我正在使用带有 USB WiFi 模块 4 的 Odroid XU4 和 Ubuntu 16.04 的官方 Odroid 发行版。
如果我sudo rfkill unblock wifi在终端中输入内容，一切都会正常工作，但我希望这台机器能够无头且不受束缚地运行，所以这不是一个解决方案。
我也尝试过将 unblock 命令添加为服务或添加到 /etc/rc.local。但都没有成功。
来自系统日志的一些可疑行：
NetworkManager[678]: <info> [1525808228.9431] rfkill0: found WiFi radio killswitch (at /sys/devices/platform/soc/12110000.usb/usb1/1-1/1-1:1.0/ieee80211/phy0/rfkill0) (driver rt2800usb)
NetworkManager[759]: <info> [1525809316.1008] (wlan0): using nl80211 for WiFi device control

NetworkManager[759]: <info> [1525809321.7114] manager: WiFi now disabled by radio killswitch
据我所知，XU4 没有用于禁用 WiFi 的硬件开关。

答案1
我使用显示器和键盘登录，发现 GUI 中有一个未选中的“启用 WiFi”菜单项。检查该菜单项似乎解决了问题。nmcli r wifi on如果以后其他人遇到这个问题，我似乎也可以在命令行上使用 来完成此操作。
