我正在使用 Kubuntu 23.04，过去几周一直在尝试修复此问题。您可以想象，我在这里和其他地方阅读了大量帖子，但到目前为止还没有成功。
我的 wifi 总是断开连接，然后 SSID 从列表中消失，然后重新出现并重新连接。然后重复这个过程。我拥有的其他设备都没有这个问题，所以这不是网络/路由器的问题。
到目前为止我已经尝试过：
- 关闭省电功能
- 强制 IPV4
- 将无线网卡更换为 Intel AX200
- 更换路由器
- 更改 SSID
- 全新安装
输出iwconfig：

我不确定这是否是某种线索，但当这种情况发生时，SSID 也会从我所有其他设备的 wifi 列表中消失，除非它们已经连接。有时它们也会断开连接，但并非总是如此。
我知道这太多了，但任何帮助都会非常感激。谢谢。
答案1
也许您的路由器每隔很短的时间就会改变频道。其他设备可能有移动数据，并在没有互联网时切换到它。您可以获取路由器上的 IP 地址，并尝试更改路由器的设置，以便它不会如此频繁地改变频道。如果这不能解决问题，那么可能存在另一个与路由器本身无关的问题。如果您想知道如何更改路由器的设置，您必须输入路由器的 IP（例如 192.168.000.1）并输入您的密码。
