Hi, sam, I install 20060130 current to same note PC to compare 'current 20060130' and 'current 20060222'. After installing, I watch control message with 'tcpdump -n -i ath0 -y IEEE802_11'. When using '20060130 current', I can watch "Probe request" from my note PC. But I can't watch "Probe request" when using '20060222 current'. I add 'printf()' to codes and I check when 'IEEE80211_CHAN_PASSIVE' is set. I found ath_getchannels() at @src/sys/dev/ath/if_ath.c sets 'IEEE80211_CHAN_PASSIVE', because 'CHANNEL_PASSIVE' in channelFlags is set. I think ath driver send "Probe request" if ignore 'CHANNEL_PASSIVE' in channelFlags. So I add a code to ignore 'CHANNEL_PASSIVE' and to unset 'IEEE80211_CHAN_PASSIVE'. I test this test code at "broadcast SSID in beacon", and my note PC can associate an AP. It seems me current ath hal returns 'CHANNEL_PASSIVE' for all channels. In @src/sys/contrib/dev/ath/ah.h, comment for 'CHANNEL_PASSIVE' is "Only passive scan allowed in the channel". Does it mean my note PC can't send a probe message?
