU-MIMO Wi-Fi AC Wi-Fi router is backward compatible with older Wi-Fi devices that support 802.11a/b/g/n standards.

The AC1900 refers to the maximum combined data transfer rate supported by the router across all Wi-Fi bands. The AC1900 MU-MIMO Wi-Fi is capable of a maximum throughput speed of 600 + 1300 Mbps. The real-world speed of a AC1900 MU-MIMO Wi-Fi router is typically lower than its theoretical maximum speed. The TX power of AC1900 MU-MIMO Wi-Fi can be adjusted by the user or set automatically by the router firmware. Higher TX power values indicate stronger signal transmission, which can result in a larger coverage area.

The AC1900 MU-MIMO Wi-Fi router offers several security protocols: WPA, WPA2, WPS. The WPA2 (Wi-Fi Protected Access 2) was introduced as an improvement over WEP and provides stronger security. If WPA3 is not available, WPA2-Personal with AES encryption is still considered secure. The AC1900 MU-MIMO Wi-Fi router offers WPS. The WPS (Wi-Fi Protected Setup) provides a simplified and convenient method for connecting devices to a Wi-Fi network. Instead of manually entering the Wi-Fi network name (SSID) and password, users can use the WPS feature to establish a connection with the push of a button or by entering a PIN. The D-Link AC1900 MU-MIMO Wi-Fi router is capable of creating a guest network. Guests connected to the guest network usually have limited access to network settings and configurations. They are typically restricted from accessing devices connected to the primary network, such as printers, network-attached storage (NAS), or other shared resources.
