D-LINK DIR 878 revision A1 is a router is an affordable dual band router that offers the most recent 802.11ac along with beam-forming feature that includes MU-MIMO data streaming from D-LINK. Currently, this router priced at a retailed of RM 475.00 at shopee.

I always recommend most of my readers to buy from OOKAS for their good services.

So the question is, does this router deliver what it promises?


This is a used router and, I bought it from its previous owner to explore the features offered in this router.


D-LINK Firmware: Hardware A1 (Malaysia)

DDWRT Firmware: Factory image initial flash & Webflash image (not included in the test)


Before un-boxing:

The box comes with a decent design explaining to the user on the features that comes with the router. Frankly speaking, I kinda like the design of the rear part of the box. Good job D-LINK.

After un-boxing:

Figure 4: The item comes with the router.

The router is pretty standard, as it comes with four non-detachable antenna’s, a power adapter, a Cat5e ethernet cable, a warranty card and a manual booklet.

Figure 5: The rear view of the router.

At the rear of the router, a single gigabit WAN port, four gigabit LAN port, power port, an on/off button, a wps button and a wi-fi on/off button were present. This router doesn’t come with any USB port which lead to big disappointment as, for such a pricey router, not even a single USB 2.0 port were given.


D-LINK DIR-878 rev A Spec
Figure 6: The specifications of the router. You can refer the full spec here.

The router is powered by 880MHz dual core CPU from MediaTek. For such router, I would say, it is quite powerful CPU used to control the router.


Once you finish setting up the router, the router will apply the credentials settings and direct you to the main interface. Once you have directed to it, go to Settings > Internet > VLAN.

Figure 7: The VLAN settings of the router.

Assign the respective VLAN ID’s for each LAN port. By default, LAN 4 should be reserved / addressed as an IPTV port.

I am pretty sure that, most of you will have a minor heart attack as, when you’re setting up your wireless SSID and password, you most probably didn’t encounter the settings for 5GHz wireless band. Do not worry. Once you set up the VLAN, hit to Settings > Wireless page and disable the “Smart Connect” feature.

I disabled the WPS to enhance the security of the router. It is highly recommended you to, disable the WPS feature of your home router despite which router brand you’re using currently.


Smart Connect feature enabled:

“Smart Connect can intelligently identify the device, decide what band would provide it with the best possible connection, and connect it to that band.”D-LINK

Figure 17: The Smart Connect feature enabled.

When the Smart Connect feature were enabled, the 2.4GHz and 5GHz settings stay inactive and only one stream of a chosen band (2.4GHz or 5GHz) can be used by your device. By enabling this feature, you’re restricted to change your wireless mode, wireless channel or change your wireless channel width because this feature will adjust the best solution for you.

Smart Connect feature disabled:

Once the Smart Connect feature were disabled, the wireless settings for both bands can be customized according to your needs by clicking the “advance settings” button.

The wireless settings for both bands are as below.

Standard wireless speedtest for both bands:

I summarized the performance in the form of a graph.

The download speed for both bands fluctuates as the distance increases.

wireless upload test

The upload speed for both bands fluctuates as the distance increases. However, I have to redo the test for the veranda at the downstairs as the wireless test shows an error in the upload test.

Iperf3 Testing

  • Supports DDWRT.
  • Decent wireless coverage.
  • Decent design.
  • Router able to handle more than 10 connected devices.
  • Presence of physical Wi-Fi on/off button.
  • Presence of ventilation holes to keep the router to stay cool.

  • No USB 2.0 or 3.0 port.
  • The antenna’s are non-removable.
  • Consume a large space.
  • Option for 40MHz channel width for 5GHz null.


The router has above average performance. Not the best router I tested so far, but, it does perform well to the test thrown at it. It has a decent wireless coverage, you can set up the reboot schedule, and this router able to handle up to 10 or more devices connected to it. This router most suitable for home use and for organizations, well, I for normal, non-professional use, then this router can be on your list.

As to conclude this post, this router delivers what it promises. You can opt for flash to third party firmware such as DDWRT if wish for more features.

My recommendation: 6.5/10.
