我在 Lenovo thinkpad 上安装了 Arch linux。我有Linux 5.13.13-arch1-1。最近，我的无线网络在启动一段时间后就停止工作。使其再次工作的唯一解决方案是重新启动。当我跑步时我得到：sudo systemctl restart [email protected]
Job for [email protected] failed because the service did not take the steps required by its unit configuration.
See "systemctl status [email protected]" and "journalctl -xeu [email protected]" for details.
