One of the many features Acrylic WiFi has to offer is its WiFi network traffic viewer, which allows you to analyze and view the IEEE 802.11 data packet captured during a WiFi analysis under Windows. This feature is disabled by default when Acrylic is launched.

The data package viewer can be enabled by clicking on the “Packet Viewer” button on the Acrylic WiFi main menu bar, or by clicking on the “View packets” button on the “Packets” section.

After activating real time packet capturing, icons change their status, the “Packets” section button and the main menu button display “On”.

In the “Packets” section, you see all 802.11 standard network packets grouped in three types: Management, Control, and Data, as well as the subtypes within each type.

Due to the large number of 802.11 standard network packets captured, it is necessary to apply a filtering mechanism to select only certain packets. To do exactly that, Acrylic WiFi has the “Filter” field.

By clicking on the “Help” button, you get assistance on the filter formats that can be used, valid operators, and also some filtering examples.

Acrylic WiFi packet viewer can be used for visualizing information elements from a captured beacon packet and get details on the used encryption. In this case, a WPA2-CCMP encrypted WiFi network search will be performed.

To perform this search, the Information Element RSN (Robust Security Network) “pairwiselist” field is checked to verify if there is any 00:0F:AC:04 packet, which indicates the use of this encryption suite.
