Fig. 43: Basic IEEE 802.11g security settings 

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. Additionally, you can disable the SSID broadcasts functionality so that a wireless 
client computer with an “any” SSID cannot associate with the AP. 

When the Wireless client isolation setting is set to This AP Only, wireless clients of this IEEE 
802.11b/g cannot see each other, and wireless-to-wireless traffic is blocked. When the setting is set to 
All APs in This Subnet, traffic among wireless users of different IEEE 802.11b/g’s in the same IP 
subnet is blocked. This feature is useful for WLANs deployed in public places. In 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) of this 
IEEE 802.11b/g cannot see each other, and wireless-to-wireless traffic between the STAs is blocked. 
When the setting is set to All APs in This Subnet, traffic among wireless users of different IEEE 
802.11b/g’s in the same IP subnet is blocked. The behaviors are illustrated in the following figures.
