The devices from which the frames were captured are displayed across the top of the tab. A frame is selected by clicking anywhere on the line under the frame name. When selected, the frame is highlighted in blue.
When a frame is selected (highlighted), the frame data is shown in the hex values and decodes areas.
The decodes area shows the 802.11 interpretation of the frame data in a tree structure. The hex values area and decodes area are linked so that selections in one area will follow the selections in the other.
