No Internet Connection (DHCP)

I boot up and first thing I type: ifconfig
I get:

eth1 Link encap:Ethernet  HWaddr 00:C0:F0:56:2E:E9
 inet addr:192.168.0.1 Bcast:192.168.0.255 Mask:255.255.255.0
 UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
 RX packets:4 errors:0 dropped:0 overruns:0 frame:0
 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
 collisions:0 txqeuelen:100
 Interrupt:9 Base address:0x2000

lo Link encap:Local Loopback
 inet addr:127.0.0.1  Mask:255.0.0.0
 UP LOOPBACK RUNNING  MTU:3924  Metric:1
 RX packets:6 errors:0 dropped:0 overruns:0 frame:0
 TX packets:6 errors:0 dropped:0 overruns:0 carrier:0
 collisions:0 txqeuelen:0

So eth0 is not UP. Then I type: ifconfig eth0 up
and then I type: ifconfig
and I get:

eth0 Link encap:Ethernet  HWaddr 00:20:78:E0:00:8A
 UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
 RX packets:7 errors:0 dropped:0 overruns:0 frame:0
 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
 collisions:0 txqeuelen:100
 Interrupt:10 Base address:0x1800

eth1 Link encap:Ethernet  HWaddr 00:C0:F0:56:2E:E9
 inet addr:192.168.0.1 Bcast:192.168.0.255 Mask:255.255.255.0
 UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
 RX packets:19 errors:0 dropped:0 overruns:0 frame:0
 TX packets:6 errors:0 dropped:0 overruns:0 carrier:0
 collisions:0 txqeuelen:100
 Interrupt:9 Base address:0x2000

lo Link encap:Local Loopback
 inet addr:127.0.0.1  Mask:255.0.0.0
 UP LOOPBACK RUNNING  MTU:3924  Metric:1
 RX packets:8 errors:0 dropped:0 overruns:0 frame:0
 TX packets:8 errors:0 dropped:0 overruns:0 carrier:0
 collisions:0 txqeuelen:0

So, as you can see, eth0 is NOT assigned an inet addr:

As a result, I have no internet connection.
This is particularly frustrating because it was on the internet just
fine the other evening. I didn't purposely change anything, but now the
internet connection is lost.

I've taken all the advice I've gotten so far, but I'm still not online.
Here's my files for scrutiny. Thank you so much for any help!
