OEM easy installation
OpenWrt can be installed via D-Link Recovery GUI:
- Power down the router, press and hold the reset button, then re-plug it, still keeping the reset button pressed.
- Keep the reset button pressed until the power LED starts flashing orange
- Manually assign a static IP address under the 192.168.0.xxx subnet (e.g. 192.168.0.2) and go to http://192.168.0.1
- Select the Factory firmware (the file with the suffix recovery.bin) and flash it
Apparently there is a buggy connection with some Linux-Computers, with Windows and Firefox it should work. Some modern browsers may have problems flashing via the Recovery GUI. If that occurs consider uploading the firmware through cURL:
curl -v -i -F "firmware=@file.bin" 192.168.0.1
OEM installation using the TFTP method

Upgrading OpenWrt
These are generic instructions. Update with your router's specifics.
LuCI Web Upgrade Process
- Browse to
http://192.168.1.1/cgi-bin/luci/mini/system/upgrade/LuCI Upgrade URL - Upload image file for sysupgrade to LuCI
- Wait for reboot
Terminal Upgrade Process
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:
sysupgrademtd
Note: It is important that you put the firmware image into the ramdisk (/tmp) before you start flashing.
sysupgrade
- Login as root via SSH on 192.168.1.1, then enter the following commands:
cd /tmp wget http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc sysupgrade /tmp/xxx.abc
mtd
If sysupgrade does not support this router, use mtd.
- Login as root via SSH on 192.168.1.1, then enter the following commands:
cd /tmp wget http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc mtd write /tmp/xxx.abc linux && reboot

Network interfaces
The default network configuration is:
| Interface Name | Description | Default configuration |
|---|---|---|
| br-lan | EXAMPLE LAN & WiFi | EXAMPLE 192.168.1.1/24 |
| vlan0 (eth0.0) | EXAMPLE LAN ports (1 to 4) | EXAMPLE None |
| vlan1 (eth0.1) | EXAMPLE WAN port | EXAMPLE DHCP |
| wl0 | EXAMPLE WiFi | EXAMPLE Disabled |
Switch Ports (for VLANs)
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.
| Port | Switch port |
|---|---|
| Internet (WAN) | EXAMPLE 4 |
| LAN 1 | EXAMPLE 3 |
| LAN 2 | EXAMPLE 2 |
| LAN 3 | EXAMPLE 1 |
| LAN 4 | EXAMPLE 0 |
