DD-WRT is a Linux-based firmware for wireless routers and wireless access points. It is compatible with several models of router and access point, most notably the Linksys WRT54G series (including the WRT54GL and WRT54GS). DD-WRT is among many third-party firmwares, which are designed to replace the firmware that ships pre-installed on many commercial routers. There are many advantages to running alternative firmware, including that it typically has features that the manufacturer's firmware does not.
DD-WRT includes such features as support for the Kai network, daemon-based services, IPv6, Wireless Distribution System, RADIUS, advanced quality of service, radio output power control, overclocking capability, and software support for a Secure Digital card hardware modification.
Buffalo Technology and other companies have shipped routers pre-installed with a customized version of DD-WRT.[3][4]

Version history [edit]
The first DD-WRT version, released 2005-01-22,[5] was called 16 and was created as a branch of Sveasoft Alchemy, which in turn is based on the Linksys WRT54G firmware.
DD-WRT version 22, released 2005-07-25,[6] was the last version to use the Alchemy kernel.
DD-WRT version 23, released 2005-12-25,[7] was the first version to use the OpenWrt kernel instead of the Alchemy kernel.
DD-WRT version 23 Service Pack 1 was released on 16 May 2006. Much of the code was overhauled and rewritten during the development of this release, and many new features were added.
DD-WRT version 23 Service Pack 2 was released on 14 September 2006. The interface was overhauled, and some new features were added. Some additional router models are supported, with more planned.
DD-WRT version 24 was released on 18 May 2008. It allows up to 16 virtual interfaces with different SSIDs and encryption protocols. It can run on some PowerPC, IXP425-based router boards, Atheros WiSOC, and X86-based systems. It can also run to some extent on routers with low flash memory (ex. WRT54Gv8 or WRT54GSv7).
DD-WRT version 24 Service Pack 1 was released on 26 July 2008. It contains an urgent DNS security fix for an issue in dnsmasq, site survey security fixes, longer passwords, and flexible OpenVPN configurations. It also can run on additional hardware, including WRT300 v1.1, WRT310N, WRT600N, Tonze AP42X Pronghorn SBC, Ubiquiti LSX and Netgear, Belkin, and USR devices.

Security issues [edit]
A remote command execution vulnerability in DD-WRT's HTTPd server was found by a Bulgarian hacker on 21 July 2009, and was patched within a few hours after being documented on milw0rm.[12] However, all prior DD-WRT versions (before build 12533 of v24 preSP2) remain vulnerable to this exploit.
