I recently updated my Ubuntu Live CD from 11.10 to 12.04, but now I have some trouble with the IP address.
Previously I simply edited the /etc/NetworkManager/system-connections/connectionXX file like this:
[ipv4]
method=manual
addresses1=192.168.0.2;28;192.168.0.1;
and it worked fine. I could see the address in ifconfig and could use the connection.
But since upgrade to 12.04, Ubuntu tries to create a new connection (possibly because of another MAC address in head line?) with DHCP. Furthermore, the wired connection is deactivated, so I have to activate it every time (and not all users know how to do it, so it is a bit troublesome)
How could I solve the problem?
