DD-WRT - Definition from the Hotspot Shield Glossary

This is a firmware development based on the Linux OS that is used to improve the performance of wireless routers. DD-WRT is an open-source software, and using the software allows certain restrictions to be lifted on routers and provides access to advanced routing features.

This can mean an individual or organization can have more control over their wireless network and create a more versatile system. Traditionally, routers have been created for non-technical users so offer limited customization and functionality - DD-WRT intends to address this issue and allow wireless routers to be effectively used by large businesses and corporations. DD-WRT has been used since 2005, and is considered the premier firmware option for supporting routing.
