Note to everybody: _Please_ provide the exact output. This text above makes it sound like we deauth from the AP, when in reality the AP has deauth'ed us. Maybe your AP is just buggy and can't handle you going away for more than a couple of seconds? It _looks_ like it sends you a deauth frame while you're scanning (please verify using wireshark or similar), we miss that deauth because we're off the channel, and then when we get back and start sending data again the AP complains that we're no longer authenticated. Sorry, but there's not enough information here to tell what really is going wrong. The known bug shouldn't be able to cause this behaviour. johannes --=-tVqiulh6Qn+pYrrQrKXZ Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Comment: Johannes Berg (powerbook) iQIcBAABAgAGBQJJ5v5dAAoJEKVg1VMiehFYjGEP/2ECTpji3u3+9HbNhCljjdLz i+nvfwSIjo4SrmqtpLq8WlkhMQ4oRfgBEQPke1RN3kMeQU5nKqh8iEqLPEa8RsJt DDSZLE9rWtrHTCNWwMxsrga3Py2OrXoePj8FGCpI0QM61tUelb0izt4j9+i3M06D Y8H79JhKuIH4Xl3rQFmc0oTkX+x0PbXvq/ePt4cmjQCd8HX5mm8gEhmqY12Hs1si oB0vK2tRhzQXqLbqwoQPuUT94mPhCwRpc2N+y4s+vqkHBuy9ISdyn70hEwgSrSNX 7Md8iSLo3iMy8bhC2bIwlAEYIqqWI4HaLOrxzU7sC/gZgh6KONP4fj6wruPiipzB B9kKki8NxdOZehGAxTXsP54zt4XAK27LwKAuh+kCiARr2qyN4woK2JVwKmHtclOo 5BJMoUaBTdEpV70jAyH73CuIBSgALmRoV5q1Bi75sYnlQCNvcAqSC7SPTLJVLd3W JyLFtKNmZb7Uvw2HZDrMqRrJEw3q901zuayyBU60PvirN5cPGcjezQmmGRoeR9Zf vdWm2htf6Gt1sSmn0kc6kVJLYCOISV2HxIstKWg3IeLnRydfCs/LWVAbXeCQ/ckT o+K4ryFkBvS0qM3bd3W8O1SUIVhrtvmrcvasDzZKVnjVWnV498Rva+zAahCtYSTP Yx5NV013J1mt4D3MD1JG =JsyO -----END PGP SIGNATURE----- --=-tVqiulh6Qn+pYrrQrKXZ--
