That manfid is unfortunately used by most of the manufacturers making
cards using the Prism2 chipset (which includes the IBM card).

Note that the ESSID will not be displayed properly if the interface is
not up. This is misleading, but I haven't had time to fix it yet.

Are you using the same ad-hoc mode - there is both IBSS (802.11
standard) ad-hoc mode (the default) and demo (Lucent proprietary)
ad-hoc mode which are not interoperable. If the other stations are
using demo ad-hoc mode, use the command "iwpriv ethXX set_port3 1" to
activate this mode.
