WARNING
Be sure to eliminate loops from networks that consist of wireless bridges, Ethernet switches,
Ethernet links, and WDS links. If any loops exist, packets will circle around the loops and
network performance will be seriously degraded.

Security
IEEE 802.11g security settings include SSID broadcasts, Wireless client isolation, Security
mode, IEEE 802.11 Authentication algorithm, WEP keys, MAC-Address-Based Access
Control.
Basic
For security reasons, it is highly recommended that you do not set the security mode to the Open
System option. When the security mode is set to Open System, no authentication or data
encryption will be performed. In addition, you can disable the SSID broadcast functionality so that
a wireless client computer with an SSID set to “any” cannot associate with the NI
WAP-3701/3711.
When the Wireless client isolation setting is set to This AP Only, wireless clients of this AP
cannot see each other, and wireless-to-wireless traffic is blocked. When the setting is set to All
APs in this Subnet, traffic between wireless users from different APs on 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. The behaviors are illustrated in the following
figures.
