Select capture by applying packet-capture filtering | Options, expand the window to view the Capture Filter Bar. Double-click the selected interface, as shown, to eject the Edit Interface settints window.The Edit Interface Settings window is displayed, where you can set the packet capture filter condition. If you know the syntax for catching packet filters, enter it directly in the capture filter area. When an error is entered, the Wireshark indicates

Wireshark cannot capture wireless network card data Solution The capture session cocould not be initiated (failed to set hardware filter to promiscuous mode) always appears ). Solution: wireshark-> capture-> interfaces-> options on your atheros-> capture packets in promiscuous mode-set it off.
