● Signal strength [%]
Shows the signal strength of the access point as a percentage.
● Type
Shows the mode of the WLAN interface.
● Security
Shows which authentication method is used.
If the authentication method "Open Encryption" or "Shared Key" is used,
"Encrypted (WEP/AES)" is displayed for both authentication methods.
● WLAN Mode
Shows the transmission standard. If DFS is activated, the transmission standard "802.11h"
is not shown additionally but only the configured transmission standard "802.11a" or
"802.11n".
● State
Shows the status of the access point, for example whether or not the access point is
available.

IP Mapping Table
WLAN access for several SCALANCE W devices via one client
Note
This WBM page is only available for clients or access points in client mode.
You can make WLAN access available for several SCALANCE W devices with one client if you
use IP mapping. This means that you do not need to equip every SCALANCE W device with its
own WLAN client. The prerequisite for this is that the connected SCALANCE W devices are
addressed only with IP frames. Communication at MAC address level (ISO/OSI layer 2) can
● be established with one component whose MAC address is configured on the client,
● be established with a maximum of eight components if the "Layer 2 Tunnel" function is
selected.
The "Layer 2 Tunnel" setting meets the requirements of industrial applications in which MAC
address-based communication takes place with several SCALANCE W devices downstream
from the client. Clients with this setting cannot connect on standard Wifi access points.
The client maintains a table with the assignment of MAC address and IP address to send
incoming IP frames to the correct MAC address. This WBM page shows this table.
Note
IP mapping table
If "Layer 2 Tunnel" is configured for a client, the IP mapping table is not displayed.
