If you have a second client station, that station also needs to have one of the WEP keys
defined on the AP. You could give it the same WEP key you gave to the first station. Or
for a more secure solution, you could give the second station a different WEP key (key 2,
for example) so that the two stations cannot decrypt each other’s transmissions.
Static WEP with Transfer Key Indexes on Client Stations
Some Wireless client software (like Funk Odyssey) lets you configure multiple WEP keys
and set a transfer index on the client station, then you can specify different keys to be
used for station-to-AP transmissions. (The standard Windows wireless client software does
not allow you to do this.)
To build on our example, using Funk Odyssey client software you could give each of the
clients WEP key 3 so that they can decode the AP transmissions with that key and also
give client 1 WEP key 1 and set this as its transfer key. You could then give client 2 WEP
key 2 and set this as its transfer key index.
The following figure illustrates the dynamics of the AP and two client stations using
multiple WEP keys and a transfer key index.
IEEE 802.1x
IEEE 802.1x is a standard for network access control. It involves passing the Extensible
Authentication Protocol (EAP) over IEEE 802.11 LANs using a protocol called EAP
Encapsulation Over LANs (EAPOL).
This mode requires the use of a RADIUS server to authenticate users, and configuration
of user accounts through the
Cluster > User Management tab.
The access point requires a RADIUS server capable of EAP, such as the Microsoft Internet
Authentication Server or the Gateway 7001 Series self-managed AP internal authentication
server. To work with Windows clients, the authentication server must support Protected
EAP (PEAP) and MSCHAP V2.
