802.11 Channel grayed out on Wireshark 1.10.1 for OS X


I'm trying to do WiFi capture on my Mac, but I can't seem to select the channel I want to capture on. The 802.11 Channel, Channel Offset, FCS Filter, and Wireless Settings are all grayed out. Here is my configuration:

  • Wireshark 1.10.1 (SVN Rev 50926)
  • OS X 10.8.5

Capture Options:

  • Link-layer header type: 802.11 plus radiotap header
  • Promiscuous mode: enabled
  • Monitor mode: enabled

Can you show us what is the output of wireshark -D command given from you terminal.

BTW: can you run wireshark from terminal wireshark and see if you see any error on the terminal after wireshark window is opened.

I always run it from the OS GUI. I get "command not found" when typing "wireshark" in the Terminal.

It looks strange. I've installed it from .dmg and have the same OS version you have and:

XQuartz 2.7.4 (xorg-server 1.13.0)

wireshark 1.10.1 (SVN Rev 50926 from /trunk-1.10)

My which command gives me this path for wireshark


Give it a try to see what logs do you get on terminal. If your wireshark is not even in that path and you can't find where it is, check system logs

tail -f /var/log/system.log

and open wireshark from GUI.

What type of installation did you do? Is it possible to reinstall it again? When you mount the .dmg image you will see a Read me first.rtf. Try reading it if you want to uninstall your current wireshark installation.

Let us know.

One Answer:

That's because Wireshark doesn't include any code to support using, for example, the CoreWLAN framework to control the channel for AirPort devices, as nobody's written that code.

The fact that those options are there at all is arguably a bug; they shouldn't be there on OS X unless and until Wireshark supports them on OS X.
