我又对 aptitude 做了些奇怪的事情（别再捣乱了）。看来我可能卸载了无线网络适配器的驱动程序（运行时它不显示，运行时ifconfig它被标记），所以我当然无法连接到任何无线网络。但是我也无法通过以太网连接到互联网。或者更准确地说，我无法连接到大多数互联网。UNCLAIMEDlshw -class network
使用有线连接时，如果我尝试 ping 8.8.8.8，就会被Destination Host Unreachable拒绝。如果我打开网络浏览器，我可以访问 Google 及其所有服务，并且可以执行网络搜索。但是我无法访问任何其他网站。
最令人沮丧的是，我无法查找更新或重新安装无线设备驱动程序。
ifconfig以下是该机器的输出：
