bschmidt 2011-06-04 11:43:09 UTC FreeBSD src repository Modified files: sys/dev/iwn if_iwn.c Log: SVN rev 222679 on 2011-06-04 11:43:09Z by bschmidt The firmware of 4965 series adapters seems to die while trying to send probe requests at 1Mbps while being associated on a 5GHz channel. Sending those at 6Mbps does work, so use that instead during a background scan. This workaround allows us to re-enable background scan support for the 4965 adapters. Also, just enabling one antenna on 5GHz results in better reception of beacons: test 00:26:5a:c6:14:1a 40 54M -71:-95 200 E WME HTCAP ATH vs test 00:26:5a:c6:14:1a 40 54M -92:-95 200 E WME HTCAP ATH Due to roam:rssi thresholds set to 7 by default it might have been impossible to associate to that network. While here use IEEE80211_IS_CHAN_5GHZ() to determine the band. Revision Changes Path 1.112 +10 -6 src/sys/dev/iwn/if_iwn.c
