DD-WRT is an alternative firmware for the Linksys WRT54G/GS/GL and the Asus WL-500 deluxe 802.11g wireless routers.

DD-WRT was originally based on the Alchemy Firmware from Sveasoft Inc., which is in turn based on the original GPL'd Linksys Firmware and a number of other open source projects.

It offers many advanced features not found in the original Linksys firmware, or even the firmware available for purchase from Sveasoft. It is also free of the product activation or tracking found in the Sveasoft firmware.
