Hi Chris,

Many Windows drivers for Wireless cards do not support the "promiscuous" mode well. Do you see any packets when you start a capture with promiscuous mode off? Of course this means you will only see broadcasts, multicasts and unicasts to/from the pc running Wireshark.
Cheers,


Sake

Hi folks,

I had a customer of ours install Wireshark 0.99.6a and WinPcap to help
us disgnose a networking issue involving their Windows XP system. No
matter what form of installing, uninstalling, rebooting, etc. we did,
we could not get Wireshark to capture on his wireless interface. What
I am used to seeing is when I open the Capture -> Interfaces window, I
see packet counts on active interfaces, even if capture is not
started. I see no packet counts on any of his interfaces even though
his computer is clearly connected to the internet. Then if I try to
capture on the wireless interface anyway, I see no packets captured.

What kinds of things can I do to diagnose what's going on here?

Thanks in advance.

Chris
