Refer to the exhibit. Clients report that they cannot connect to this SSID using the provided PSK. Which action will resolve this issue?

An incorrect interface would prevent the WLAN from being broadcast or having connectivity, but the specific issue described is PSK authentication failure, not a general lack of connectivity.

Applying changes is a general step to save configurations, but it does not address the root cause of the PSK not being selected in the first place.

The exhibit likely shows that the Pre-Shared Key (PSK) is not properly selected or enabled under the authentication key management settings for the WLAN, preventing clients from authenticating successfully. Selecting the PSK under authentication key management ensures that the WLAN uses the configured PSK for client authentication, resolving the connection issue.

Radio Policy defines radio settings such as bands and data rates, but it does not directly control PSK authentication settings.
