Common mistakes.

A. Physically securing the router prevents unauthorized physical access but does not control incoming network traffic ports.
B. Implementing AES encryption is for securing wireless data transmission, not for controlling which incoming ports are allowed on the router's firewall.
C. Installing the latest firmware is a general security best practice that can fix vulnerabilities, but it doesn't specifically control incoming port allowances as directly as disabling UPnP or configuring firewall rules.
