DD-WRT is a Linux-based open source firmware for a wide variety of wireless routers. This firmware supports hundreds of devices from dozens of vendors. For many devices, DD-WRT provides updates after the original, vendor-supplied firmware ceases to receive such updates. Often, DD-WRT also includes features not present in the vendor-supplied firmware. Some examples of features include: traffic shaping to prioritize certain types of data, transmission power control, SNMP monitoring, and virtual private networking using either OpenVPN or WireGuard. Users can determine if their hardware is supported with the Router Database. Any special notes for specific hardware will also be located there. Those uninterested in flashing the firmware on their existing router can also purchase routers with DD-WRT preinstalled from the Shop section of the DD-WRT website.
