There is another IBSS bug that was introduced connected to rates maybe this is also your problem.. we have something in the pipe that should solve this. > please remember that there was a lengthy discussion about the standard > compliance and the reasons behind the need for IBSS merge before my patch was > accepted. i believe i had convincing arguments why IBSS mode does not > reliably work at all in practice if we don't support IBSS merge.
