![所有网络接口都消失了](https://linux22.com/image/1175035/%E6%89%80%E6%9C%89%E7%BD%91%E7%BB%9C%E6%8E%A5%E5%8F%A3%E9%83%BD%E6%B6%88%E5%A4%B1%E4%BA%86.png)
我有 3 个以太网接口和一个 WiFi 卡,之前一切都运行良好,直到有一天当我打开它时,它无法调出网络接口。当我运行 ifconfig -a 时,出现的只是我的环回和桥接。上次关闭之前我没有更新任何软件。所有推荐的检查都只出现了桥接和环回,我想知道如何解决这个问题。我正在使用 Ubuntu 16.04.4 服务器。
