I used to be able to share my network connection by editing the Auto Eth0 to share with other computers in the Ipv4 section and now I upgraded my laptop to 11.10 .

Now are there no wired connections in the network manager. When I click my connections applet at the top of the tray it also says wired device not managed!

when I type ifconfig -a

daniella@daniella-1001HA:~$ ifconfig -a
