Showing Counters

Signal Retry Frames Sent (TxSingleRetryFrames)

This counter displays the number of messages that were retransmitted a single time before
being acknowledged by the receiving device. Retransmission is a normal behavior for the
IEEE 802.11 protocol in order to recover quickly from lost messages. A relatively high
value for this counter in comparison with the TxFragments counter identifies a wireless
network that suffers from interference (noise) or a heavy load of wireless data traffic.
See also TxMultipleRetryFrames.

Multiple Retry Frames Sent (TxMultipleRetryFrames)

This counter displays the number of messages that were retransmitted multiple times before
being acknowledged by the receiving device. Retransmission is a normal behavior for the
IEEE 802.11 protocol in order to recover quickly from lost messages. A relatively high
value for this counter in comparison with the TxFragments counter identifies a wireless
network that suffers from interference (noise) or a heavy load of wireless data traffic.
High values for this counter result in lower throughput for the PC Card as the system falls
back to the next lower transmit rate when more than one retransmission retry is needed to
transfer a message.
See also TxSingleRetryFrames.

Transmit Retry Limit Exceeded Frames (TxRetryLimitExceeded)

This counter displays the number of messages that could not be delivered after the
maximum number of retransmissions. You can use this counter together with TxDiscards
to identify a wireless network that is overloaded due to severe interference or excessive
load of wireless data traffic. The system drops such messages and depends on the higher
communication protocols to recover from this lost message.

Transmit Frames Discarded (TxDiscards)

This counter displays the number messages that could not be transmitted due to congestion
at the RoamAbout PC Card. In normal situations, the PC Card can temporarily store
messages that are to be transmitted in an internal buffer. When this buffer is full, the PC
Card discards any new messages until buffer space becomes available again. When this
counter is relatively high, this may identify a wireless network with a heavy load of wireless
data traffic.
