A user is configuring a SOHO wireless router. The user should change the router's default administrator password for which of the following reasons?

Improper data transmission encryption is typically prevented by configuring strong encryption protocols (like WPA3) for the wireless network itself, not by changing the admin password.

Default administrator passwords are widely known or easily guessable, making routers vulnerable to unauthorized access. Changing the password ensures that only authorized individuals can log in and modify the router's settings, protecting network security.

While part of overall security, changing the admin password directly prevents unauthorized technical access to the router's configuration interface, not primarily social engineering attacks, which exploit human trust.

Changing the administrator password has no impact on the physical or logical signal strength of the wireless network.
