我知道，那应该与 Wifi 适配器有关，但我一点头绪都没有。有时我的 wifi 连接持续很长时间，有时不稳定，网络应该每 2 分钟重启一次

我只能看到以下 pcieport 0000:00:1c.4: AER: 设备 [8086:9d14] 错误状态/掩码=00001000/00002000

似乎是内核问题。旧内核 5.4.0-52-generic 也给我带来了同样的问题。我已将 Ubuntu 20.04.1 升级到内核5.6.0-1032-oem，dmesg 日志目前很清晰

sudo apt install linux-headers-oem-20.04 linux-oem-20.04 --fix-missing
