But there is the issue of 'creating' an IBSS. As I understand the spec, some node has to 'create' the IBSS by starting to send beacons, and then other nodes will join, and then send beacons. So the IBSS (assuming full connectivity) can persist even among nodes that are not creating the IBSS. But, if one wishes to operate this way among arbitrary nodes, it seems that the right thing to do is to have all nodes perform the creation. With Lucent cards, I have found that it isn't necessary to do anything special to make then join an IBSS as a non-creator. Regular mode (old '-p 1') would associate with a real BSS (AP) or an IBSS. But, with a netgear MA401, I found that I had to use '-p 0' to join an IBSS. I also found that these nodes could create an IBSS. Greg Troxel
