我最近从新雇主那里得到了一台 XPS 13 9310，并将其操作系统替换为 Ubuntu 20.04。
我无法让 WiFi 正常工作 - 有时适配器会出现并工作一段时间，有时则不会。
以太网似乎运行良好。
我通过谷歌搜索找到的所有帖子都有类似的问题，但并不完全相同，而且它们的解决方案对我来说不起作用——它们似乎大多使用旧版本的 Ubuntu，并通过升级到更高版本或最新内核来解决问题。我试过 Ubuntu 21.04 和 18.04，但什么也没改变。
我还遇到了屏幕随机冻结、鼠标和键盘停止响应以及被迫关闭电源然后再打开的问题。我不知道这是否相关。
以下是可能有用的各种命令的输出：

答案1
这是旧内核的一个已知问题。我可以通过安装较新的内核apt install linux-image-generic-hwe-20.04-edge或apt install linux-image-5.13.0-1009-oem
你可以使用以下命令查看可用内核的完整列表apt list linux-image*
确保linux-firmware也是最新的，或者尝试最新的wget https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/iwlwifi-QuZ-a0-jf-b0-63.ucode -O /usr/lib/firmware/iwlwifi-QuZ-a0-jf-b0-63.ucode
您还可以尝试其他方法：
- 使用以下方式更新设备上的固件
fwupdmgr refresh --force && fwupdmgr upgrade - 在 /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf 中更改
wifi.powersave为2 - 尝试使用内核命令行选项，例如
pcie_aspm=off，完整列表可在此处获得：https://www.kernel.org/doc/html/v5.11/admin-guide/kernel-parameters.html sudo add-apt-repository ppa:canonical-hwe-team/backport-iwlwifi && sudo apt-get update && sudo apt install backport-iwlwifi-dkms
