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:
- 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
- Select factory-to-ddwrt.bin and click the "Upload"-button
- After flashing successfully, the router address should be changed into http://192.168.1.1
- 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.
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 |
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.
