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.
