The logging showns nothing useful. Use wlandebug from src/tools/tools/net80211 to do: wlandebug scan and provide the log from the very beginning; not a snippet. If you see responses from the ap then check that probe request packets are going out; this can be done by adding something like wlandebug +debug It might also be useful to see what the channel config/setup is for the card; use ifconfig ath0 list chan to see it. Feel free to send stuff directly to me or provide urls so the list doesn't get spammed. Sam
