![Ubuntu 19.10 未找到 WiFi 适配器](https://linux22.com/image/1067875/Ubuntu%2019.10%20%E6%9C%AA%E6%89%BE%E5%88%B0%20WiFi%20%E9%80%82%E9%85%8D%E5%99%A8.png)
我花了很长时间在谷歌上搜索并尝试修复 Zenbook 上的这个问题,但仍然没有解决。这一切都始于 Windows 10 上的 Wi-Fi 突然消失,但适配器继续在设备管理器中显示为正常工作。我已回滚到保存点 - 但它没有帮助,重新安装 Windows - 仍然没有 Wi-Fi。
然后我删除了 Windows 并安装了 Ubuntu 19.10。安装期间没有网络,启动后我看到未找到 Wi-Fi 适配器。但是:

系统检测到适配器时会不会是硬件问题?没有注意到笔记本电脑内部有什么异常。还尝试断开电池并再次打开——没有帮助。我不知道还能做什么,希望得到帮助。
更新。突然发现,也没有找到蓝牙适配器。它们与 Wi-Fi 有某种关系吗?
答案1
如果你无法在 Windows(即使重新安装)和 Linux 中使用 Wi-Fi 适配器,那么这很可能是硬件问题。如果你可以手动断开 Wi-Fi 适配器,那么你可以更换它。只需购买几乎相同的 Wi-Fi 适配器并代替它。
系统可以检测到工作不正常的硬件,但无法像您这种情况那样使用它。在具有不同元件的不同电路中拥有大量功能,硬件可以部分工作。元件也可以并行启用,因此硬件模块仍然可以工作,但不能按要求工作。它可以被检测到,但无法按照驱动程序的指示执行操作。
答案2
如果您可以通过其他方式(有线或 USB 网络共享)访问互联网,您可以尝试安装较新的iwlwifi
驱动程序:
sudo apt update
sudo apt install git build-essential
git clone https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/backport-iwlwifi.git
cd backport-iwlwifi/
make defconfig-iwlwifi-public
sed -i 's/CPTCFG_IWLMVM_VENDOR_CMDS=y/# CPTCFG_IWLMVM_VENDOR_CMDS is not set/' .config
make -j4
sudo make install
sudo modprobe iwlwifi
参考:AskUbuntu 主题。
答案3
在我的 Asus Zenbook UX5401 上,安装了 ubuntu 22.04.1 LTS,今天更新到内核 5.15.0.50-generic 后几乎可以完美运行。
