Bug Description

Binary package hint: network-manager

This is on Gutsy Gibbon.

Right-clicking on NetworkManager icon and unchecking Enable Wireless or Enable Networking has no effect.

There are situations where I would like to turn off wireless.

Also, in Dapper Drake disabling and enablling wireless was often enough to fix a connection problem, but now this can not be done. I need to kill -9 NetworkManager and restart it to get wireless working.

I've written about my system here: http://chandlerproject.org/Journal/UbuntuGutsyGibbonOnLatitudeD820

Same for me!

"I need to kill -9 NetworkManager and restart it to get wireless working."

I need to: sudo /etc/init.d/restart

Had the same problem. I upgraded from feisty and the network-manager behaviour changed.

Make shure that all interfaces in /etc/network/interfaces are commented out (except for lo).

auto lo
iface lo inet loopback

#auto eth0
#iface eth0 inet dhcp

#auto eth1
#iface eth1 inet dhcp

Is this you problem, too?

Hi Heikki,

I tried to reproduce the error, but NetworkManager is working fine (I can enable/disable the wireless/network).

Can you add the content of '/var/log/syslog' (as attachment) after reproducing the bug ?

Tip -> https://wiki.ubuntu.com/DebuggingNetworkManager

Thanks in advance!

This is caused by Network Manager unable to de-associate correctly from the Network.
So I'm marking it as duplicate of bug 145683, please try the network-manager packages currently in the proposed repository and if they don't fix the bug for you, feel free to un-duplicate the bug.
