Linux（Arch）WPA_SUPPLICANT 服务未在启动时启动

Linux（Arch）WPA_SUPPLICANT 服务未在启动时启动

在我的 Microsoft Surface Pro 6 上设置 Linux“Arch”，安装正常，但 wpa_supplicant 作为服务存在问题。服务已启用，但无法在启动时启动。以 root 身份登录后，“systemctl start wpa_supplicant.service”运行良好。这似乎是时间问题（对我来说），但我无法使用 WiKi 或 Google 来帮助自己。任何帮助都值得感激。

/etc/wpa_supplicant.conf

network={
    ssid="MyWiFi"
    psk=be131c51e250735aab71b89563250cba1e13e513ce53e037cd2351791dd07c52
}

答案1

你没有指定什么时候启动服务，所以启动得太早了；它说“wlp1s0 不存在”，因为该接口在那个时间点确实还不存在。

推荐的方法是使用：

[Unit]
Requires=sys-subsystem-net-devices-wlp1s0.device
After=sys-subsystem-net-devices-wlp1s0.device

这也是库存[email protected]解决问题的方法（您可以简单地使用该单位，而不是自己制作）。
