## Long description

D-Link DIR-878/MT AC1900 MU-MIMO Gigabit is a dual-band wireless router designed for home and small-office networks. It supports 802.11ac Wi‑Fi with combined throughput up to AC1900 (up to 600 Mbps on 2.4 GHz and up to 1300 Mbps on 5 GHz), MU‑MIMO technology for concurrent device connections, and Gigabit Ethernet ports for reliable wired access. The router includes four external antennas, beamforming (AC SmartBeam) for directed signal coverage, a dual-core processor to handle multiple streams, and standard security features such as WPA/WPA2 and WPS.
Advantages
The DIR-878/MT offers simultaneous dual‑band performance to separate bandwidth-hungry applications on the 5 GHz band from legacy devices on 2.4 GHz, improving overall network efficiency. MU‑MIMO support helps maintain throughput when multiple devices stream or game at the same time. External antennas combined with AC SmartBeam enhance coverage and signal directionality while the built‑in Gigabit WAN and four Gigabit LAN ports provide stable high-speed wired connections. A dual-core processor and three spatial streams (3x3) increase throughput and responsiveness for connected devices.
Suitable for
 HD video streaming and 4K media playback
 Online gaming with reduced lag
 Multiple simultaneous device connections in homes or small offices
 Wired devices requiring Gigabit Ethernet

How to use
Connect the router's Gigabit WAN port to your DSL or cable modem and plug the power adapter into a mains outlet. Use an Ethernet cable to connect wired devices to the LAN ports as needed. Access the router's web-based setup via a browser on a connected device (supported browsers include recent versions of Chrome, Firefox, Internet Explorer and Safari) to run the initial configuration wizard, set Wi‑Fi network names (SSIDs) for both bands, and apply a secure password. Enable WPA/WPA2 and configure WPS only if necessary.
Usage recommendations
Place the router centrally and elevated in the coverage area to maximize AC SmartBeam effectiveness and reduce physical obstructions. Use the 5 GHz band for latency-sensitive tasks such as gaming and 4K streaming, and keep less demanding or legacy devices on 2.4 GHz. Keep firmware updated and use WPA/WPA2 security with strong passphrases; disable WPS if not required to reduce potential security risks.
