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 There's no switch. There is a keyboard key that soft blocks it, and it's off. And I enabled it in the BIOS.

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

  • Can there be a reason why the wifi may again stop working after an hour.

  • @RED Do you have exactly same wireless adapter? If not, ask another question. This answer does not relate to all adapters.

Look around your laptop.

  • There is no hard switch in that model. That is the problem.

I had the same problem. After trying many different suggestions, I found out that my wifi have been turned off by the "Radio on/off" key on my keyboard (usually having an antenna or radio tower symbol on it; on Dell laptop, Fn+F2 key-combination). I see that "MUY Belgium" has suggested that, too; I would up-vote his answer, if I had enough reputation score.
