interesting message:
airo(eth0): WPA unsupported (only firmware versions 5.30.17 and greater
support WPA. Detected 5.30.17)
airo_test_wpa_capable assumes that the softSubVer part of the firmware

The problem here is that the bcm34xx driver and the ieee80211
stack do not agree on what channels are possible for 802.11a.
The ieee80211 stack only wants channels between 34 and 165, while
the bcm43xx driver accepts anything from 0 to 200. I made the
bcm43xx driver comply with the ieee80211 stack expectations, by
using the proper constants.

This patch recognizes WPA-capable firmware versions and adds support for

With this patch, a new promiscuous mode is enabled. If the module is loaded
with the rtap_iface=1 module parameter, two interfaces will be created
(instead of just one).
The second interface is prefixed 'rtap' and provides received 802.11 frames
on the current channel to user space in a radiotap header format.
Example usage:
% modprobe ipw2200 rtap_iface=1
% iwconfig eth1 essid MyNetwork
% dhcpcd eth1
% tcpdump -i rtap0
If you do not specify 'rtap_iface=1' then the rtap interface will
not be created and you will need to turn it on via:
% echo 1 > /sys/bus/pci/drivers/ipw2200/*/rtap_iface
You can filter out what type of information is passed to user space via
the rtap_filter sysfs entry. Currently you can tell the driver to
transmit just the headers (which will provide the RADIOTAP and IEEE
802.11 header but not the payload), to filter based on frame control
type (Management, Control, or Data), and whether to report transmitted
frames, received frames, or both.
The transmit frame reporting is based on a patch by Stefan Rompf.
Filters can be get and set via a sysfs interface. For example, set the
filter to only send headers (0x7), don't report Tx'd frames (0x10), and
don't report data frames (0x100):
% echo 0x117 > /sys/bus/pci/drivers/ipw2200/*/rtap_filter
All your packets are belong to us:
% tethereal -n -i rtap0
