One last question - when you say that bridging cannot work with wi cards because they do not support promiscuous transmission, this makes me wonder two things: 1. Do you mean the wi driver does not support this, or you mean the actual physical card itself is limited in this way 2. I know that there are two major firmware differences between "old" lucent cards and "new" lucent cards, and that is that the old ones can be _actually_ set to SSID of "" and then pick up base station in range. Is it possible that (if the answer to #1 above is "it's a hardware problem") that the old revision cards are better at this, or are they all like this ? thanks a lot. I was actually _only_ interested in just plain old options BRIDGE bridging, and not being a virtual AP (so far). >Julian Elischer wrote: > >>bridging is not a function of it being a pc-card.. > > >This is true, particularly with netgraph bridging. > > >>actually bridging may already work with wi cards >>also netgraph bridgiung may also work... >> > > >Bridging cannot work with wi cards, since they do not support >promiscuous transmission (that is, sending frames with other than their >own MAC address).
