Can you please compile up athstats (/usr/src/tools/tools/ath/athstats) and make sure your kernel has the following options: options ATH_DEBUG options AH_DEBUG options ATH_DIAGAPI Then run scan for a while and use athstats to see what (if any) is being received. Something tells me it's a weird antenna or RX gain issue. You should be _seeing_ something, even if you aren't able to TX probe request frames correctly. Also, you could fiddle with diversity/RX antenna settings: sysctl dev.ath.0.diversity=0 # or 1 to re-enable diversity sysctl dev.ath.0.rxantenna=0 # or 1 or 2 to hard-code antenna selection sysctl dev.ath.0.txantenna=0 # or 1 or 2 to hard-code antenna selection I've seen weird behaviour before where only one antenna was connected.
