To configure a wireless access point in RouterOS, which software package is essential?

Configuring a wireless access point in RouterOS requires the Wireless software package because it contains the necessary components and features specifically designed for managing wireless interfaces. This package provides the tools needed to set up, secure, and optimize wireless networks, including the ability to configure SSIDs, security protocols, and frequencies.

While other packages like DHCP and routing play important roles in network management, they do not specifically address the configurations needed for wireless access points. The advanced-tools package provides additional utilities but is not essential for basic wireless access point configurations. Therefore, the Wireless package is key to enabling and managing wireless functionality effectively in RouterOS.
