Hello freebsd-wireless,

I would like to prevent a USB Wifi card from automatically connecting
to an unencrypted network nearby.  It happens whenever the card is
plugged to the USB port and the wlan0 interface is brought up.  After
a few seconds it's connected to the first unencrypted net it can find.
How could it be stopped?

Thanks for help!

Stefan
