    Must of munged something in network connection

    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:
    auto loiface lo inet loopback
    auto eth0
    iface eth0 inet static
    And rebooted the machine. The edit seems to have performed the desired function: the IP address is now Ifconfig returns:
    admin@CCD6:~$ ifconfig
    eth0      Link encap:Ethernet  HWaddr 00:13:20:c5:eb:0e  
              inet addr:  Bcast:  Mask:
              inet6 addr: fe80::213:20ff:fec5:eb0e/64 Scope:Link
              UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
              RX packets:4548 errors:0 dropped:0 overruns:0 frame:0
              TX packets:2818 errors:0 dropped:0 overruns:0 carrier:0
              collisions:0 txqueuelen:1000 
              RX bytes:3462392 (3.4 MB)  TX bytes:419965 (419.9 KB)
    lo        Link encap:Local Loopback  
              inet addr:  Mask:
              inet6 addr: ::1/128 Scope:Host
              UP LOOPBACK RUNNING  MTU:16436  Metric:1
              RX packets:12 errors:0 dropped:0 overruns:0 frame:0
              TX packets:12 errors:0 dropped:0 overruns:0 carrier:0
              collisions:0 txqueuelen:0 
              RX bytes:720 (720.0 B)  TX bytes:720 (720.0 B)
    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:

    [x] Enable Network
    Connection Information
    Edit Connections

    "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?
