我最近在 HP probook 655 G2 上全新安装了 Ubuntu 20.04。问题是，起初 wifi 适配器可以工作，但过了一会儿，它说找不到 WiFi 适配器。我重新启动后，wifi 适配器可以工作，但过了一会儿，我又遇到了同样的问题，找不到 Wifi 适配器。
我在 wifi 适配器正常工作和不正常工作时分别运行了 lshw -C network 和 lspci -knn | grep Net -A3; rfkill list。结果如下。
编辑：“未找到 wifi 适配器”下的第 4 个代码块，dmesg | grep iwl 给我一个大错误消息，无法唤醒网卡，不知道我该怎么办。由于我在使用 Windows 时没有遇到这个问题，所以我不认为这是硬件问题。
编辑：我这样做了：sudo apt install backport-iwlwifi-dkms。没有解决问题
Wifi 适配器正在工作
