Cisco ADU: Other Tools—Diagnostic (Cont.)In the client managed test, thenetwork connectivity is tested fromthe WLAN adapter, starting fromthe driver installation up to network and authentication test, and through card insertion, enable,radio and association tests.
There is also a networkmanaged test, where the testis conducted from the WLC,
the client being passive. Thistests how the networks sees

Cisco Aironet Site Survey Utility
Action / options
The utility gives you dynamic representation of your connectionto the wireless network.It displays AP MAC address, channel,RSSI, noise level, SNR, speed ofyour connection.From this the connection quality is shown (green/excellent, yellow/good,orange/fair, red/poor).
From Action>Enable Proximity Beeper, get adetection beep when getting closer to the AP.From Action>Option, select what triggers the
proximity beeper.

Cisco Aironet Site Survey Utility: Thresholds
From Threshold>Configure Thresholds, determine how you
want to log events detected by the utility. They can be changes in the association, connection (or loss) to
an URL, RSSI, noise, SNR, or speed thresholds. This allows you
to determine physical limits of your cells. To avoid too many entries in
the logs, you can configure the minimum duration of an event
worth noticing.

Cisco Aironet Site Survey Utility: AP Scan List
The AP scan list reports all the APs detected by your adapter, not for you to pick one to associate to, but to analyze the APs around the adapters and determine their physical characteristics.
You can interrupt the scanning process to stay on one channel, log the list.
Accumulate writes all the detected APs over time, without deleting those not in
range anymore.

Click AP Scanning>Configure to determine how often the AP list would
be logged automatically, and/or in which case a log entry should be
written.

Cisco Aironet Configuration Administration Utility
ADU behaviour Profiles creation
The ACAU allows the network administrator to centrally create profiles to be deployed to clients’ ADUs, and to configure how the ADU should be installed and configured in automated deployments(global settings)

Cisco Aironet Configuration Administration Utility: Profile Management
Creating a profile from the ACAU isvery similar to the same process on
the ADU, general, security, advancedtabs are the same.
