I'm writing this answer on my WiFi connection. Ethernet cable is disconnected. I have applied last tip by Jeremy and wireless network works. During update installation some errors occured (E: gconf2: dependency problems - leaving triggers unprocessed -> i should to be afraid?) and when I closed error window i saw information about not all updated was made. But i've rebooted computer. When the machine wakes up, i opened update manager again and repeat process. I had warning about two broken packages but this time update process finished without error communicates. Once again reboot, and WiFi connection is OK.

Thank you JeremyB, you saved my life !
