prism2 + pseudo ad-hoc

[apartens at student.umass.edu]

Hi,
I am trying to get two D-Link DCF660w cards talking to each other in pseudo
ad-hoc mode. Everything works in plain ad-hoc, but as soon as I run the command
to switch to pseudo mode:
>iwpriv wlan0 pseudo_ibss 1
the connection dies. That is, I am unable to ping and the iwconfig
indicates Signal level = -100dBm, which apparently means the card is getting no
signal at all.

I am using hostap_cs 0.4.4-kernel.

If anyone has seen this before, please help.
Thank you,
Antony
