自从我升级到 22.04 以来，我的网络适配器就出现了奇怪的现象，它每 30 秒就会断开与 Wi-Fi 的连接并自动重新连接一次。有时，它会拒绝重新连接，我必须禁用右上角的互联网，然后重新启用。每当它拒绝重新连接时，WiFi 图标上就会出现一个小问号，并且每秒journalctl都会充满连续不断的CTRL-EVENT-BEACON-LOSS垃圾邮件。
journalctl这是最后一分钟不断断开和重新连接的副本。

答案1
我花了很多时间来解决笔记本电脑的同一问题。
我确信这对每个人都没有帮助，这是我的特殊情况，在我的 Ubuntu 上自动安装了驱动程序 rtw88_8821ce，并且我遇到了 CTRL-EVENT-BEACON-LOSS 消息和不稳定的连接。
我换了司机这并遵循所有说明，这对我很有帮助。据我所知，Realtek 驱动程序和 Linux 内核之间出了问题
