I left Ubuntu and came back after a while so I don't remember much. Now I'm trying to get my IP address. All I'm getting from running ifconfig is
eth0 Link encap:Ethernet HWaddr 3c:97:0e:11:22:0d
UP 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:20 Memory:f2500000-f2520000
(BTW, I don't really understand what UP BROADCAST MULTICAST means.)
$ sudo ifdown eth0
ifdown: interface eth0 not configured
Then
$ sudo ifup eth0
Ignoring unknown interface eth0=eth0
And finally 2:
$ ip addr show eth0
eth0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN
group default qlen 1000 link/ether 3c:97:0e:11:22:0d brd ff:ff:ff:ff:ff:ff
ip ifconfig

You might just try setting your IP address to something on your subnet. Assuming you're on a 192.168.1.255 network, try this:
ifconfig address 192.168.1.50 netmask 255.255.255.0 gateway 192.168.1.1
Replace 192.168.1.50 with the IP you want to get, and replace 192.168.1.1 with the IP address of your router/gateway.
I have had a similar problem, and this solved it for me.

Try :
ifdown eth0
ifup eth0
ip addr show eth0
The meanings of UP, BROADCAST, and MULTICAST
UP- device is functioning
BROADCAST- device can send traffic to all hosts on the link
MULTICAST- device can perform and receive multicast packets

NO-CARRIER means that the network jack detects no signal on the line. This is usually because the network cable is unplugged or broken. In rare cases it can also be hardware failure or a driver bug. Have you checked the cables and rebooted the system?
