Ubuntu: Can't enable my wifi on Lenovo G40-30 laptop



Question:

I've searched for an answer by myself for a very long time but nothing helped me. I can't turn my wifi on (although it works perfectly with Windows) and I can't use ethernet for other reasons. I've already tried rfkill and "create a shortcut.." but neither of those worked for me.. I'm using a Lenovo G40 with Windows 10 as Primary OS and Ubuntu 14.04 as a dual boot.

For both commands.. (ifconfig and lspci -knn | grep Net -A2 ) ..the output was:

02:00.0 Network controller [0280]: Qualcomm Atheros QCA9565 / AR9565 Wireless Network Adapter [168c:0036] (rev 01)      Subsystem: Lenovo Device [17aa:4026]      Kernel driver in use: ath9k  

Here's the output for rfkill list

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    3: hci0: Bluetooth        Soft blocked: no        Hard blocked: no  

for sudo dmidecode | grep "System Information" -A8

 System Information          Manufacturer: LENOVO          Product Name: 80FY          Version: Lenovo G40-30            Wake-up Type: Power Switch          Family: IDEAPAD  


Solution:1

If you have no other connection to internet, you can temporarily enable wifi by

sudo modprobe -r ideapad_laptop  sudo rfkill unblock all  

To make it permanent run

sudo add-apt-repository ppa:hanipouspilot/ideapad-laptop  sudo apt-get update  sudo apt-get install ideapad-laptop-dkms  

This will install ideapad_laptop with my patch for this laptop. The patch has been accepted upstream but did not reach all Ubuntu kernels.
