Routers are basically little computers. By default, they run a manufacture-provided operating system, or firmware, to route network traffic and provide you with various settings and features. But you can often replace this firmware.

Most people don’t need a third-party custom router firmware. Yes, custom firmware can provide you with additional features and other benefits, but they’re more complex and most people just want their router to function as an appliance.
