Wireless Settings
The essential settings for wireless networks are presented in this function group. Settings must be properly set
before establishing your wireless network. Familiarize yourself with the following terms before starting the
configuration process:
AP: In a wireless local area network (WLAN), an access point is a station that transmits and receives data.
Client: When the TAP-125-U-W-X-Z (YYYYYYYY) is configured for Client mode, it can be used as an
Ethernet-to-wireless (or LAN-to-WLAN) network adaptor. For example, a notebook computer equipped with an
Ethernet adaptor but no wireless card can be connected to this device with an Ethernet cable to provide
wireless connectivity to another AP.

Basic Wireless Settings
The “WLAN Basic Setting Selection” panel is used to add and edit SSIDs. An SSID is a unique identifier that
wireless networking devices use to establish and maintain wireless connectivity. Multiple access points on a
network or sub-network can use the same SSIDs. You can configure your TAP to use up to 9 SSIDs, and
configure each SSID differently. All of the SSIDs are active at the same time; that is, client devices can use any
of the SSIDs to associate with the access point.
Click on Add SSID to create more SSIDs.
Click on Edit to assign different configuration settings to each SSID. The configuration panel appears as
follows:

Client Isolation (for AP mode only)
Client isolation is used to isolate the associated wireless clients in one or more APs. Isolated clients cannot
communicate with each other, so the level of security is increased. Depending on the type of client isolation,
you may also define the exception clients inside the isolation network. It can be used in server access.
Client Isolation
Setting
Description
Factory Default
No isolation
No isolation is applied.
No isolation
Isolated within the
same VAP
All clients associated to this Virtual AP (VAP) will be isolated
from each other.
Isolated within the
same subnet
All clients in the specified subnet will be isolated from each
other. The subnet is defined by the following two parameters,
gateway and netmask.
