I need to capture all 802.11 packets (data-control-management, Even those with
errors or not adhering to protocol) that can be seen by a WLAN Device, I am
open to changing my OS to get the best out of the tool. Till recently I was
using an outdated version of Observer (with support for 802.11b cards only) for
my work. Now I am looking at alternatives before I decide on upgrading my
license.
Recently I managed to install Linux on a Laptop with the necessary madwifi
drivers and have started evaulating Ethereal for Packet capture and analysis.
At first cut Ethereal looks as good as (or even better in some respects) than
Observer for the kind of work I do(debug and testing of WLAN devices). So I am
trying to find out Ethereal strengths and weaknesses compared to its commercial
couterparts.
