Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free.

I just got a new laptop and installed Ubuntu on it. Wi-fi worked fine on Windows 8, but now it says that it's disabled by a hardware switch. rfkill unblock all did nothing. Many people have suggested installing something, but there's no ethernet port. Tried using a USB dongle, that's blocked too.

Do I have to go spend $25 on an ethernet to USB adapter I'll only use once, or is there another way?

Here's the output of rfkill list all:

0: ideapad_wlan: Wireless LAN
        Soft blocked: no
        Hard blocked: yes
1: ideapad_bluetooth: Bluetooth
        Soft blocked: no
        Hard blocked: yes
2: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: no
7: hci0: Bluetooth
        Soft blocked: no
        Hard blocked: no

"hard lock" actually means what it says: you have a switch on your machine itself, in the bios or on your keyboard to lock wifi. –  Rinzwind May 30 '14 at 7:34
    
@Mitch Lenovo Yoga 2 11.6". –  Cheezey May 30 '14 at 20:55
    
@Rinzwind There's no switch. There is a keyboard key that soft blocks it, and it's off. And I enabled it in the BIOS. –  Cheezey May 30 '14 at 22:12

Look around your laptop.

There is no hard switch in that model. That is the problem. –  Pilot6 Jun 4 at 18:28

This has been fixed for Yoga in kernel 3.16.

For Ubuntu 14.04 just upgrade your kernel to 3.16 by

sudo apt-get install linux-generic-lts-utopic

or to 3.19 by

sudo apt-get install linux-generic-lts-vivid
