With a closed network, the wireless network (SSID) will not broadcast. Users are required to type the SSID into the client application, instead of selecting the SSID from the wireless network available list. By default, the SSID is set to broadcast and it can be detected by the wireless clients. This document describes how to disable the 2.4 GHz wireless network (SSID) from broadcasting.
CAUTION: In order to configure the SBG6400Â to not broadcast the wireless network (SSID), the Automatic Security Configuration (WPS)Â feature must be disabled.Â
To Configure Closed System Network
