我已经在笔记本电脑上运行 Ubuntu 16.04 一段时间了,突然 wifi 停止工作了。WifiSystem Settings > Network
界面下没有出现。运行sudo lshw -C network
结果如下:
*-network UNCLAIMED

通过谷歌搜索,我了解到这network UNCLAIMED
意味着我的 wifi 卡未被任何模块使用?或者可能缺少驱动程序?这是一个截屏以及System Settings > Software and Updates > Additional Drivers
另外可能值得一提的是,我禁用了安全启动(我不太清楚为什么我这样做,只是在搜索时出现了这个问题dkms
)。任何帮助都将不胜感激!!
