[Pkg-utopia-maintainers] Bug#732391: network-manager: roamed from BSSID 02:25:9C:XX:XX:XX (myssid) to (none), ((none))

Package: network-manager
Version: 0.9.8.0-5
Severity: normal
Tags: upstream

Dear Maintainer,


i'm consequently losing connection to a wireless network with messages like

deauthenticating from 02:25:9c:XX:XX:XX by local choice (reason=1)

It is a WPA2 Enterprise network that also serves WPA with hidden SSID.

There are also other people in this network that have the same issue, in
particular seen with Intel Centrino Wireless-N 1000 wifi adapters. But I
don't think that it's related to that specific network card but to the
implementation how network-manager differs WPA and WPA2 networks.

When I'm using debian's interfaces configuration file with
wpa_supplicant I get a seamless network connection. That is - I guess -
because I can tell wpa_supplicant to only use CCMP pairwise/group ciphers.

I've also tried that with network-manager in the networks configuration file
[802-11-wireless-security]
key-mgmt=wpa-eap
proto=rsn
pairwise=ccmp
group=ccmp

but it doesn't seem to be properly honored, maybe the comment in the
source code is relevant here:

NetworkManager/libnm-util/nm-setting-wireless.c:
// FIXME: should handle WPA and RSN separately here to ensure that
// if the Connection only uses WPA we don't match a cipher against
// the AP's RSN IE instead


Despite of that I'm wondering why network-manager roams to a different
SSID. network-manager debug shows:

(wlan0): roamed from BSSID 02:25:9C:XX:XX:XY (myssid) to
02:25:9C:XX:XX:XX (myssid)
Activation (wlan0) successful, device activated.
[...]
(wlan0): roamed from BSSID 02:25:9C:XX:XX:XX (myssid) to (none) ((none))
(wlan0): supplicant interface state: completed -> authenticating
(wlan0): supplicant interface state: authenticating -> associating
(wlan0): supplicant interface state: associating -> associated
(wlan0): supplicant interface state: associated -> 4-way handshake
(wlan0): supplicant interface state: 4-way handshake -> completed
[...]
(wlan0): roamed from BSSID (none) ((none)) to 02:25:9C:XX:XX:XY (myssid)
(wlan0): supplicant interface state: completed -> disconnected

That '(none)' is the WPA newtork and '(myssid)' is RSN/WPA2.


Maybe that is a too kind of special situation and it's not worth
debugging - as WPA2 is actual standard now. But it would be nice if
networking would be working here with network-manager, too.


Thanks in advance for any comment
