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？

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
