我尝试使用 wpa_supplicant 从命令行连接 wifi。
我使用 Ubuntu 12.04.1 和 wpa_supplicant 0.7.3
以下是与我尝试连接的 AP 相关的“iwlist wlan0 scan”的输出：

我使用 wpa_passphrase 创建 psk：
user@comp-name:~$ wpa_passphrase "NetworkName" "Password"
这是 /etc/wpa_supplicant.conf 的内容：
network={
ssid="NetworkName"
psk=3d2e908171ebc0aca77f9cf0d4fd392ff76bb4236fa20a8718f1de4c92d5b81d
}
我调用 wpa_supplicant：
user@comp-name:~$ sudo wpa_supplicant -d -iwlan0 -Dwext -Dnl80211 -c/etc/wpa_supplicant.conf
输出：

有任何想法吗？
答案1
我以前也见过这样的错误信息，但没有明确的解决方案。你可能想尝试以下方法：
读wpa_supplicant.conf(5)。这些示例将让您了解可以尝试的额外网络选项。不要忘记为 加上双引号
psk=。改用
-Dnl80211。看来这是您需要的驱动程序。试验路由器的网络模式（B/G/N）。尝试将其设置为不同的值，因为路由器和无线网卡/驱动程序之间可能存在不兼容的情况。
给兼容无线试试吧。我以前没有亲自用过它，但我读到过它包含一些补丁，可以修复过去遇到的类似问题。
答案2
我在 Gentoo 中通过关闭 NetworkManager 修复了这个问题：
/etc/init.d/NetworkManager stop
当两者都运行时，它可能会与 wpa_supplicant 发生冲突。
答案3
我在 Ubuntu 18.10 上通过以下方式修复了此问题：/etc/init.d/network-manager stop
