Subject: [PATCH] Improve passive scanning: check not only for proberesp_ies but also for beacon_ies
Date: Tue, 27 Nov 2012 15:27:51 +0100 [thread overview]
Message-ID: <50B4CDE7.9040308@neratec.com> (raw)
Improve passive scanning: check not only for proberesp_ies but also
for beacon_ies
Without this improvement, it always attempts to send a probe
request (which it's not allowed) and then wait for auth_data->timeout.
The log without patch:
