无线已被硬件禁用

我尝试在笔记本电脑上使用 wifi，但出现一条消息“无线已被硬件禁用”

我尝试更换物理开关，但没有解决问题。也使用过 fn，但硬件问题没有得到解决。

我的硬件是

我的笔记本电脑是 Philco PHN14005，我使用 Ubuntu 14.04 64 位。

我该如何修复这个 wifi 硬件？

在我这样做之后

 carlos@carlos-pc:~$ lsmod | grep -e wmi -e laptop

使用此命令后

答案1

sudo apt-get purge bcmwl-kernel-source然后sudo apt-get install firmware-b43-installer重启。如果重启后不起作用，请添加lsmod | grep -e wmi -e laptop

答案2

你可以尝试下面的命令吗

sudo rmmod -f dell-笔记本电脑

sudo rfkill 解除所有阻止

检查是否有效

答案3

我认为这可能和你的问题类似。

无线显示为已禁用，我该如何让它工作？

解决方案是：

sudo rm /dev/rfkill && sudo reboot
