Which of the following explains why the default administrator password for a home wireless router should be changed?

Default administrator passwords for routers are often publicly known or easily guessed, making devices vulnerable to unauthorized access. By changing this password, administrators secure the router's management interface, preventing malicious actors from making unauthorized configuration changes that could compromise network security.

Changing the administrator password does not prevent or enable data transmission encryption; encryption is a separate security setting configured within the router's wireless settings.

The administrator password has no direct impact on the physical wireless signal strength or range of the router.

While strong passwords contribute to overall security, changing a default password directly addresses technical unauthorized access to the device rather than the psychological manipulation involved in social engineering attacks.
