I don't know why, but after having switched off the computer (by removing the wired cable from the electricity, not only by shuting down), the lan work well now. Something is got in memory even if the computer is switched off but not deconnected from the electricity. There is perhaps a relation with windows, because this bug appears just after restarting from windows.
