HP Probook 455 - brak połączenia LAN

[tkpsmr]

Witam,
Zamierzam zainstalować Ubuntu na moim laptopie, jednak przy uruchomieniu z Live CD nie mogę się połączyć z internetem (połączenie ethernetowe w akademiku). Mam HP Probooka 455 i zauważyłem że gdy uruchamiam Ubuntu to przycisk którym mogę wyłączać i włączać wifi w laptopie zmienia kolor na czerwony, co normalnie znaczy że wyłączam wifi. Naciskanie go nic nie daje (dla odmiany przycisk wyciszania znajdujący się obok działa normalnie).
Ubuntu cały czas szuka połączenia, i co raz zmienia status sieci na rozłączono.
Dodam że na windowsie 7 wszystko działa bezproblemowo.

Szukam rozwiązania od kilku dni i nic nie mogę znaleźć. Proszę o pomoc.

Po wpisaniu komendy

rfkill list

wyświetla mi się coś takiego

Kod: Zaznacz cały

ubuntu@ubuntu:~$ rfkill list
0: phy0: Wireless LAN
	Soft blocked: no
	Hard blocked: no

Nic to nie dało.
