联想 z570 上的 iwlwifi 被硬件开关禁用

它在 Windows 7 上运行良好。

硬件开关没有被禁用。我来回切换了几十次。wifi 灯从不亮，而且总是显示为硬件已禁用。我安装了最新的更新。

我一直在寻找解决方案，但似乎没有一个对我有用。我尝试删除 acer-wmi。我尝试设置 11n_disable=1。我尝试重置 bios。我尝试使用 rfkill 来解除阻止（仅删除软阻止）。我重启了几十次。grub 加载后，wifi 灯会立即熄灭。

编辑：我有一个 USB edimax 无线网卡。它也显示硬件已禁用（尽管 rfkill 列出为未阻止）。如果我卸载 iwlwifi，USB 网卡可以正常工作。
