Which RouterOS software packages are required to configure a wireless AP?

To configure a wireless Access Point (AP) in MikroTik RouterOS, the required software package is the Wireless package. This package specifically provides the necessary drivers and functionality to manage and configure the wireless interfaces on the router, allowing them to operate as an AP.

The System package is indeed necessary for the overall operation of RouterOS, as it contains the core functionality and interfaces. However, it does not include the specific tools required to manage wireless features. As such, while the System package is essential for the router to operate, it is the Wireless package that directly enables the configuration and management of wireless access points.

The advanced-tools package provides additional utilities and features for managing the router but is not a prerequisite for configuring a wireless AP. Similarly, the routing package includes tools for dynamic routing protocols and managing the router’s routing tables, which are not specifically needed for wireless AP configuration.

Thus, to effectively set up and manage a wireless AP, it's critical to have the Wireless package included in the RouterOS installation.
