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

重新启动到 Mate 后,它仍然没有显示在网络或任务栏中。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。无线网络仍然没有显示。所以重新启动到 Gnome...然后它就没有显示在那里。因此,在升级和不升级之间,Wifi 在 Gnome 中停止工作,并且在 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 搜索期间 Askubuntu 上的所有其他链接都较旧,似乎不适用于 23.04。
