我在 Ubuntu 15.04 上使用华硕笔记本电脑 X450JB。我的 WiFi 无法使用。
- 我尝试通过顶部栏 -> 启用 WiFi 来启用它,但是不起作用。
- 我尝试通过Fn+启用它F2,但也不起作用。
- 我尝试了几个操作系统:Ubuntu 15.04,Fedora 22,CentOS 7,但都没有用。
- 我尝试安装 Windows 10(未激活),WiFi 开箱即可使用。Fn+F2也能正常工作。
我尝试了其他页面上的几条建议:
$ sudo rfkill unblock all
不起作用。- 进入睡眠模式(Fn + F1)然后唤醒不起作用。
echo "options asus_nb_wmi wapf=4" | sudo tee /etc/modprobe.d/asus_nb_wmi.conf
对我来说没用。我从wapf=0
一直试到wapf=4
,都没用。
我刚刚安装了全新的 Ubuntu 15.04,以下是我的硬件的一些情况:

答案1
您使用的平台驱动程序有误acer-wmi
。
如果你没有手动启动它,这肯定是一个错误,错误地检测了笔记本电脑供应商。这应该由
ubuntu-bug linux
解决方法是,您可以通过以下方式禁用此驱动程序
sudo modprobe -r acer_wmi
