PC 最近升级到 23.04和 Mate 桌面。Mate 没有显示 Wifi 图标。重新启动进入 Ubuntu Gnome 桌面,显示并连接到 USB Wifi 适配器:

重新启动 Mate 后,它仍然没有出现在网络或任务栏中。虽然硬件出现了:

然后 Ubuntu 显示更新已准备就绪,所以我安装了它。Wifi 仍然没有显示。因此重新启动进入 Gnome...然后它没有显示在那里。因此在升级和不升级之间,Wifi 在 Gnome 中停止工作,在 Mate 中仍然无法工作。
有人知道如何让 Mate 和 Gnome 再次识别 Realtek USB Wifi 硬件吗?
谢谢!
PS:搜索时 Askubuntu 上的所有其他链接都比较旧,似乎不适用于 23.04。

您的 0bda:a881 设备不是 8812au 设备;它是 8821au。让我们安装正确的驱动程序。通过以太网、网络共享或任何可能的方式建立有效的互联网连接:
sudo apt update
sudo apt install --reinstall git dkms build-essential bc
git clone https://github.com/morrownr/8821au-20210708.git
cd 8821au-20210708
sudo sh install-driver.sh
重启。一切就绪。
