I am running wireshark on windows 7. I have an alpha usb wireless adapter. I have acrylic running and it sees various wifi traffic. So clearly, the wireless adapter is working and sees wireless traffic.

With wireshark, I get nothing.

I used this exact same computer and wireless adapter last year with wireshark and I captured 802.11 packets. I know acrylic has updated since then and so has wireshark. Is it because of those updates that I can't do this anymore? Or is there something else that I am forgetting to do?

Hi Are you explicitly selecting the interface when you capture, or just using Start capture button?

Assuming you're on 2.0.1 or higher, I would go under capture options

  • make sure you have the wireless interface selected with no filter.
  • Look at the little "Traffic" line graph to confirm that packets are showing up on the interfaces you expect.

    You could consider re-installing WinPcap if you're not seeing the interfaces/traffic you expect in the options menu.

    Thanks for the reply. I am selecting the interface and the litte "Traffic" line graph shows nothing going on at all. I don't have a filter on.

    I bet you are right that I should re-install WinPcap. But instead I just gave up on windows and went back to Linux.

    Hi. You could try to use latest Npcap 0.07 R3: https://github.com/nmap/npcap/releases.

    Npcap supports to capture 802.11 packets on ordinary wireless adapter (the one shipped with your computer)
