C'est compliqué de capturer le traffic de management comme trouvé dans la doc wireshark les trames de management et non data frame, sont souvent filtré.
Tu veux voir quoi exactement ?
Non-data packets
You might have to capture in monitor mode to capture non-data packets. If not, you should capture with 802.11 headers, as no "fake" Ethernet headers can be constructed for non-data frames.
Management Packets
Management packets are used by peer WLAN controllers to maintain a WLAN network, and as such is seldom of importance above OSI layer 2. They are discarded by most drivers, and hence they do not reach the packet capture mechanism. However, if adapter/driver supports this, you may capture such packets in "monitor mode" as discussed below.
