Security for your WLAN
The security of wireless data also can be guaranteed using various tech-
niques:
Station filter
Using a closed network
Data encryption
You can also call up the wizards provided in WEBconfig or LANconfig to con-
figure the basic security settings.
Station filter
When defining an access list, specify which clients are allowed access to the
access point. Under the
/Setup/WLAN-module/Access-list
menu item, add the MAC addresses of the card whose access is to be moni-

/Setup/WLAN-mod-
ule/Access-mode
, you can define whether whether clients with these
card addresses have access (positive) or are not authorized (negative).
Closed network
On a closed network, the network name is not visible on remote stations.
Logging on using the 'ANY' network name is not possible in this case. There-
fore, all wireless stations on a closed network have to know the network
names and have them entered in their current user profiles.
Use the
/Setup/WLAN-module
menu to set the value for a closed net-
work to 'On' (no access with 'ANY') or 'Off' (access with 'ANY' allowed).
Data encryption
The
11-Mbit wireless
network cards support a data encryption based on the
WEP method (
W
ired
E
quivalent
P
rivacy). The 'Security' tab in the
AirLancer
Client Manager
lets you define four different keys, based on how
the data received and sent via wireless cards is decoded and
the data sent via wireless cards is encoded.
The four various keys can contain five alphanumeric characters from the
range 'a-z' and '0-9', whereby capitalization and lower case letters are distin-
