Security
Note that all clients share the same keys, which are used for user authentication
and data encryption. Up to four keys can be specified. These four keys are used
for all VAP interfaces on the same radio.
To set up WEP shared keys, click Radio Settings under 802.11a or 802.11b/g, then
select Authentication ‘Shared’. To use all other than WEP shared keys, select
Authentication ‘Open.’
The following example presumes that you have selected to opt for other methods
of encryption than WEP.
Figure 40 Authentication and Encryption
Authentication – Sets the access point to communicate as an open system that
accepts network access attempts from any client, or with clients using
pre-configured static shared keys. (Default: Open System)
„
Open System: If you don’t set up any other security mechanism on the access
point, the network has no protection and is open to all users. This is the default
setting.
„
Shared Key: Sets the access point to use WEP shared keys. If this option is
selected, you must configure at least one key on the access point and all clients.
NOTE:
To use 802.1X on wireless clients requires a network card driver and
802.1X client software that supports the EAP authentication type that you want to
use. Windows 2000 SP3 or later and Windows XP provide 802.1X client support.
Windows XP also provides native WPA support. Other systems require additional
client software to support 802.1X and WPA.
