You can capture the DATA (payload, i.e. IP/UDP/TCP traffic) by creating a
"bridge" first, and then capture the traffic on the other end of the bridge.

A bridge connects two adapters together, so traffic sent to one adapter, is
then sent through the other adapter.

You can then capture the traffic on the end of the bridge.

For example, you can bridge your wireless adapter to your regular
non-wireless adapter, and then capture the traffic on your non-wireless
adapter (which will be the same traffic that was sent to your wireless
adapter, because they are bridged together).

You will NOT be able to capture the "wireless" control information (i.e. you
will not be able to capture the "raw" wireless information such as the
wireless frequency and channel information, nor the wireless MAC headers,
etc).

Using a bridge, you will only be able to capture the "payload" information,
such as the IP packets, the UDP packets, the TCP traffic, etc.

The following video explains how to do it:
