Which password should be changed first when configuring a wireless network?

When configuring a wireless network, changing the admin password first is crucial for ensuring the security of the network. The admin password provides access to the wireless router or access point's configuration settings. If this password is not changed from the default, unauthorized users may easily access the device and modify the settings, including changing the network name, encryption key, or other critical configurations. This could lead to vulnerabilities such as unauthorized access to the network, which can compromise data security and privacy.

Changing the admin password helps establish a secure foundation for the network by preventing unauthorized configuration changes. Once the admin password is secure, subsequent steps like modifying the encryption key and network name can enhance the overall security but will not be effective without first protecting the router or access point itself.
