Bug Description

Binary package hint: plasma-widget-networkmanagement

Steps to reproduce:

1. Click on the Plasma network management applet and click on "connect to other network".
2. Select "New Ad-hoc network..." in the menu that appears.

A dialog box to configure the new ad-hoc network being created appears.

Try checking /var/log/daemon.log when attempting to connect to an Ad-Hoc network. I suspect you may see something like this:

If that is the case, this appears to be the bug we're both being affected by. I spoke to one of the Network Maanger maintainers and what he said was:

So this log indicates that the applet isn't creating the connection correctly and providing it to NetworkManager after you click the

Can you confirm that you see the same log entries?

I am running Jaunty.

I get absolutely nothing when trying to create an ad-hoc network, and only silence in /var/log/daemon.log

This is for Karmic. It is possible that Jaunty logs to a different log
(perhaps /var/log/NetworkManager.log?).

I'm really not sure that is relevant though -- does Jaunty even use the
same applet as Karmic? I think probably not.

It appears as if I may have gotten around this one by removing the "network-manager-kde" package and rebooting. Give that a shot! The reason I chose that package is that it seemed to bear a very close resemblance to the package mentioned in these links:
http://<email address hidden>/msg10610.html

It seems like the bug here is actually allowing that package to coexist on the system. It actually is not in any repository that I can find, and may be the result of having upgraded from Jaunty.

I've upgraded from Jaunty too. I don't have network-manager-kde installed, since "sudo aptitude remove network-manager-kde" says

No packages will be installed, upgraded, or removed.
0 packages upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
Need to get 0B of archives. After unpacking 0B will be used.

I can't check now, since I seem to be affected by another bug: clicking (left- and right-) on the plasma applet says "Network Management disabled" - it makes sense to me to always include with such a message an "I don't care, enable it now!" button, but apparently that's not how things work. :-(

This also reflects a disturbing trend of GUI frontends simply swallowing and ignoring errors instead of reporting them.

Just checked - there's nothing in /var/log/daemon.log after trying to create a new ad-hoc network.

This is still true on Lucid.

I have a similiar problem in debian testing and I think it's the same:
"plasma-widget-networkmanagement" does not apply the ad-hoc setting to the network settings.
You can open "Manage Connections…" and change the mode of the network in question to "ad-hoc".

Same here.
Ubuntu 10.04. Fully Updated. Installed KDE 4.4 from default repositories in synaptic. Attempted to created new Ad Hoc network as described above but nothing happened. Since I need wireless I have no other choices to leave KDE and get back to Gnome until it solved or I have enough time to start participating in KDE development!
Please solve it men.
