Definition: DD-WRT

(DresDen-Wireless RouTer) A Linux-based open-source operating system that is available as a firmware upgrade for many wireless routers, and some routers come with DD-WRT pre-installed. Often used to give a performance boost to older routers, in addition to normal router configuration, DD-WRT serves as a network monitoring tool and a scheduler (see cron). It can also reboot the router if access to the Internet slows and even overclock the router for gamers.

Developed in 2005, DD-WRT was based on firmware in the Linksys WRT54G router. It then became an open-source project developed and maintained by Sebastian Gottschall (a.k.a BrainSlayer). Gottschall lives in Dresden, Germany, which uses "DD" as a prefix on its vehicle license plates. See OpenWrt and HyperWRT.
