The firmware on your D-Link router is stored on a built-in flash chip and is responsible for the functionality of your device. The firmware supplies the information your computer and networked devices uses for operability and communication. Elements such as the onscreen configuration panel and port forwarding instructions all rely on the device's firmware. D-Link occasionally may provide an update for your device. Updates are usually released to improve features and patch any bugs that were not accounted for during development. You can perform a firmware upgrade within the router's configuration page.
