我最近在 Dell Inspiron 3551 上安装了 Linux Mint，除了 WiFi 网络适配器外，一切正常。我的笔记本电脑没有以太网端口，必须严重依赖 WiFi。现在我尝试安装驱动程序，在使用命令“lspci”后，它显示 WiFi 网络适配器存在。然而“lshw”显示“该设备尚未被认领”。我如何领取该设备？或者更确切地说...我如何启动我的 WiFi 适配器？
我使用了以下命令：
lshw -c net

答案1
缺少内核模块 (ath9k) 或 wifi 卡所需的固件。较新的内核应该有此模块，以支持您的 wifi 卡。
modinfo ath9k将显示内核是否可以提供有关此模块的信息。
find /lib -name ath9k.ko向我们显示该模块是否位于磁盘上的任何位置。
