I succesfully installed WinPcap 3.0 as I can sniff traffic with Windump.
But when I try to use Ethereal this error appears:

The capture session could not be initiated (Error opening adapter: The System cannot find the file specified)
Please check that you have the proper interface specified.

Note that the driver Ethereal uses for packet capture on Windows doesn't support capturing on PPP/WAN interfaces in Windows NT/2000/XP/.NET server

Well this shouldn't be a problem as I try to use it on Windows 98.
And also it's not a PPP interface I'm trying to sniff.

The adapter name is: SANTIS WLAN USB Adapter: FVNETusbASKEY (AR)(R)

(It's an usb adapter for a WLan (Siemens Santis 50 wireless adsl router -> http://www.siemens.com/index.jsp?sdc...id=1669042413&)

I find this strange as I succesfully can sniff traffic using Windump. (And of course the adapter is properly installed as I am connected to the wlan and I'm online so)
Anyone know what the problem could be?
