我想连接到建议使用 /etc/wpa_supplicant/wpa_supplicant.conf 的 wifi：
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
ap_scan=1
network={
ssid="####"
proto=RSN
key_mgmt=WPA-EAP
pairwise=TKIP
auth_alg=OPEN
eap=PEAP
identity="####"
password="####"
ca_cert="/etc/ssl/certs/cacert.org.pem"
phase2="auth=MSCHAPV2"
}
我已经评论了 proto 和 key_mgmt，因为我找不到问题
这是我的 iwconfig 的相关部分：

ifconfig 如下：

这是我第一次使用没有 GUI 的操作系统，我仍然使用 HDMI 连接的显示器，因为我没有互联网，所以无法安装任何东西。如果您需要任何进一步的信息，请告诉我！

关注这个官方维基页面：

我确认这些说明刚刚在运行官方 ODROID 最小 Ubuntu 16.04 映像的 ODROID C1+ 上对我有效。
我确实遇到了问题，因为我使用的是臭名昭著的 Edimax 7811UN USB WiFi 加密狗。它需要两个额外的步骤：
1）我必须按照本主题中的最后一篇文章，在 .service 文件中的 wpa_supplicant 行末尾添加 -D wext：
https://www.raspberrypi.org/forums/viewtopic.php?f=28&t=104856
2) 另一个步骤是臭名昭著的 Edimax 省电问题。
如果您有一个具有相同芯片组的 WiFi 适配器，您可能需要对其进行故障排除/修复。
