how to restore ubuntu to original point


after i first installed ubuntu, my network card worked just fine. but after i made some change to my system, now ubunta can not detect the network card ( no eth1 when i do: iwconfig).
so i wanna know if there is any way i can discard all the change and restore ubuntu to its original status as if restore to original factory configuration in windows.

Ubuntu (Linux in general) makes it very much your own responsibility to have back-ups of at least the most important configuration files. There simply isn't anything like a "system restore point".
However, in this case, you could also try editing the files manually. The most relevant ones should be /etc/hosts, /etc/resolv.conf and /etc/udev/xx-network.

Try the "Repair a broken system" from the Install menu before you reinstall. It may work for you.

You should first check the output of sudo lsmod to find out whether the driver is still loaded or whether it has disappeared; I have just re-read your post and it is more likely driver related than a matter of configuring the details. And yes, try AuroraC's suggestion as well. If you didn't install the driver manually, that may be the most convenient way of getting things back in working order.

By the way, it would be helpful if you could tell us what it is exactly that you did that made the network drop out.

I learned a lot from installing, reinstalling, reinstalling, reinstalling & not giving up. I went from a "know nothing noob" to a Linux Certified Professional.
