rtw_8822ce的Wifi断开问题

Question

因此，我从几个月以来一直面临以下问题。他们从来没有那么麻烦，因为他们只发生了几个星期。那么，一个简单的重新启动就可以了。然而，现在每隔几分钟就会发生一次，这使得我的设备上的wifi完全无法使用。我一个人找不到解决办法。因此，有谁能帮我一下哈？

背景：

OS: Ubuntu 22.04.1 LTS x86_64
Host: ASUS TUF Gaming A17 FA706IH_
Kernel: 5.15.0-60-lowlatency

问题：

Sometimes wifi disconnects suddenly. It also fails to detect any networks when opened from settings.
At other times, it does detect networks, but fails to connect to them.
At times it remains connected to networks without actually having any internet access.

在运行dmesg时，我得到的是：

在其他时候，我在dmesg中也会出现错误，比如: mac on failed或未能轮询抵消某些内容。

我也有很多次这样的经历：

很抱歉忘了提供更新。我确实找到了解决这个问题的办法。几个月前我删除并重新插入了真正的wifi卡。谢天谢地，我没有再面临这个问题了。
