Linux-based firmware for wireless routers and wireless access points From Wikipedia, the free encyclopedia
DD-WRT is Linux-based firmware for wireless routers and access points. Originally designed for the Linksys WRT54G series, it now runs on a wide variety of models. DD-WRT is one of a handful of third-party firmware projects designed to replace manufacturer's original firmware with custom firmware offering additional features or functionality.

Sebastian Gottschall, a.k.a. "BrainSlayer", is the founder and primary maintainer of the DD-WRT project.[3] The letters "DD" in the project name are the German license-plate letters for vehicles from Dresden, where the development team lived.[4] The remainder of the name was taken from the Linksys WRT54G model router, a home router popular in 2002–2004. WRT is assumed to be a reference to 'wireless router'.
Buffalo Technology and other companies have shipped routers with factory-installed, customized versions of DD-WRT.[5][6] In January 2016, Linksys started to offer DD-WRT firmware for their routers.[7]

| Version | Release date | Changes | Refs |
|---|---|---|---|
| 16 | 22 January 2005 | Initial release. Created as a branch of Sveasoft Alchemy, which, in turn, is based on the Linksys WRT54G firmware | [14] |
| 22 | 25 July 2005 | ? | |
| 23 | 25 December 2005 | Replaced the Alchemy kernel with the OpenWrt kernel | |
| 23 SP 1 | 16 May 2006 | In this service pack, much of the code was overhauled and rewritten during the development of this release; many new features were added. | |
| 23 SP 2 | 14 September 2006 | The interface was overhauled, and some new features were added. Some additional router models are supported. | |
| 24 | 18 May 2008 | 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) | |
| 24 SP 1 | 26 July 2008 | Critical DNS security fix for an issue in dnsmasq, site survey security fixes, longer passwords, and flexible OpenVPN configurations. It can also run on additional hardware, including WRT300 v1.1, WRT310N, WRT600N, Tonze AP42X Pronghorn SBC, Ubiquiti LSX and Netgear, Belkin, and USR devices. | |
| 3.0 beta | rolling | Since 2010, the DD-WRT developers have frequently published beta builds for various routers. In January 2018 WireGuard was made available for routers with 8 MB or more flash and has been updated regularly by BrainSlayer. Due to inevitable security improvements in the Linux kernel and other packages, over such a long time, the 3.0 beta releases are now considered more stable than 24SP1 version. [15] | [16] |
DD-WRT supports many different router models, both new and obsolete. The project maintains a full list of currently supported models[17] and known incompatible devices.[18]
