>Description:
Adding a run interface to the machine in hostap mode. In all of WEP, WPA and no crypt, clients can associate. In WEP or WPA mode, a circumstance like usb/132722 arises: no lease can be had, and traffic on the run looks the same in tcpdump, unknown SSAP, unknown DSAP...

In no crypt mode, a lease can be obtained, but performance is poor; it appears some frames are being transmitted back to the client corrupted.

I can provide IEEE802_11_RADIO or regular tcpdumps, if that would help, but they're pretty mundane, so before I did I figured I'd ask what you actually want to see rather than just dropping a large blob at you.
