NetworkManager wont start
 
Hi,
I've been running CentOS on my laptop for a few weeks now. I don't know what happened today, but when I boot up, the NetworkManager wont show up on the panel, and I dont have access to wireless networks or internet. I tried booting my Windows partition and the wireless works fine. I can't seem to remember any latest change I've made aside from the wallpaper =) Any ideas where I should start debugging? I could see the module "iwl3945" still loaded. Here's a manual type of my lsmod | grep iwl3945

Code:

iwl3945          90177        0
mac80211        137929      1 iwl3945
cfg80211          30793      2  iwl3945,mac80211
Thanks!

#su

#system-config-network

Also do a yum upgrade

Thanks! I've tried that systemconfignework, set the wlan0 to Activate, and it said "Cannot activate network device wlan0". Does this add info?

Code:
[root@mortonlx log]# service NetworkManager start
Setting network parameters...                              [  OK  ]
Starting NetworkManager daemon:                            [  OK  ]

My cable works fine, I could get internet using that. I just use the service network restart.

My notification area seems ok. Is there any log files I could look into for NetworkManager to actually see what's happening?

This is really weird =(

Not sure if this helps:

Code:
[morton@mortonlx ~]$ nm-applet

** (nm-applet:10529): WARNING **: <WARN>  applet_dbus_manager_init_bus(): Could not get the system bus.  Make sure the message bus daemon is running!  Message: Failed to connect to socket /var/run/dbus/system_bus_socket: No such file or directory

Delete all connections and set your connections with

#system-config-network and the older tools


/var/log/

daemon.log etc


network manager is really mature in Fedora 12

Do I need to delete also the eth0? What do you mean by older tools?

Did you see my recent update on nm-applet?

Thanks!

UPDATES! If someone could explain the relation of this. What I did is that I followed this tutorial

http://sysdigg.blogspot.com/2008/01/...-centos-5.html

to disable SELinux. Then I reboot, and Networkmanager icon shows up again and I can connect to my wireless now. How's that so?
