Ubuntu Internet connection problems

[sierradawes]

I have never used Ubuntu before and decided to give it a try. I have an older computer that someone gave me and figured if I messed anything up it would be ok. I installed Ubuntu (I made it so I could dual boot with windows 2000) and after the installtion everything looked fine, but I am unable to connect to my internet. I have internet through my cable company. I tried going into windows 2000 and I am unable to get into my internet there as well.

Ubuntu knows that I have a networkcard because I ran ifconfig eth0 and it shows up. I know that the ethernet cord works because I am using it right now on my laptop. Also, when I am in windows it shows that I have a connection and packets are being sent, but when I try to open a browser it says I have no connection.

What are something that I can do to get the internet to start working again.

Is the driver software installed for Ubuntu and Windows2000?

Is this a desktop computer?  Many operating systems will detect an ethernet card, but in some cases, the driver software may need to be installed.

I think I found the driver, but to be honest I have no clue how to download it through Ubuntu. I tried reading the installation instructions, but none of it worked.

I have the drivers for Windows so I do not know why it is not working there too.

What version of Ubuntu?  Just curious...

9.04 Desktop

Use THIS set of instructions, and see what's in the /etc/network/interfaces file.

[sierradawes]

I am in root and type /etc/network/interfaces and it gives bash: /etc/network/interfaces: Permission denied

[Aegis]

OK, typing that attempts to run the file.  We need to read and edit the file.  Read it first.  Try the command:

cat /etc/network/interfaces

[sierradawes]

Ok I did that and it comes up with

auto lo
iface lo inet loopback

I guess that means it is not saying that my eth0 is avalible. The link did not say what to do it something was not listed.

btw thank you very much for your help.

You're welcome.

I'm not as knowledgeable as I'd like to be, but we'll take it a step at a time.
