我在 Toshiba Satellite L50-B 上使用 Ubuntu 16.04 已有数月，上周它无法连接到 Wi-Fi。我浏览了互联网并尝试了许多建议的解决方案，但似乎没有一个能解决问题。
总体情况是 Wi-Fi 驱动程序似乎无法正常工作。检查状态栏时，我看到“Wifi 网络 - 已断开连接”，并且通常看不到可用的 Wifi 网络，尽管我的手机已连接到 Wifi 网络。
我的网络控制器是 Intel Corporation Wireless 3160 (rev 83)。我尝试下载驱动程序并将其复制到 /lib/framework，但没有成功。
蓝牙已关闭，所以这应该不是问题。你能帮我吗？
我也运行了modinfo iwlwifi，但结果太长，无法在此处发布。其中一部分（没有别名）在这里：
