7-18 Problem Solving
Receive Buffer Not Available (RxDiscardsNoBuffer)
This counter displays the number of times an incoming message could not be received due
to a shortage of receive buffers on the RoamAbout PC Card. A non-zero value identifies
heavy data traffic for your RoamAbout PC Card; for example, when your PC Card is
receiving large amounts of data.
Wrong Station Address on Transmit (TxDiscardsWrongSA)
This counter displays the number of times a message transmission was not done because a
wrong MAC address was used by the protocol stack. A non-zero value indicates an error
situation in the communication between your driver and the protocol stack.
Receive WEP Errors (RxDiscardsWEPUndecryptable)
This counter displays the number of times a received message was discarded because it
could not be decrypted by your PC Card. This means that:
• Both devices have enabled encryption, but use keys that do not match.
• One of the devices does not support encryption or does not have encryption enabled.
Use RoamAbout Client Utility Link Test, Configuration Info tab, to see the configuration
of the client and the Access Point or other client.
Receive Message in Message Fragments
(RxMessageInMsgFragments)
This counter displays the number of times messages were received while another
transmission was in progress. It is a measure of the amount of overlapped communication
in your system. Zero values indicate low to moderate load of your network. Non-zero
values identify a wireless medium that is being used simultaneously by multiple users.
Receive Message in Bad Message Fragments
(RxMessageInBadMsgFragments)
This counter displays the number of times messages were received while a transmission
elsewhere in the wireless network was in progress. This counter is expected to be zero.
Non-zero-values indicate a heavily loaded system.
WEP ICV Error
This counter increments when encrypted data has an error that prevents it from being
deciphered. A high number indicates a mismatched encryption key. A low number can be
caused by drop bits which can be ignored.
