[Ethernet Interface] Ethernet interface can't work properly

I installed  synergy, but I don't cancel "Synchronize screen savers".

That why cause my ethernet interface can't work properly.

Solution :

My Hard Disk have dual OS.

I switch to windows 7.

cancel "allow computer shutdown this device to save power", then switch Ubuntu 10.04 again.

The interface work properly now.
