I am trying to share my Ubuntu 11.10 internet connection via my wireless to another computer via ethernet. When I try to share them I get this endless "Connection Established"/"Disconnected" loop. I've tried updating everything, tried using Firestarter, tried everything I knew to. The card is supported for this because I was able to do it back in 11.04. Any help would be nice. :)
ICS seems to work perfectly despite the messages.
Go to the IPv6 Settings tab for the ICS connection, set the method to Ignore and uncheck the Require IPv6.... box.
it is recommended to set IPv6 to "Ignore" and
worked for me
