How to create a pcap using Wireshark

Wireshark has an option called promiscuous mode. Promiscuous mode allows you to see all packets on the network, not just those for your network adapter. This should be enabled by default but please check by going to Capture > Options and making sure the checkbox is selected towards the bottom of the window.

When opening Wireshark you will see a list of available network interfaces under the Capture heading on the main screen. From here you can double-click the network interface that you would like to start capturing data for.

After double-clicking a network interface you will start to see the packets sent to and from your system in real time.

Once you have enabled Wireshark and re-created your issue, you can then stop the capture by selecting the red square stop button in the toolbar. The packet capture can now be saved by selecting File > Save.

Promiscuous mode should be enabled by default, this will allow you to see all packets on the network, not just those for your network adapter. You can check that promiscuous mode is enabled by going to Capture > Options and making sure the checkbox is selected towards the bottom of the window. If promiscuous mode was not enabled, please enable and start a new capture.

The created pcap file can then be emailed to the Dial 9 support team if requested.
