你好,我对这个问题有疑问。
我的桌面显示器分辨率很奇怪,所以我修复了一次,然后 Wi-Fi 断开连接,显示“未找到 Wi-Fi 适配器”。首先,当我尝试安装驱动程序时,我通过 Google 了解到固件和模块必须一起安装。但有一个问题。固件似乎已安装,但尝试加载模块时命令不起作用。在这种情况下我该怎么办?
我检查了https://community.intel.com/t5/Wireless/AX200-unable-to-detect-WiFi-Network/mp/1225944由英特尔提供,我发现 46,48,50,53,55,59,62,63,66,67,68,71,72,73.ucode 存在于 /lib/firmware 文件中,但我没有使用 'mokutil' 方法。我试试这个方法可以吗?
或者我寻找其他的想法。
我检查了一下$dpkg -l | grep linux-modules
,目前有和Linuxkernel版本相同的模块。那么,是不是没有安装呢?但是,没有多余的模块。所以,这是问题所在吗?
