CHAPTER 4: SYSTEM CONFIGURATION
Error Messages – An example of a logged error message is: “Station Failed to
authenticate (unsupported algorithm).”
This message may be caused by any of the following conditions:
 Access point was set to “Open Authentication”, but a client sent an
authentication request frame with a “Shared key.”
 Access point was set to “Shared Key Authentication,” but a client sent an
authentication frame for “Open System.”
 WEP keys do not match: When the access point uses “Shared Key
Authentication,” but the key used by client and access point are not the same,
the frame will be decrypted incorrectly, using the wrong algorithm and
sequence number.
