The Aironet Client Utility is used to perform user level diagnostics on the
Cisco Wireless LAN Adapter Card. It allows firmware upgrade, viewing current
device status, as well as viewing the current device statistics. These tools
are readily available from the icons located at the top portion of the ACU main
screen
. A linktest can
be performed to assess the performance of the RF link at various places in the
area. The results of the linktest can be used to determine the RF Network
coverage, which can be used to figure out the required number and placement of
APs. Link test results help to eliminate dead spots where low RF signal levels
may cause the loss of connection between the Cisco Wireless LAN Adapter Card
and the AP. Low RF signals may be due to either the RF signal being attenuated
by the environment or from multipath interference.
