在 Asus X405U 中安装 Ubuntu 16.04 后 WiFi 无法使用

自从在我的笔记本电脑(Asus X405U)上安装 Ubuntu 16.04 以来,我就看不到 wifi。我尝试了这里找到的几种方法,但仍然没有 wifi。

rfkill list只显示蓝牙,但没有无线。

我安装了 MT7630E-release,但它不起作用。安装后bcmwl-kernel-source也没有改变任何东西。

此外,除了一个名为“未知”的驱动程序并且选择了“使用来自 intel-microcode(开源)的英特尔 CPU 处理器微码固件”之外,我没有其他附加驱动程序。

这是我的 wireless-info.txt:
