最近，在使用 Arch Linux 一个月没有出现任何问题后，ip link停止显示我的无线接口（原来是wlp2s0）。我重新启动了一切——没有神奇的修复。所以我从我的安装介质启动。ip link安装介质上列出了一个无线接口 ( wlan0)，并且连接到我的网络wifi-menu不会出现错误。但 ping google.com 仍然会响应temporary failure in name resolution。
现在有一个奇怪的部分：如果我arch-chroot从媒体进入我的机器（wifi-menu从媒体之后），而不使用wifi-menuchrooting 后，那么它可以让我正确连接到互联网。
以下是一些命令的输出：
lspci -nnk（不是完整的输出，如果您需要更多，请告诉我）
