IBSS beacon generation problem

[Sean]

I have made a seven node olsr mesh with the settings that I sent
earlier. This was using ndiswrapper with a VIA vt6655 card (horrible
card, by the way). The data is encrypted. It uses a group key, so it is
not extremely secure. But it is better than WEP. Also if I change the
group to CCMP (group=CCMP) it will use AES encryption, which is even
better. I have gotten it to interoperate with a third party access
point. I set the access point to adhoc with wpa-tkip and it will work
with my ndiswrapper card. Also if I set the access point to adhoc with
WPA2-AES and I set my group to CCMP it will also interoperate. I suspect
that my ap is downgrading to adhoc with wpa-aes but I am not really sure.

Give it a try!
