It's more of trying to understand how an ad-hoc network works. Thanks
for the info.
One more question: if the initial scan does not reveal an existing
IBSS and one is created instead by wpa_supplicant, how is the RF
channel selected? Is this at random or are there specific rules that
determine which channel will be used?
Is there a wpa_supplicant option to configure the channel to be used for a IBSS?
