Product Description

Design and Features
The wedge-shaped DIR-878 has a matte-black finish and measures 1.7 by 7 by 10 inches (HWD). It’s designed to sit on a flat surface, or it can be hung on a wall using the two built-in mounts. It features four non-removable, adjustable antennas and has four Gigabit LAN ports, a WAN port, and reset, WPS, Wi-Fi, and power buttons, all at the rear of the cabinet. The top of the router holds LED indicators for power, internet connectivity, and each radio band. Included in the box are a LAN cable, a Quick Install guide, and a Configuration Card.

The DIR-878 is powered by a dual-core 880MHz CPU. It’s a dual-band 802.11ac router capable of speeds of up to 600Mbps on the 2.4GHz band and 1,300Mbps on the 5GHz band. It supports the latest 802.11ac technologies, including beamforming, which send signals directly to each client rather than over a broad spectrum, MU-MIMO streaming, which serves data to compatible clients simultaneously rather than sequentially, and Smart Connect, which automatically selects the best radio band for optimal throughput.

D-Link AC1900 MU-MIMO Wi-Fi Router (DIR-878)

You manage the DIR-878 using the same easy-to-use web-based console as the D-Link AC1200 Wi-Fi Router (DIR-842)$59.99 at Amazon or via the D-Link Quick Router Setup (QRS) mobile app for iOS and Android. The web console’s home screen has a network map that shows the number of connected clients. Click the client icon to see who is connected, their IP address, and if parental controls are enabled. Under the Settings tab, you’ll find a Setup Wizard and menus for configuring Internet, Wireless, and Network settings. Use the Wireless settings to configure Security Mode settings, 802.11 Mode settings, Wi-Fi Channel selection, Channel Width, and Transmission Power settings.

The Features tab offers a user-friendly drag-and-drop Quality of Service (QoS) engine, firewall settings, web-filtering settings, and port-forwarding settings. In the Management menu, you can create parental control rules, set up access schedules, view system logs, update the router’s firmware, monitor network traffic, and change passwords.

Installation and Performance
Installation is easy. Once the router was connected to my PC and to the internet, I typed http://dlinkrouter.local in my browser’s address bar and used the Setup Wizard to configure my internet and basic wireless settings. The entire process took around three minutes. I then set about creating unique passwords and SSIDs for each band (I disabled Smart Connect to test 2.4GHz and 5GHz performance separately), and the router was ready for throughput testing.
