我正在使用联想 ThinkPad Edge 14 0578
好吧。我犯了一个非常愚蠢的错误，删除了许多重要的软件包（导致无法连接到网络，无论是有线还是无线）。因此，我别无选择，只能使用 DVD 重新安装。
重新安装时，我插入了 LAN 电缆，它显示可以访问网络。但是，重新安装后，有线连接正常，但无线连接不正常。
和ifconfig wlan0 up
wlan0: ERROR while getting interface flags: No such device
和iwconfig
eth0 no wireless extensions.
lo no wireless extensions.
但实际上，该芯片是存在的。

答案1
基本上，这听起来像是驱动程序/模块问题。您可以使用以下方法确定哪个模块与您的无线组件相关联：
lspci -vvnn
加载此模块：
modprobe [module name]
您可以在 中设置启动时加载的模块/etc/modules。将您的无线模块添加到此文件，然后重新启动。
