I have a Cisco Aironet 350 wireless card. I use the software driver
furnished by Network General's Sniffer program for this device to
capture this information.
IEEE 802.11
Data Rate: 1.0 Mb/s
Channel: 5
Signal Strength: 75%
Type/Subtype: Beacon frame (8)
Dell Laptop WinXP SP2. I must stress the driver used is not one I've
found anyplace other than Network General.

Subject: [Wireshark-users] Using Wireshark to capture signal strength
anddata rate for 802.11 packets
Hello all,
I am currently evaluating the use of Wireshark to capture 802.11/wlan
packets and I have some questions.
1) Can wireshark display information like the data rate, signal and
noise level on each captured 802.11 packet? [This information is not
part of the basic 802.11 Frame Format but is provided by some wlan cards
as 'extra' header info for each packet. This info can, for example, be
displayed in AiroPeek.]
2) If the answer to 1) is yes, which wireless driver and OS must I use
to be able to capture this information from wireless cards?
I have looked at the wiki info on capturing Wlan packets
(http://wiki.wireshark.org/CaptureSetup/WLAN). While it does provide
info on various drivers and OSes that can be used to capture wlan data,
it does not explicitly say which combination of driver/OS will capture
packets that contain the above information that I am looking for.
Regards,
Kam-Yung
