DD-WRT

DD-WRT is a Linux-based firmware for several wireless routers, most notably the Linksys WRT54G (including the WRT54GL and WRT54GS). Like other similar projects, DD-WRT is considered a third-party firmware solution designed to replace the firmware that ships pre-installed on many commercial routers. This is done for a variety of reasons including the addition of features which are not typically included in a manufacturer's router firmware.

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.

Code development

DD-WRT versions up to v22 were based on the Alchemy firmware from Sveasoft, which in turn is based on the original Linksys firmware. DD-WRT versions from v23 onwards, however, are almost completely rewritten. The Linux kernel part is based on the OpenWrt kernel, which started as Linksys-based firmware but was later changed to its own build framework. All of the firmware is based on Linux, as are OpenWrt and Alchemy.
