Please open a terminal and paste the output of:

$ lspci

$ lsmod

$ ifconfig -a

You might want to use a USB thumb drive to copy the output to and then get it to the forum from a working PC.

If ifconfig -a shows eth0, then your network device is detected but failing to obtain an IP address. Are you using DHCP in your network?

If eth0 is not displayed, then a proper driver for your network card could not be found, the output of `dmesg` might reveal something. You could paste that here as well.
