Caveats

This section describes resolved problems for client adapter firmware release 4.23.

Resolved Caveats

When a client adapter with LEAP, WEP, and mixed-cell support enabled associates to an access point that has EAP and mixed WEP enabled, the client authenticates successfully but is unable to receive broadcasts from the access point (CSCdt38879).

The most notable symptom is the inability of the client to receive a DHCP-assigned IP address. If the client is assigned a static IP address, it is able to successfully send and receive directed traffic. If the client associates to the same access point with WEP disabled, it can receive both broadcast and directed traffic.

Getting Bug Information on Cisco.com
