You can operate your wireless LAN either in public or private mode. A wireless LAN in public mode can be contacted by any mobile station in the area. Your wireless LAN is put into private mode by activating the closed network function. In this operation mode, mobile stations that do not know the network name (SSID) are excluded from taking part in the wireless LAN.
With the closed-network mode activated on the AP, WLAN clients that use an empty SSID or the SSID "ANY" are prevented from associating with your network.
Note: Simply suppressing the SSID broadcast does not provide adequate protection: When legitimate WLAN clients associate with the AP, this transmits the SSID in cleartext so that it is briefly visible to all clients in the WLAN network.
Note: The "closed network" function for the AP is to be found under . Please note: If the WLC has the option SSID broadcast set to "No" (device does not broadcast the SSID), the AP sets its closed network option to "Yes", and vice versa. Only with the setting "Tightened" do both devices retain identical settings.

- Console path:
- Setup > WLAN-Management > AP-Configuration > Networkprofiles
- Possible values:
- No
- The AP does not publish the SSID of the cell. When a client sends a probe request with an empty SSID, the AP similarly responds with an empty SSID.
- Yes
- The AP publishes the SSID of the cell. When a client sends a probe request with an empty or incorrect SSID, the AP responds with the SSID of the radio cell (publicly visible WLAN).
- Tightened
- The AP does not publish the SSID of the cell. When a client sends a probe request with a blank or incorrect SSID, the AP does not respond.
- Default:
- Yes
