In the premium segment, the DIR-878 is a new member of the D-Link family of dedicated Wi-Fi radios, designed to achieve optimal performance in data transmission. It’s geared toward home-based, small-office users with up to 20 to 30 devices connected at the same time.
Despite the relatively high cost, compared with the dual-band Wi-Fi router products tested by the Lab, the DIR-878 excels with wide coverage Support for new technologies and features, combined with easy-to-set up and manageability, makes this product “more affordable.”
As soon as it hits the box, the DIR-878 impresses with its sleek, ballistic look in the award-winning Star Trek series, the sharp edges of the gaming-specific Wi-Fi router.
Heat-insulated slots along the side of the machine, 4 high-performance antennas that can not be removed but are easily rotated, add a strong feel to the product.
The front panel is equipped with four status lights that connect to the Internet, the source and the two network frequencies, which are located in a convenient position so that it is easy to see whether the router is placed in any position.
The latter is the focus of the overall connectivity of the device, including four Gigabit LAN ports, Gigabit WAN ports. However, the DIR-878 does not have the same USB port as the DIR-880L.
Not only does it excel in appearance, it is also a highlight of the DIR-878. More specifically, D-Link has drastically equipped the DIR-878 dual-core processor, clocking up to 880MHz to meet the needs of multi-tasking Internet access for multiple users. In addition, the DIR-878 is capable of speeds up to 600Mbps on the 2.4GHz band and 1.300Mbps on the 5GHz band, supporting the highest 802.11ac standard at present.
The trendy MU-MIMO technology will allow the router to increase the ability to transmit multiple streams of data to up to three devices at the same time, allowing multiple users to perform multiple operations on multiple devices at the same time without much effect on system performance.
Notably, the Advanced AC SmartBeam technology helps to improve coverage by direct bandwidth solution to the devices connected in the network rather than simply transmitting bandwidth in the usual way.
Tested at the DIR-878 in a café’s space, I found that the DIR-878’s waveform quality was fairly steady and intense, almost surpassing the available sources.
At the end of the week, with a relatively large number of mobile devices connected at the same time (about 20 to 30 devices), the DIR-878 is very well coordinated to provide bandwidth for each receiver and no complaints. When using this router’s Wi-Fi network.
The DIR-878’s read / write performance over the Wi-Fi network is impressive, but not as bad as the Linksys EA7500 or Asus RT-180N.
Accordingly, I used the Lan Speed dedicated meter to test the data transfer capability of the DIR-878’s standard 5GHz AC on the two computers.
The test was performed simultaneously on two different computers connected to the 5Ghz band of the DIR-878.
In addition, I found that the coverage of the router is quite good, the average distance that waves can reach is between 30 and 35 m in the environment is the flat level apartment 4 floor with the object is wall and some household items.

Simple configuration and management
As mentioned above, super-easy configuration and management is one of the things that make up the DIR-878. Even “amatuer” users just need a few simple steps to get the device ready for operation.
Accordingly, after connecting the power supply and the WAN port to the upper level modem / router, users only need to use the browser to access the configuration page via the http: //dlinkrouter.local
For the first time, the DIR-878 will provide a quick Quick Wizard interface. Follow the prompts displayed and wait for a moment to reboot as the router is ready.
According to the manufacturer, the router supports quick setup via the D-Link Quick Router Setup (QRS) application on smartphones running iOS and Android operating systems, which can be downloaded free of charge from the store. Google Play Store and Apple App Store.
However, from the actual use on the Android smartphone, I found that QRS configuration is almost impossible. In the first configuration, when you go to the Connection section, QRS will display a pop-up dialog box informing you that you need to connect the network cable to the router. The test lab also followed the instructions, but the QRS prompted the error and stopped working. Next, back to the QRS interface, this application asks for the router’s administrative password while this operation has never been done before.
On the Home screen, the DIR-878 has almost no improvement over the DIR-880L’s predecessor, or some other D-Link Wi-Fi router product. Specifically, this router still apply the management model through network diagrams on the main interface, users just need to click on the icon to display the corresponding function.
For example, for the Internet icon, the DIR-878 will provide technical specifications related to the network.
When you click on the “DIR-878” router icon, you will get the IP4, IP6, and quick access settings on your device’s default SSID. In the SSID setup interface, you can also activate the Guest Access network through two sliders that correspond to the 2.4Ghz and 5Ghz bands. The lab found that the DIR-878 does not have a separate parameter setting for each 2.4Ghz and 5Ghz bands, but instead the router automatically splits two bands into one.
The Connected Clients option gives you information about which devices are connected to the router. Here, the user can also create rules (Rules), activate Parent Control (management time Internet access) …
The above feature tags allow you to customize advanced network settings such as QoS, Firewall, Port Forwarding, Website Filtering, Static Routing, Dynamic DNS, Quick VPN, Port Forwarding, Website Filter, and Static Routes.
The drag-and-drop QoS interface allows users to customize the Highest, High, or Medium priority on each device connected to the router.
Tab Management will provide customizable options for you to easily change time-related specifications, view system logs, set up email notifications for system events, and more.
Every product prepare launcher and provide on release date will be unboxing and check to bring full specifications & details features, service manual even suggest choose accessories. Thank for visting and sharing !
