IEEE 802.11 Authentication algorithm, WEP, WPA, and MAC-Address-Based
Access Control.

For security reasons, it's highly recommended that the security mode be set
to options other than Open System. When the security mode is set to Open
System, no authentication and data encryption will be performed.
You can disable the SSID broadcasts functionality so that a wireless client
(STA or AP) with an “ANY” SSID cannot associate with the SMCWHSG44-G.
With this feature enabled any wireless user can see your wireless LAN and
connect to it with an SSID of “ANY”.
Wireless Client Isolation is a feature for the SMCWHSG44-G to block wireless-to-
wireless traffic between STAs so that the STAs cannot see each other. This
feature is useful for WLANs deployed in public places. This way, hackers have
no chance to attack other wireless users in a Hotspot.
When the Wireless client isolation setting is set to This AP Only, wireless
clients (STAs) associated to this SMCWHSG44-G, which acts as an AP, cannot see
each other, and wireless-to-wireless traffic between the STAs is blocked.
