安装Ubuntu后无法连接到无线网络
Ubuntu默认关闭了硬件wifi开关,拯救者R720只有软件开关,所以引起了wifi不可用的问题
使用rfkill list all 命令:
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: yes
Hard blocked: no
移除掉ideapad无线模块:sudo modprobe -r ideapad_laptop
再次使用rfkill list all命令查看会发现ideapad模块已经不在了。
永久移除:
将ideapad模块列入黑名单
1、创建/etc/modprobe.d/ideapad.conf文件:
sudo touch /etc/modprobe.d/ideapad.conf
2、编辑ideapad.conf文件:
sudo gedit ideapad.conf
3、在ideapad.conf文件中添加:
blacklist ideapad_laptop
4、关闭并保存ideapad.conf文件,移除ideapad_laptop设备:
sudo modprobe -r ideapad_laptop
5、重启Ubuntu之后,wifi正常连接
