configuration

I have been running UBUNTU 12.04 for a couple of months on this system with no problems. After a recent update, the bootup fails to define the wired network interface as eth0, so the default network configuration fails. ifconfig -a shows eth1 instead, as unconfigured. Booting from CD works OK, configures eth0 as normal.

Solution: sudo NetworkManager

The network manager figures out the situation, and configures eth1

Question: Where did this problem come from all of a sudden?
