I have to admit that the firmware is weird and I have frustrutated with multiple times. Maybe it's now preventing probe requests and only allowing authentication and association requuests? If you can hack mac80211 to skip or ignore probe request phase, that might tell us more. > However, there is still nothing seen on the monitor interface and it > is seeing plenty of other traffic.

Unfortunately I'm busy with other stuff and I can't test it. But if you can send the patches anyway, and if I find the time at some point, I can test it with my device. -- Kalle Valo -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
