Chapter 8 Using the Aironet System Tray Utility (ASTU)

Pop-Up Menu

This window enables you to determine when ADU and ASTU run and to choose the options that appear on the ASTU pop-up menu. Follow these steps to make your selections.

Step 1 If you want ASTU 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 choose this option and later want to run ASTU, you must choose the Enable Tray Icon option from the Action drop-down menu in ADU.

Step 2 In the Menu Options portion of the window, make sure the check boxes of all the options that you want to appear in the ASTU 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 ASTU pop-up menu.

Step 3 Click OK to save your changes.

Enable/Disable Radio

This option enables you to disable or enable the client adapter’s radio. Disabling the radio prevents the adapter from transmitting RF energy. You might want to disable the client adapter’s radio in the following situations:

•You are not transmitting data and want to conserve battery power.

•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 enabled, it periodically sends out probes even if it is not associated to an access point (in infrastructure mode) or another client (in ad hoc mode), as required by the 802.11 specification. Therefore, it is important to disable it around devices that are susceptible to RF interference.

Note If the client adapter’s radio is disabled, your client adapter is not associated, and a message appears when you hover the cursor over the ASTU icon to inform you that the wireless network interface is disabled.

Note If your client adapter’s radio is disabled before your computer enters standby or hibernate mode or before you reboot the computer, the radio remains disabled when the computer resumes. You must enable the radio to resume operation.

If the radio is enabled, choose Disable Radio to disable the radio.

If the radio is disabled, choose Enable Radio to enable the radio.
