Recommended Action Re-enter the static WEP key, making sure to enter the correct number of characters and click OK.

Error Message ‘x’ contains characters which are non-hexadecimal.

Explanation One of the static WEP keys on the Define Pre-Shared Keys window contains non-hexadecimal characters even though Hexadecimal is specified as the Key Entry type.

Recommended Action Re-enter the static WEP key following the guidelines in the “Enabling Static WEP” section on page 5-24.

Error Message ‘x’ is not a hexadecimal character.

Explanation The character you entered on the Define Pre-Shared Keys window is not a hexadecimal character.

Recommended Action Re-enter the static WEP key following the guidelines in the “Enabling Static WEP” section on page 5-24.

Error Message You are not registered with the authentication server. A security credential is required to register this device. Do you want to obtain a security credential?

Explanation Automatic PAC provisioning is enabled for this profile. However, a valid PAC matching the server to which the client adapter is connecting could not be found.

Recommended Action Click Yes to provision a new PAC for this server using your existing credentials or click No to cancel the operation. If you click No, the client adapter is unable to authenticate using the existing profile.
