Yes, since Windows doesn't support creating an AP from the card, and it=20
connects to Windows. Unless there are other modes that can do the same=20

[nomenclature: let's call the FreeBSD machine with the rum interface,=20
the one I wish to associate the device with, the "gateway" and the other =

one the "laptop"].

I have a scan from the the laptop, but apparently it doesn't record all=20
- only beacons and probe responses are in the dump and only from two=20
nodes - my own and one of the neighbours' (but it's a noisy neigbourhood =

and the device finds at least three more APs.

Here's a sample:
