Ubuntu 11.04, classic desktop. Hardware is working fine, and network was working previously, but after changing my location (and rebooting the machine), Ubuntu just says 'Wired Network Disconnected'. Router shows working connection, and booting to XP gives a working network.
What could I try to fix this?
ifconfig shows eth0 interface with an IPV6 address only.
eth0 Link encap:Ethernet HWaddr 00:13:8f:81:88:89 BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) Interrupt:17 Base address:0xe800 auto lo iface lo inet loopback # This file is installed into /etc/NetworkManager, and is loaded by # NetworkManager by default.

Okay, new info: ifdown eth0 says
ifdown: interface eth0 not configured
