A Microsoft Windows computer running the Wireshark tool allows you to display,
log, and analyze captured traffic. The remote packet capture facility is a standard
feature of the Wireshark tool for Windows. Linux version does not work with the
WAP device.
When remote capture mode is in use, the WAP device does not store any captured
data locally in its file system.
If a firewall is installed between the Wireshark computer and the WAP device, the
traffic for these ports must be allowed to pass through the firewall. The firewall
must also be configured to allow the Wireshark computer to initiate a TCP
connection to the WAP device.

STEP 1
