最近从 ubuntu 19.10 更新后,我重新启动了 PC。重新启动后,我发现没有可用的 wifi 适配器。要手动安装 wifi 适配器,我尝试了以下命令:
sudo lshw -C network
它产生以下输出
*-network

为了调查有关无线 PCI 的详细信息,我还尝试了以下操作
lspci -nnk | grep 0280 -A2
这表明,
00:14.3 Network controller [0280]: Intel Corporation Device [8086:02f0]
Subsystem: Intel Corporation Device [8086:0034]
Kernel driver in use: iwlwifi
我不知道该做什么或者如何安装/安装哪个驱动程序。
顺便说一句,我找不到无线设备的制造商。
