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.
