Is there any way we would be able to detect which devices/laptops in a
wlan( with one 802.11g AP) are using 802.11b & which are using 802.11g
cards?

Yes, turn off the 801.11 b support in the router. All the Gs will connect
and the Bs will complain about the loss of connection.

What type of device? Some of the more sophisticated enterprise systems
do this today. However, some of the lower end one's dont.

Sure. The status page on most of the better wireless routers will
display the connection speed. If you have command line access to the
wireless routers, diagnostic commands such as "wl" will deliver both
the connection status and the capeabilities of the client.

The speed information and more are transmitted in the 802.11 managment
packets and are also available to anyone with a passive sniffer such
as Kismet.

For more detail, kindly disclose what you're trying to accomplish and
what you have to work with.

Thanks for the answers,

"The speed information and more are transmitted in the 802.11 managment
packets and are also available to anyone with a passive sniffer such as
Kismet. "

If i user sniffer, what will i look for in packets which will determine
whether it's a b client Or g client. Will it be the protection bits?

" G APs announce whether Protection is required by setting a flag in an
"ERP Information Element" included in Beacon and Probe Response
packets. In the absence of B stations, the AP sets Use_Protection = 0
so that G stations can operate with greater efficiency. If the AP sets
Use_Protection = 1, all G stations must immediately begin using
Protection mechanisms to politely share the channel with B stations. "


Another question,is it possible to determine from mac address whether
its a b or g client( like we can do for vendor name)
