Hello,

The wireless doesn't work on my Ubuntu 9.04. I've been in another country for a year and was working on a wired connection the whole time, but now I'm back home and nothing works. Ubuntu can't even look for signals because the Network Manager isn't working! I keep getting this:

darkfire@Basilisk:~$ nm-applet --sm-disable

** (nm-applet:3743): WARNING **: <WARN> applet_dbus_manager_start_service(): Could not acquire the NetworkManagerUserSettings service as it is already taken. Return: 3


anyone know what to do?

I am having a similar problem. When I start up nm-applet loads and starts as usual, but after a while it disappears from the taskbar and wi-fi connection quits working. When I open bash and manually restart nm-applet it works again, but even then I've seen the network manager occasionally stops working:



iris@irisgarden:~$ nm-applet

What is signal 15?

I have re-installed network-manager from the official Ubuntu repository using Synaptic, the same problem still continues. I had deleted /etc/network/interfaces file (a suggested solution found through Google), but it made little difference if any.

If the proverbial "s" hits the fan, are there any alternative to using network-manager or nm-applet -- or can I even sniff and connect to wi-fi using terminal commands (this would also be useful when I have to use fail-safe terminal if something goes awfully wrong with the GUI)?


This is Ubuntu 9.04

I have the same issue as missirismissiris. Ubuntu 10.10 everything fresh out of the box. Running nm-applet fixes the problem temporarily, but it keeps crashing.


$ nm-applet

Forget 10.10, I have the same problem with Ubuntu 11.04 !!!
I think it's high time somebody does something about this bug...

This is kind of an old thread here is a way to just sort of reboot the network-manager

sudo service network-manager stop

sudo rm /var/lib/NetworkManager/NetworkManager.state

sudo service network-manager start

It very well could be a driver problem and not network-manager at all.
Start a Thread and supply users with Network cards:

sudo lshw -C network

iwconfig
