Philipp Gassmann, this bug was reported a while ago and there hasn't
been any activity in it recently. We were wondering if this is still an
issue? If so, could you please test for this with the latest development
release of Ubuntu? ISO images are available from

Joseph, why have you changed the status to Incomplete? Should we report
another bug about the kernel or what additional info do we need? Are
there any upstream kernel bug about this?

Forgot to add the same bug tag to close the bug with the network-
manager-applet, but it now also contains code to fix adhoc WPA. We can
close this as Fix Released.

Adding the nm-applet task because we'll be adding code in both NM and
nm-applet to workaround this.
FWIW; it's indeed been broken for a while:

@mathieu-tl can you rely on your quick test connecting with android?
Android doesn't support Adhoc per default. With the App Wifi-Analyzer
you can see some details.
When I create an AdHoc and select WPA, it's now recognised as WPA. WPA2
would be better, I guess. But before it was open.
Why is it
I can reproduce this using a laptop with iwl4965, and a Nexus One.
In Wifi-Analyzer, it is displaying as being WPA with a lock icon, but
when I go into the wireless settings, it says Open. I can definitely
connect without a password, and can access the Internet through the
adhoc network.
I agree
Philipp; yes, we can rely on that test because Android does support ad-
hoc for WPA. WPA2 is another story ;)

We've been able to reproduce it on multiple drivers: iwlwifi, rt2800pci,
ath9k and iwl4965. I think we can safely say it's reproducible on most
drivers, and thus probably something that needs to be fixed in kernel
code outside of drivers' code.

Running wpasupplicant on the command line with debugging logs enabled
shows that it does think it's enabling WPA, even if that doesn't seem to
get done at the kernel level.
** Attachment added: wpa_adhoc_debugging.txt
The above was tested with the simplest form for enabling IBSS/WPA,
inspired from the default wpa_supplicant.conf shipped configuration,
from the upstream tarballs:
mtrudel@gaea ~/Documents % cat wpa-adhoc.conf
ap_scan=2
network={
ssid=test adhoc
mode=1
frequency=2412
And the same on a different system, with ath9k (with the host using
iwlwifi):

Using static IP addresses to configure both, they are mutually reachable
which proves they are associating to the same BSSID.

I checked the behaviour of previous releases with LiveCDs.
On 11.04 creating a WPA WLAN leads to an open network.
On 10.10 I saw a WEP secured net (in Wifi Analyzer, Android) but the connection
information in Ubuntu said WPA.
I think it's the behaviour or Ubuntu 10.10 which led me to think it
Even IBSS/RSN seems to either appear as not secured, or fails to be
connected to with a quick test using my android phone; we'll explicitly
disable WPA when creating ad-hoc networks instead.

This issue is reproducible even without NM, using wpasupplicant directly
to create a adhoc network, and is definitely true on iwlwifi and
rt2800pci; so it deserves to be looked at at the kernel level.
FWIW, I though I had seen it work properly on ath9k, I'll test again
tomorrow to be certain.
In
This isn't quite done yet because making IBSS/RSN (adhoc with wpa2) the
default instead of WPA with TKIP (as wpa-none) turns out to be a little
more difficult to implement and test than initially expected. So; I'm
still working on this.
** Changed in: network-manager (Ubuntu)
Status:
Indeed, it's borked. This should be set to High considering it's a
security vulnerability; perhaps I'd just go ahead and grey out WPA from
the list if that makes a bit more sense and avoids getting people to
think their ad-hoc is secure when it's not.

Yes, please do. Either we fix it to properly set up WPA, or we remove
WPA from the list, but having it display WPA and actually set up
