You mean BSSes, not stations, right? This is very strange - it seems those should be two entirely different code paths in the kernel. What driver are you using? But then again, you said nl80211/iw works, right? Then the driver shouldn't matter. Do you think you'd be able to use tracing? trace-cmd report -e cfg80211 -e mac80211 would report the calls to/from the driver and could perhaps shed some light. If you can record this, send me the resulting trace.dat file (compressed) off-list. johannes -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
