what to capture wireshark packet sniffer wireless

Let it broadcast an SSID so the radios switch on but do not broadcast the same SSID you are troubleshooting so that clients do not connect to your second capturing AP. Change that second AP's wireless channel to match the AP that is being troubleshot. If this information is needed, then the real capture should be done from a close-by second AP. The capturing AP will not report its own Beacons, Re-transmission, Acks and 11n Block Ack. The capture on wifi0 and wifi1 will not include internally generated hardware packets by the capturing AP.End the packet capture upon completion of transmission and save the trace for further analysis.Begin the test packet transmission on the suspect device.To determine what radio the test client is on, please view and locate the test client in one of the reports on the wireless controller such as 'Clients by VNS'. If you want to capture the radio (air) that the test client is on, check off wifi0 for Radio 1, or wifi1 for Radio 2. Note: If you want to capture the wired port, make sure eth0 is checked off (selected). Select the interface(s) you want to capture packets.Keep the default 'Null authentication' radio button selected.Type the IP address of the target AP in the ' Host:' box.Click on Remote Interfaces tab, then click 'Add' ('+' button in lower left corner).The Manage Interfaces window will open.Click on Manage Interfaces button (located in the lower right corner of the main window).

Open WireSharkand click on Capture and then Options.

Make sure the AP is reachable from the PC running Wireshark.

Step-2: Configure The Wireshark Network Analyzer application ('Wireshark') to start capture from the remote host (i.e.: Access Point)

Set preferred duration of traffic capture (default is 300 seconds).

Go to the Advanced under AP Properties of the AP.

Note that access point's IP from it's Static Configuration (This information will be needed when configuring The Wireshark application).

Identify the target Access Point (AP) in the Controller GUI interface.Step-1: Configure the target access point by following the steps below:
