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 access point, WLAN clients that use an empty SSID or the SSID "ANY" are prevented from associating with your network.
The option SSID broadcast provides the following settings:
- Yes: The access point broadcasts the radio cell's SSID. When a client sends a probe request with an empty or incorrect SSID, the access point responds with the SSID of the radio cell (publicly visible WLAN).
- No: The access point does not broadcast the radio cell's SSID. When a client sends a probe request with an empty SSID, the access point similarly responds with an empty SSID.
- Tightened: The access point does not broadcast the radio cell's SSID. When a client sends a probe request with an empty or incorrect SSID, the access point does not respond.
Note: Simply suppressing the SSID broadcast does not provide adequate protection: When legitimate WLAN clients associate with the access point, this transmits the SSID in plain text so that it is briefly visible to all clients in the WLAN network.
Note: The "closed network" function for the access point is to be found under . Please note: If the WLAN controller has the option SSID broadcast set to "No" (device does not broadcast the SSID), the access point sets its closed network option to "Yes", and vice versa. Only with the setting "Tightened" do both devices retain identical settings.
