我几个月前安装了 Ubuntu 22.04（内核 5.15.0.41.44），我的 wifi 没有问题。
过去 3 天发生了一些事情。当我启动笔记本电脑时一切正常，但 3-5 分钟后，设备断开 Wi-Fi 连接然后重新连接，并持续尝试一段时间，最后连接丢失。
当我连接到手机的 Wi-Fi 并且距离很小的时候，连接很稳定。
我几乎尝试了所有方法，我重启了模块，重启了网络管理器，关闭了无线省电模式，更新到内核 5.19.0然后降级为5.18.15大约 15 分钟后问题就解决了，但又开始出现同样的问题。我真的很沮丧，现在我不知道安装另一个 wifi 驱动程序是否有帮助。我正在使用“Realtek-RTL8821CE”。我见过许多类似的问题，但没有任何解决方案有帮助。
最近，我遇到了一些问题。有些包无法升级，它们被保留了下来。我尝试单独安装它们后，sudo apt install package-name仍然出现此问题：我估计错误是由我的 wifi 适配器引起的。谢谢您的时间。
