Chapter 8 Using the Aironet Client Monitor (ACM)
Pop-Up Menu
This screen enables you to determine when ACM runs and to select the options that appear on the ACM
pop-up menu. The selections you make apply to every instance of ACM. For example, if you deselect
the Troubleshooting option, it will not appear in the pop-up menu for any ACM icon.
Follow the steps below to make your selections.
Step 1
If you want ACM to run automatically when Windows starts, make sure the Run the program
automatically when Windows starts check box is checked. Otherwise, uncheck this check box.
Note
If you do not select this option and later want to run ACM, you must use Windows Explorer to
find the path where the ACM software is installed. (The default location is C:\Program
Files\Cisco Systems\Aironet Client Monitor.) Then double-click ACUMon.exe.
Step 2
In the Menu Options portion of the screen, make sure the check boxes of all the options that you want
to appear in the ACM pop-up menu are checked. Any options that are not checked will not be included
in the menu.
Note
The Preferences option cannot be deselected. It always appears in the ACM pop-up menu.
Step 3
Click OK to save your changes.
Turn Radio On/Off
This option enables you to turn the client adapter’s radio on or off. Turning the radio off prevents the
adapter from transmitting RF energy. You might want to turn off the client adapter’s radio in the
following situations:
•
You are not transmitting data and want to conserve battery power.
•
You have EAP-SIM authentication set up to occur transparently (the SIM card is left in the reader
and the PIN is stored in the computer), and you do not want to be billed for air time upon entering
an area that enables the client to authenticate.
•
You are using a laptop on an airplane and want to prevent the adapter’s transmissions from
potentially interfering with the operation of certain devices.
When the radio is on, it periodically sends out probes even if it is not associated to an access point, as
required by the 802.11 specification. Therefore, it is important to turn it off around devices that are
susceptible to RF interference.
Note
Your client adapter is not associated while the radio is off.
Note
If your client adapter’s radio is turned off before your computer enters standby or hibernate mode or
before you reboot the computer, the radio remains off when the computer resumes. You must turn the
radio back on to resume operation.
