Ubuntu 中无线已禁用并且无法扫描任何网络

我在笔记本电脑上安装了 Windows 和 Ubuntu。Windows 没有问题。我想我可能在 Ubuntu 上做了一些更新，当我重新启动时，没有 wifi 连接。我搜索了很多，除了更新驱动程序之外什么都试过了，因为我家里没有有线连接。我试过 rfkill unblock，无线上没有软或硬阻止。我检查了网络管理器状态并重新启动了它。但它没有用。这是我的一些信息。如果有人能提供帮助，我将不胜感激。谢谢！

我已经安装了新的驱动程序，但问题仍然存在......

您有一个 RTL8822CE 设备，目前还不支持开箱即用。

通过其他方式获取互联网连接，例如连接到 USB 的手机并以这种方式安装驱动程序：

sudo apt update
sudo apt install git dkms
git clone https://github.com/lwfinger/rtw88.git
sudo dkms add ./rtw88
sudo dkms install rtlwifi-new/0.6

如果 Wi-Fi 不工作，您可能需要将树内模块列入黑名单。
