Not enough information. First, have you tried on a wired interface, or in plain promiscuous mode on the wireless interface, with more success? In another words, is just the monitoring mode problematic or capturing in general? If it is just a monitor mode issue, what wireless card (chipset) does your machine use?

Sorry, My fault, In plain promiscuous mode, it work success(TCP, ARP...) . But in monitor mode , I can't see any 802.11packet be captured. And my wireless card is Network controller: Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter

One Answer:


This isn't likely a Wireshark issue but rather a HW problem. For one example, see here:,1671.msg5591.html#msg5591

And there are other complaints about using that chipset for this type of work (monitor/injection, etc.).

At this point I would change adapters - since this is likely a PCI based, obtain an inexpensive USB adapter that will do monitor+promisc mode. You can search here for specific chipsets, or try the aircrack-ng and/or the Kali Linux forums.

Per the FAQ, the original author of the question can accept the answer so others will know that an acceptable answer has been provided. I think the up vote is for non-authors to indicate that the like the answer as well.
