4.1.3 Computer Resource Requirements

WPA-PSK

In order to function properly, an Access Point that supports WPA-PSK must be available. The

WPA-PSK passphrase installed on the Access Point must match the passphrase configured on

the WLN.

LEAP

In order to function properly, a RADIUS server configured for LEAP containing

usernames/passwords, and an Access Point that supports LEAP, must be available. The

RADIUS server username and password must match the user-leap and pw-leap command

values configured on the WLN.

4.1.4 System Implementation Considerations

The WLN must be in infrastructure mode for WPA-PSK or LEAP to operate properly. A WLN

configured for WPA-PSK requires a connection to an AP with WPA-PSK enabled. A WLN

configured for LEAP requires a connection to an AP with LEAP enabled and connected to a

RADIUS server to provide authentication.

Until the WLN is authenticated by either the WPA-PSK enabled AP or the RADIUS server, no IP

network communication can proceed.

Symptoms of an unauthenticated client include:

 A WLN with serial-default set to “PASS” will not connect to the network client.

 A WLN configured for DHCP will not obtain host configuration from the DHCP server;

therefore, the IP address will remain 0.0.0.0.

 The Link LED turns on when 802.11 association completes. However, if the 802.1X

authentication fails, the WLN becomes disassociated by the AP and the Link LED turns

off. In effect, the Link LED will blink slowly as the process repeats.

 The WLN will not respond to discovery requests.
