Look at the status message at the bottom of the ACU screen and see if it displays the associated AP's MAC instead of its IP address. If so, you probably have mismatched WEP keys. By default, most 802.11b gear uses Open Authentication. Open Authentication allows a client to associate even if the WEP keys are different. Even though it associates, data packets (such as DHCP requests and responses) will not be encrypted/decrypted properly.
i want to add bit more information to this and that is check the page of AP and click on the link of the client on the main page and if it is showing Assoc and then u r unable to get the IP then there is a problem with Key missmatch an also check there should be no check mark under the open authentication i.e; in require EAP.
