Leap 42.1 = NetWork card does not work

My network card does not work with Leap 42.1
When I turn on my PC I see the LED on where the network cable is connected.
But when the OpenSuse rises, the LED is off and do not have access to the network.
Before installing Leap 42.1, I was using OpenSuse 13.2 and the network was working normally
Wed I can do to solve this problem?
Tanks in advance;

Sorry, but I do not know why the network card returned to work.
Please, administrators erase this thread
Thank you
