Section 3 - Configuration
Enable Hidden Wireless:
Check this box if you do not want the SSID of your wireless network to be broadcasted by the DAP-1155. If enabled, the SSID
of the DAP-1155 will not be seen by Site Survey utilities so your wireless clients will have to know the SSID of your DAP-1155
in order to connect to it.
Security Mode:
Refer to page 51 for more information regarding the wireless security.
