How to catch the Ad-Hoc station beacon with an Orinoco card?

[Hiddink, Gerrit (Gerrit)]

Hi,

do you mean the "WaveLAN ad-hoc" mode, or the IEEE Ad-Hoc mode
which is also known as peer-to-peer mode or (more formally)
Independent BSS mode? 

Well anyway if you are seeing beacons if you put it in "ad-hoc"
mode, then apparently it is the IBSS mode that you're using.

Regards, Gerrit
