A couple possibilities: 1. I recall on OpenWRT the default compilation flags resulted in getting no signature back via hostapd_cli. However I think it failed all CLI commands, and you said all_sta works, so that is likely not it. 2. hostapd has to have seen both a probe request and an association request from the client before it can form a signature. There are a few clients which are very sparing in sending probes, notably ChromeOS. The client can be joined via just seeing the beacon and sending an Associate Request, but not have a signature until hostapd sees a probe. _______________________________________________ Hostap mailing list Hostap@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/hostap
