I am having a problem getting my Dell Optiplex 4500 network card working.

I installed Ubuntu Jaunty using the Wubi installer. I don't know if is contributing to the problem, but there it is.

When it boots and I click on the Network Manager, it shows auto eth0 disabled. I have tried everything I can think of to get it working. (I'm mostly a Windows person, with some AIX and Solaris background.)

The network card works perfectly within Windows, so there shouldn't be any defective hardware. I am really perplexed, as I expected a generic network card to be configured out of the box.

Any ideas what might be wrong?

Could you open an Applicatioons-->Accessories-->Terminal and type:


sudo lshw -C network > network.txt

the above command will pipe all the details of your network card to a text file that you can easily copy to your windows partition. Could you paste the oputput from the command in your next post.

--------------
It seem strange that it won't work. Realtek is a very common piece of hardware.
