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
