Viewing Statistics for Your Client Adapter
Table 7-4 describes each statistic that is displayed for your client adapter.
Table 7-4 Client Adapter Statistics
Statistic Description
Receive Statistics
Multicast Packets Received The number of multicast packets that were received successfully.
Broadcast Packets Received The number of broadcast packets that were received successfully.
Unicast Packets Received The number of unicast packets that were received successfully.
Bytes Received The number of bytes of data that were received successfully.
Beacons Received The number of beacon packets that were received successfully.
Total Packets Received OK The number of all packets that were received successfully.
Duplicate Packets Received The number of duplicate packets that were received successfully.
Overrun Errors The number of packets received when no receive buffers were
available. These errors usually occur when the host does not read
the received packets from the client adapter fast enough.
PLCP CRC Errors The number of times the client adapter started to receive an
802.11 physical layer convergence protocol (PLCP) header but
the rest of the packet was ignored due to a cyclic redundancy
check (CRC) error in the header.
Note CRC errors can be attributed to packet collisions caused
by a dense population of client adapters, overlapping
access point coverage on a channel, high multipath
conditions due to bounced signals, or the presence of
other 2.4-GHz signals from devices such as microwave
ovens, wireless handset phones, etc.
PLCP Format Errors The number of times an 802.11 PLCP header was received with a
valid CRC but the rest of the packet was ignored due to an
unknown value in the header.
PLCP Length Errors The number of times an 802.11 PLCP header was received but the
rest of the packet was ignored due to an illegal header length.
MAC CRC Errors The number of packets that had a valid 802.11 PLCP header but
contained a CRC error in the data portion of the packet.
Note CRC errors can be attributed to packet collisions caused
by a dense population of client adapters, overlapping
access point coverage on a channel, high multipath
conditions due to bounced signals, or the presence of
other 2.4-GHz signals from devices such as microwave
ovens, wireless handset phones, etc.
Partial Packets Received The number of fragments that were discarded because the entire
packet was not received successfully.
SSID Mismatches The number of times the client adapter tried to associate to an
access point but was unable to because the adapter’s SSID was not
the same as the access point’s.
