I came to know about Kali Linux and thought that being powerful enough to do security testing I would be able to use it as a sniffer in monitor mode.
Bought myself the Alfa AWUS036ACH but I can't capture 802.11ac VHT data frames. I have open mode connections (no encryption).
I suspect this has is perhaps because I'm not configuring the monitor mode properly, in the sense that perhaps I'm not picking the proper BW, or center frequency or so.
I would appreciate very much if someone can help me by 1) confirming if it's actually possible to capture data frames with this sniffer and 2) how to do it.

Thanks beforehand.
