我正在使用带有 ryzen5 5625u 的 pavilion。我已经尝试过了这个答案并根据另一个答案禁用了安全启动。我也运行了，sudo systemctl restart network-manager但它说重启失败。我还去了软件和更新以安装其他驱动程序，但没有其他驱动程序可以安装。
它说没有 wifi 适配器
输出 cat /etc/modprobe.d/iwlwifi.conf
cat 命令的输出
这是输出ip a # check if you can see wireless card

和输出lspci -knn | grep Network -A3 # This shows card name and driver, if in use.

我不确定这是否有帮助，但是我使用的是 22.04.1 服务器。我使用的是内置 Wi-Fi 卡，并且已连接。但是在 GUI 中，根据图标和下拉菜单，它没有显示我正在使用 Wi-Fi。这是我的界面的样子：

接口 wlp2s0 是我的 wifi 卡。也许可以使用 $ ifdown 和 $ ifup 来查看是否适合您的情况。（如果您还没有安装 net-tools，请安装 sudo apt install）
希望这可以帮助。
