Hello! I'm a noob student who studying networking.
I want to eavesdrop every packets in my network, but I cannot capture 802.11 data frames...
I have total 4 devices -- 2 Macbook Airs, iMac, Desktop with Ubuntu 16.04. Every Mac has bcm43xx network adapter and Desktop has ath93xx network adapter.
I tried to capture every 802.11 frames in the air with using monitor mode, but I failed. Then, I turned every security stuff off and tried but it also failed too!
iMac and one-Macbook can capture 802.11 QoS Data frames but another Macbook and Ubuntu machine capture only CTS-RTS frames.
I want to know why my Ubuntu machine cannot capture any 802.11 data frames. And, as I wrote above, I have 3 Mac with same network adapter but just one Macbook cannot capture any data frames.
Summary : I have 4 devices :
For the difference between the Mac's... compare the WiFi driver versions on those two machines.
For Ubuntu, ensure you have the proper WiFi interface setup and detectable in WireShark.
