About Lenovo Super-loaded Ubuntu system cannot turn on the wireless hardware switch solution

First, the problem description

I use Lenovo Super-YOGA2 Pro, the default load into the WIN8 system, but when loaded into Ubuntu dual system, there will be wireless hardware switch off problems, of course, can not be connected to the network.

Use

Rfkill List all

The following prompt will appear

0 : ideapad_wlan:wireless lansoft blocked:nohard blocked:yes 1 : Ideapad_bluetooth:bluetoothsoft blocked:nohard blocked:yes 2 :p hy0:wireless lansoft blocked:nohard blocked:no 3 : Hci0:bluetoothsoft blocked:yeshard blocked:no

You can see that the priority of the Ideapad_wlan hard blocked default is yes, that is, Ubuntu default off the hardware WiFi switch, and ultra-YOGA2 pro such as only software switch WiFi, no hardware switch start, So it caused the problem that WiFi could not be opened.

Second, problem solving

From the display list of the wireless module, we can see that the 2 WiFi module is hardware and software can be started, so as long as the previous default module moved out; Use the command:

sudo modprobe -R ideapad_laptop

Move out of the IdeaPad Wireless module, then use the command to view:

Rfkill List all

The following tips:

That is, the WiFi module works fine, but each time you restart the Ubuntu system to re-move the module, you can set the command to boot from boot, by adding commands in the/etc/rc.local file.

#!/bin/SH-e## rc.local## This script was executed at the end of all multiuser runlevel.# make sure that the script would"Exit 0"On success or any other# value on error.## in order to enable or disable this script just change the execution# bits. # # By default this script does nothing. #因为使用的是非管理员登录, so when you execute the sudo command, enter the password to automate, #此处假设用户密码为123, and the command must be run before exit 0. If the file does not have permission to modify # Use before modifyingchmodcommand to modify the permissions can! Echo "123"|sudo modprobe-R Ideapad_laptopexit0

After booting the system will automatically execute the change script file, complete the WiFi module automatic removal operation.
