랩탑의 Lenovo Ideapad Y580 (사전 설치된 Windows 7 Home Premium 64bit에서 구입)의 wifi에 문제가 있습니다. Win7을 제거한 후 Ubuntu 13.10 64bit (일반 유선 인터넷이 작동하는 곳)를 설치하면 Wi-Fi가 작동하지 않습니다!
하드웨어 스위치에 의해 무선 기능이 비활성화되었습니다.
rfkill 모두 나열
martin@martin-Y580:~$ rfkill list all
0: ideapad_wlan: Wireless LAN
Soft blocked: no
Hard blocked: no
1: ideapad_bluetooth: Bluetooth
Soft blocked: no
Hard blocked: no
2: phy0: Wireless LAN
Soft blocked: no
Hard blocked: yes
BIOS를 확인했는데 무선 카드가 활성화되어 있습니다.
Fn + F5가 작동하지 않고 컴퓨터의 외부에 물리적 스위치가 없으므로 여기에 물었습니다.
rfkill unblock all
소프트 블록 만 변경하고 sudo ifconfig wlan0 up
이것을 보여줍니다 : SIOCSIFFLAGS: Operation not possible due to RF-kill

일부 사양 :
