The new version of WifiInfoView (v2.90) allows you to easily export the information of one or more access points into a .pcap capture file.
For every access point that you select, a single beacon frame with all information elements is added to the .pcap file.
After generating the .pcap with WifiInfoView, you can open and analyze the access point information by using the Wireshark software.
