As far as I can understand, NetowrkManager first checks /etc/network/interfaces file too check which of the interfaces are present in the file and what needs to be handled by it. Initially I was switching between wired interface (eth0) and my wireless interface (eth1) and then NM was handling it perfectly. In between I had to use pppoe to connect to internet through eth0 for a few days and I suspect it to have made my eth0 to be manually set. When I returned back to my original swapping between eth0 and eth1, NM found an entry in interfaces file for eth0 and hence didn't get initialized as it was being handled otherwise. (I do not turn on eth1/wireless when am using wired connection). Hence NM had no interfaces to handle and hence wasn't showing the applet.
When I manually started NM, it had to force load the applet as well and as NM by itself wasn't handling the interface eth0, it had no interfaces to display using nm-applet and hence it was completely disabled. Also I came to know that System > Administration > Network menu option has been removed in Intrepid. But, I wonder how we will handle network management through a GUI otherwise? -- not connected to network when booting https://bugs.launchpad.net/bugs/290973 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
