NetworkManager broken

Hi,

I haven't been able to use NetworkManager for a couple of months now. It broke after some update but unfortunately I can't pinpoint which one but it was around when kde 4.6.0 and kernel 2.6.37 were released.  I have eth0 (b44) and wlan0 (b43). 

My package versions:

kernel26 2.6.37.2-1
networkmanager 0.8.3-0.20110113
kdeplasma-applets-networkmanagement git20110304-1
wpa_supplicant 0.7.3-1
kde 4.6.1

Relevant parts from rc.conf:

INTERFACES=(lo !eth0)
ROUTES=(!gateway)
DAEMONS=(syslog-ng netfs @xinetd @crond !hal dbus networkmanager @proftpd @sshd @mysqld)

I have my wireless network (having WEP encryption) configured in KDE's network manager applet, it detects the network on startup and tries to connect to it. First it asks for key again (key is filled in in dialog and is correct) and then reports connection failure. From log it seems that dhcp somehow fails:

Error log contains this:

 NetworkManager[1238]: supplicant_interface_acquire: assertion `mgr_state == NM_SUPPLICANT_MANAGER_STATE_IDLE' failed

I haven't found yet what might cause this...

The same configuration was previously working.

If I stop networkmanager daemon and run this script that manually sets the network up, everything works perfectly.

#!/bin/sh
ifconfig eth0 down
ifconfig wlan0 up
iwconfig wlan0 key mywepkey
iwconfig wlan0 essid mynetwork
dhcpcd

That means wlan hardware, driver and dhcpd is working.

Has anyone experienced something like this? It doesn't even work when I log in as root...

thanks.

Re: NetworkManager broken

It might be related to the upgraded consolekit (0.4.1 > 0.4.3) which occurred about that time.

Do a search for consolekit and networkmanager and see if you can find it. It affects (amongst others) people who don't use gdm to login.
