sudo apt-get install wicd
Damn whitelist! Have to change the whitelist else the WICD icon won't show in the indicator display. Here I add both python and wicd to the whitelist (I could whitelist all but have had problems clicking on icons):
gsettings set com.canonical.Unity.Panel systray-whitelist "['JavaEmbeddedFrame', 'Mumble', 'Skype', 'python', 'wicd-client.py']"
Check that I can connect with WICD, then remove network manager
sudo apt-get remove network-manager
The default WICD icon is hideous in my opinion, luckily Will Laws has provided a revised set based on the default Network Manager set. Download the tar file from his site at the above link, then:
cp ~/Downloads/wicd-elementary-light.tar.gz .
tar -zxvf wicd-elementary-light.tar.gz
cp wicd-elementary-light/* /usr/share/pixmaps/wicd/
As mentioned above, the "usual" changes for slow shutdown of CIF drives didn't work, ie changing the run order at shutdown and reboot - see Ubuntu Wiki. I really do wish this basic problem, which seems to have been around for years, was resolved. The problem seems to lie with Network Manager shutting down before the CIF shares are unmounted.
