Hello. Few days ago I bought wifi usb adapter for extended range reasons. it was installed properly on my macbook pro with mavericks. As results I can use it to connect on-line. I'd like to use Wifi Scanner application to gather more informations about hot spots around me. The problem is that Wifi Scanner recognizes only en0 interface that correspond to Wifi internal mac interface. The wifi usb external adapter isn't recognized. how can I do? Do you have any ideas?
