Installation Instructions

Step-by-step instructions from out-of-the-box factory firmware

DD-WRT can be flashed directly on the D-Link DIR-868L by using the D-Link web interface:

  1. Navigate to this page, select year, scroll down to the last link and select it, select dlink-dir868l-revc. Now download the firmware file (dir868c-webflash.bin).
  2. Open the D-Link web-interface in your web browser (address:, Log In, and go to Tools -> Firmware *Warning: only flash over an Ethernet-cable
  3. Select factory-to-ddwrt.bin and click the "Upload"-button
  4. After flashing successfully, the router address should be changed into
  5. Upgrade the router (again) by using the dir-868-webflash.bin firmware
  • Note: The router doesn't support Hard Reset (aka 30/30/30 reset), use the Erasing NVRAM method instead.

How to restore to factory firmware

Also works if you bricked your router.

  1. Download the stock firmware at
  2. Set your computers IP manually to with a standard subnet of (like this on Windows).
  3. Unplug all cables (incl. power cable) from the router
  4. Insert a paper clip onto the hidden reset button located on the bottom of the device; you'll find it.
  5. Keep holding down the reset button as you plug in the power cable. Wait atleast 10 seconds until you release the paper clip.
  6. Connect your computer to the first LAN port.
  7. Navigate to and upload the firmware you downloaded earlier. The router will flash it and reboot automatically.
  8. Now set your computer IP to automaticly detect, navigate to your gateway and login.
  9. Navigate to Tools - System and Restore Factory Settings.

Known Issues

Bad WiFi drivers

DD-WRT has multiple issues with WiFi firmware.

  • WiFi connect slow: you might experience slowness connecting your device to the AP. On Android it always hangs at "Obtaining IP address" for ~10 seconds.
  • Link speed: the link speed on DD-WRT is not high as stock is. For example: DD-WRT has a link speed for 5GHz of 200Mbit/s, on stock it is 433Mbit/s. Same goes for the 2.4GHz band.
  • 5GHz band issue: the 5GHz band might not pop up when you search for WiFi networks on your device, it will take ~10 seconds to show up to even be able to connect to it.


If using the inbuilt OpenVPN-server in tunnel-mode, you may need to use the following firewall rules:

iptables -A INPUT -i vlan2 -m state --state NEW -p udp --dport 1194 -j ACCEPT
iptables -A INPUT -i tun2 -j ACCEPT
iptables -A FORWARD -i tun2 -j ACCEPT
iptables -A FORWARD -i tun2 -o vlan2 -m state --state RELATED,ESTABLISHED -j ACCEPT
iptables -A FORWARD -i vlan2 -o tun2 -m state --state RELATED,ESTABLISHED -j ACCEPT
iptables -t nat -A POSTROUTING -s -o vlan2 -j MASQUERADE
  • Note 1: Verify that the interfaces are correct by running the ifconfig command
  • Note 2: You may need to adjust the above IP-address (& netmask)

The following Additional DNSMasq Options may also be needed, to stop DHCP(-service) on the tunnel-port:



D-Link offers router owners a free dynamic DNS host name service. This service works (surprisingly) without any problems on the dd-wrt firmware:

DDNS Service DynDNS.org
Username Your username (no email-address)
Password Your Password
Hostname <hostname>.dlinkddns.com
Type Dynamic
IP Check Yes *only when needed

A working state should give verification messages, like this one:

Thu Jan 22 23:11:21 2015: INADYN: Started 'INADYN Advanced version 1.96-ADV' - dynamic DNS updater. 
Thu Jan 22 23:11:21 2015: INADYN: IP read from cache file is 'x.x.x.x'. No update required.
