dhclient 几秒后断开连接

我一直在与我的 ubuntu 16 lts 服务器的界面作斗争，以便在启动时连接到 wifi。目前，我使用 wpa_supplicant 和 dhclient 进行连接。如果我手动执行这两项操作，则可以毫无问题地连接。当我想从启动时启动这两项操作时，似乎 wpa_supplicant 工作正常，但 dhclient 不行。我已使用以下配置设置了服务：

[Unit]
Description= DHCP Client
Before=network.target

[Service]
Type=simple
ExecStart=/sbin/dhclient wlp58s0 -v
ExecStop=/sbin/dhclient wlp58s0 -r

[Install]
WantedBy=multi-user.target

看起来它加载正常，连接成功，但几秒后就断开了...

系统日志中有更多详细信息，看来绑定没问题

首先，似乎所有事情都有重复的消息。我认为这不正常，我一直在寻找可能的重复进程，但似乎并非如此。

另外，我粘贴了我的网络/接口

allow-hotplug wlp58s0
iface wlp58s0 inet dhcp
wpa-driver wext
#pre-up killall -q wpa_supplicant
wpa-roam /etc/wpa_supplicant.conf
