No Internet

[fatsheep]

So I'm having a weird problem here... I have had Ubuntu set up on my Mom's computer for 2 years and this is the first time I'm having a major problem with it: it can't connect to the internet. I can't see any reason why and another computer on my home network can connect just fine (we're talking about a wired connection here).

I haven't diagnosed something like this in quite some time so I thought I'd ask for some help here. Here's some commands I ran:

anne@anne-desktop:~$ ping 192.168.0.1 <== this is the router
connect: Network is unreachable

anne@anne-desktop:~$ ifconfig -a
eth0 Link encap:Ethernet HWaddr 00:e0:4d:86:d5:f2

As you can see, I can't even successfully ping the router that I am directly connected to. Not sure what that's about...

Any help would be greatly appreciated. Just FYI I won't have access to the computer till next weekend so I may take till then to provide more information if it requires the computer. Thanks,

Jesse

1. Can you ping loopback?
2. Have you verified that the card works fine in another machine?
3. show us "sudo iptables -L -n"
4. Are you really a fatsheep? because I'm a fat ox

5. Do you also have no network icon?

6. I'm a semi newb, so I might be able to help you that much

From a terminal, try sudo dhclient eth0. Right now, eth0 has no IP address.

Also, unlikely as it might seem... check to verify that networking isn't disabled (make sure it's enabled).
