The manufacturer of a SOHO router has released a security fix for the router. Which of the following methods should be used to apply the fix?

Changing the admin password is a good security practice but does not apply a manufacturer-released security patch to the router's underlying software.

Applying a new WEP key is a Wi-Fi security setting change, and WEP itself is an outdated and insecure protocol; it does not apply a general security fix for the router's firmware.

Router security fixes are almost always implemented through firmware updates, which involve replacing the device's operating software with a new version containing patches for known vulnerabilities. Manufacturers release new firmware versions to address security flaws and improve device stability.

Holding the reset button restores the router to its factory default settings, which might remove custom configurations but does not update the firmware or apply security patches.
