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).

Open the D-Link web-interface in your web browser (address: http://192.168.0.1), Log In, and go to
Tools -> Firmware *Warning: only flash over an Ethernet-cable
2.
Select factory-to-ddwrt.bin and click the "Upload"-button3. After flashing successfully, the router address should be changed into http://192.168.1.14. Upgrade the router (again) by using the dir-868-webflash.bin firmware5.

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.
•
OpenVPN
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 10.8.0.0/24 -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:
interface=tun2
no-dhcp-interface=tun2
D-Link DDNS
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
D-Link_DIR-868L
Known Issues 3
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.
