我有时会遇到网络问题（无信号、上传速度慢等），我想我最终可以重现它们：我注意到我的 wifi 和外部 HDMI 端口/显示器之间存在奇怪的行为。
有问题的配置：
- 外接显示器插入笔记本电脑的 HDMI 端口并打开显示器。
没有问题的配置：
- 外接显示器插入笔记本电脑的 HDMI 端口并关闭显示器。
- 外部显示器插入 HDMI 加密狗并且显示器已打开。
- 外接显示器未插入（仅内置显示器）
一旦我更改配置，问题就会开始和停止 - 例如：立即用上传速度测试仪进行测试。
老实说，我无法想象是什么导致了这种情况。幸运的是，我仍然可以完美地使用我的 USB-C 转 HDMI 适配器，但如果这个问题能得到解决，那就太好了。（如果我没有“看到鬼影”）

答案1
不是一个完整的答案，但我也面临同样的问题。我尝试减少正在使用的端口数量，但问题似乎出在 HDMI 电缆上。互联网上有些人建议升级到更好的电缆，因为低质量的电缆可能会造成干扰。此外，我尝试更改内核，我注意到当我从 20.04 移动到 22.04 时出现了这个问题。我目前正在使用5.15.0-53-generic，与较新的内核相比，它似乎更稳定。
