Starting a capture

To quickly start a live network data capture, select a network adapter and click the Start button on the Start Page.

To start a capture with user-defined configurations, follow the steps below:

  1. Select the Capture tab on the Analysis Mode Tabs.
  2. Select a wireless network adapter on the Adapter List section, and then the AP Status section will list all available APs.
  3. Select an AP, and then you will be asked to type the key if the AP is encrypted. You can also select more than one AP, but the APs must be of the same channel.
  4. Click Set Network Profile on the Configuration Info section to select a network profile. A network profile includes the settings about node group, name table, and alarms (See Network Profile for details).
  5. Select a proper analysis profile on the Analysis Profile section. An analysis profile includes the settings about analysis modules, analysis objects, packet buffer, packet filters, logs, diagnosis events, packet output, and view display. Capsa provides six analysis profiles by default, and you also can create new analysis profiles (See Analysis Profile for details).
  6. Click the Start button on the bottom-right to start an analysis project.

  1. You can run up to four analysis projects on the same machine at the same time.
  2. If you just want to analyze some specific packets on the network, you should use packet filters. Click Creating Filters for details.
