Ethereal uses WinPcap, on Windows, to do traffic capture; it uses
libpcap on UN*X.
May i know, can ethereal or winpcap capture signal strength or noise of
a wireless client.
Ethereal can, but not on Windows...
...because WinPcap can't. WinPcap has a driver that connects to network
adapter drivers, but it doesn't include any network adapter drivers - it
relies on the capabilities of network adapter drivers in the system,
and, as far as I know, none of the vendor-supplied or Microsoft-supplied
drivers supplied for 802.11 network adapters on Windows support
supplying radio information such as signal strength with captured packets.
Ethereal *can* do so on Linux, and on some BSD systems, with some
adapters and drivers.
