D-Link DIR-885L

Under Construction!
This page is currently under construction. You can edit the article to help completing it.

The D-Link DIR-885L router was initially introduced in December 2015, and although discontinued in January 2019, could still be purchased new or refurbished via various regional Amazon sites well into 2021. This dual-band router contains a 1.4GHz dual core processor, 128MB of flash memory, and 256MB of RAM, which makes it an acceptable OpenWrt candidate. Its wireless hardware is capable of obtaining transfer rates of 1000Mbps in the 2.4GHz band and 2167Mbps in the 5GHz band. It has a 1Gbps WAN port, four 1Gbps LAN ports, and a single USB 3.0 port.

D-Link marketed this router as supporting DD-WRT. It contains an Emergency Recovery Mode, which allows easy switching between factory, DD-WRT and OpenWrt firmware. Although the last supported factory firmware update (v1.20b02) was released in October 2017, D-Link released a beta update (v1.21b03) in August 2018 to address the WPA2 KRACK vulnerability, and a subsequent beta update (also v1.21b03) in February 2020 to address a USB Shareport security issue.


FIXME Any text with a light background (like this one) provides instructions for creating the Details Page. When you have filled in correct/useful information (instead of any template that's there) remove the instructions, as well as the <WRAP> that encloses it.

D-Link DIR-885L


  1. This is an empty template that suggests the information that should be present on a well-constructed Device Page. This means, that you have to fill it with life and information.
  2. There are several “fixme” tags with text on a light background (like this text) throughout this template. As you fill in the page, remove those tags so that people can judge its completeness.
  3. When there are no more “fixme” tags left, delete this one too, along with the <WRAP> that encloses it.
  • Please include only model specific information, omit bla,bla and put everything generic into separate articles
  • If you have no time to write certain stuff, link to docs
  • base-system should lead the way, do not explain this again
  • DO NOT provide a complete howto here! Instead groom the general documentation.

The A1 hardware version of this router is supported by providing a prebuilt firmware image containing the WLAN driver for the Broadcom BCM4366B chip. However, by manually installing the WLAN driver for the Broadcom BCM4366C chip, the OpenWrt firmware will work with the A2 hardware version.

There is also a A2 version WLAN Hardware is BCM4366C

For A2 hardware revision routers, additional firmware for the BCM4366C radio needs to be manually installed for the wireless to work. One can retrieve the blob directly from the Linux kernel git repository. To install the firmware, it needs to be installed in /lib/firmware/brcm/.

FIXME Please add the installation procedure here.

Install brcmfmac4366c-pcie firmware:

opkg update; opkg install brcmfmac-firmware-4366c0-pcie

FIXME Find out flash layout, then add the flash layout table here (copy, paste, modify the example).

Please check out the article Flash layout. It contains examples and explanations that describe how to document the flash layout.

FIXME The instructions below are for Broadcom devices and only serve as an example.
Remove / modify them if they do not apply to this particular device!

This section deals with

  • How you install OpenWrt from a device freshly opened
  • The steps required such as reset to factory defaults if the device has already been configured

Note: Reset router to factory defaults if it has been previously configured.

  • Browse to
  • Upload .bin file to router
  • Wait for it to reboot
  • Telnet to and set a root password, or browse to if LuCI is installed.

D-Link Emergency Recovery Mode

Specific values needed for tftp

FIXME Enter values for “FILL-IN” below

Bootloader tftp server IPv4 address FILL-IN
Bootloader MAC address (special) FILL-IN
Firmware tftp image Latest OpenWrt release (NOTE: Name must contain “tftp”)
TFTP transfer window FILL-IN seconds
TFTP window start approximately FILL-IN seconds after power on
TFTP client required IP address FILL-IN


FIXME These are generic instructions. Update with your router's specifics.

  • Browse to LuCI Upgrade URL
  • Upload image file for sysupgrade to LuCI
  • Wait for reboot

If you don't have a GUI (LuCI) available, you can alternatively upgrade via the command line. There are two command line methods for upgrading:

  • sysupgrade
  • mtd

Note: It is important that you put the firmware image into the ramdisk (/tmp) before you start flashing.


  • Login as root via SSH on, then enter the following commands:
cd /tmp
wget http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc
sysupgrade /tmp/xxx.abc


If sysupgrade does not support this router, use mtd.

  • Login as root via SSH on, then enter the following commands:
cd /tmp
wget http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc
mtd write /tmp/xxx.abc linux && reboot

DIR-885L can be unbricked by D-Link Recovery mode:

  1. Reset to Factory from D-Link settings.
  2. Hold Reset button on power on for 10 seconds until flashing red light.
  3. Set static IP Address to and then visit and upload squash file.
  4. After login, immediately visit, and IMMEDIATELY go to backup / flash firmware, and reset to defaults.
  5. Then, afterwards go to system / backup flash firmware, and flash the firmware again. Untick the keep settings as well!

Basic configuration After flashing, proceed with this.
Set up your Internet connection, configure wireless, configure USB port, etc.

FIXME Please fill in real values for this device, then remove the EXAMPLEs

The default network configuration is:

Interface Name Description Default configuration
vlan0 (eth0.0) EXAMPLE LAN ports (1 to 4) EXAMPLE None
vlan1 (eth0.1) EXAMPLE WAN port EXAMPLE DHCP

FIXME Please fill in real values for this device, then remove the EXAMPLEs

Numbers 0-3 are Ports 1-4 as labeled on the unit, number 4 is the Internet (WAN) on the unit, 5 is the internal connection to the router itself. Don't be fooled: Port 1 on the unit is number 3 when configuring VLANs. vlan0 = eth0.0, vlan1 = eth0.1 and so on.
