Hi, I have a new MSI K9MM-V motherboard (AMD 64 X2) with a 4000+ dual AMD cpu. There were no indicated problems with the installation. The onboard network interface eth0 works fine when I a browsing the Internet. When I try to copy files over the LAN (scp, ftp, samba), the interface stops working. When I used Ethereal, it hung on a retransmit request repeatedly. I don't find any issues in Google except the MTU size. The drivers supplied with the MB are pretty old - up to FC 3. I am using the drivers supplied with FC 8 How can I determine if It is * Configuration * Drivers * Defective mother board? Thanks Mike Johnston
