Network works during installation, fails on installed system.

[Andreas Gazis]

I am using the following system:

K7N2GM2 mboard from MSI (http://www.msi.com.tw/program/products/mainboard/mbd/pro_mbd_detail.php?UID=619)

with an Athlon XP 1700+

and a Cnet PRO 200 PCI network card (the onboard card is disabled from the BIOS).

The machine is connected via the ethernet plug to a Thomson Speedtouch 530 ADSL modem which lives at 10.0.0.138

I have tried migrating from Debian Sarge to Ubuntu.

I tried the desktop CD images (liveCD) for Ubuntu and Kubuntu as well as the server CD image, all version 6.06-i386.

During the liveCD booting, all the hardware gets detected fine and I have succesfully configured the network (both DHCP and static) using the Gnome GUI or manually through editing /etc/network/interfaces.

I assume it also works fine with the curses based server installer, since it doesn't come up with an error when trying to use DHCP.

As soon as the installation is complete and the system is rebooted from HD, the network fails. The card seems to be fine and I can configure it manually to a static IP but it refuses even to ping the router (Destination host unreachable). The /etc/network/interfaces file is identical in both cases but the network is down.

Apart from the live CD booting, the card also works fine on Windows XP and Debian Sarge. I have submitted a thread in the forums under:

http://www.ubuntuforums.org/showthread.php?t=199688

I am icluding the output of ifconfig -a for the CD and the HD booting as well as lspci below:
