rtw_8822ce无线网卡Ubuntu系统下频繁断连问题求助

大家好，最近几个月我被无线网卡的问题折腾得够呛！之前只是几周偶尔出现一次，重启一下就能搞定，但现在每隔几分钟就出状况，直接让我的设备WiFi彻底没法用了。自己查了好久都没找到解决办法，有没有大佬能帮忙支个招呀😂

系统背景 #

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

具体问题 #

• 有时WiFi会突然断开，打开系统设置后完全检测不到任何网络
• 有时候能检测到网络，但尝试连接时一直失败
• 还有些时候显示已经连上网络，但实际上根本没有互联网访问权限

dmesg日志输出 #

运行dmesg后，我得到了以下关键日志：

除此之外，有时候dmesg还会出现其他错误，比如：

• mac power on failed
• failed to poll offset something something

还有频繁出现的PCI总线超时错误：
