title: How to capture probe request data or probe response data sent from wireless router
body: <p>I have a tplink-wr703n wireless router with OpenWrt.</p>
  
  <p>I know I can capture all kinds of data when the adapter is in monitor mode.</p>
  
  <p>I want to the adapter work in master mode, and I also want to capture probe request data sent from client or probe response data sent from my router.</p>
  
  <p>I have tried to use libpcap to capture data, but I failed.</p>
  
  <p>Can you tell me how I can get that data?</p>
