解決y7000筆記本ubuntu下wifi無法連接問題

 

查看wifi與藍牙硬件開關，發現ideapad的硬件模塊都是關閉的

rfkill list all

 

打開終端

輸入

sudo gedit /etc/rc.local

寫入以下內容 進行保存

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "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.

echo "123" |sudo modprobe -r ideapad_laptop
exit 0

 

為了保證重啟生效，需要給予權限 終端輸入

sudo chmod 777 /etc/rc.local

然后輸入

reboot

重啟后發現wifi正常使用，但是信號遠比WIN要差切容易斷 

解決方案

sudo apt-get install git build-essential linux-headers
git clone https://github.com/lwfinger/rtlwifi_new.git
cd rtlwifi_new
make
sudo make install
reboot
