Ubuntu 12.04 using the LXDE desktop. We have a mixed wired and wireless network here, and I prefer to give wired devices fixed IP addresses. Most of the machines are Windows and assigning fixed IP addresses on them is easy, but I've run into trouble doing so on this 12.04 box.
I edited /etc/network/interfaces to read:
And rebooted the machine. The edit seems to have performed the desired function: the IP address is now 192.168.1.110. Ifconfig returns:
auto loiface lo inet loopback
iface eth0 inet static
dns-nameservers 18.104.22.168 192.168.1.1
But there used to be a little icon on the toolbar in the lower right corner, showing a plugged-in Ethernet connection, it's now gone. Network Connections doesn't show anything under the "Wired" tab. And right-clicking where the little icon used to be brings up:
eth0 Link encap:Ethernet HWaddr 00:13:20:c5:eb:0e

"Connection Information" says "no valid active connections found"
AND YET I am presently connected to the Internet else I could not send this.
So clearly I've done a Bad Thing. Thoughts?
