What does the 'Connect' button do in RouterOS when configuring wireless?

The 'Connect' button in RouterOS, when configuring the wireless settings, serves the purpose of establishing a wireless connection to a specified SSID. This means that once you have selected a wireless network (SSID) and entered any necessary credentials, pressing the 'Connect' button initiates the process to associate the router with that particular wireless network.

This action is essential during the configuration phase, as it allows the router to join the desired wireless network, enabling it to communicate over that network. The successful connection to an SSID is a critical step, especially for routers operating in environments where multiple wireless networks are available, and it ensures that the device can access and transmit data over the selected network effectively.

The other options do not accurately reflect the function of the 'Connect' button. For instance, connecting to the internet generally involves various configurations beyond just pressing 'Connect', such as ensuring that appropriate WAN settings are properly set, and it can involve several protocols and layers, which the button itself does not handle directly.
