通过终端 Edimax ew-7811un 错误 ioctl[SIOCSIWENCODEEXT] 连接到 WPA：参数无效

我一直在尝试学习如何连接到我的 WPA 安全无线路由器，但无论我研究多少次，我都找不到此错误的修复方法。我两次收到错误（ioctl[SIOCSIWENCODEEXT]：无效参数），然后收到一长串重复输出，涉及我的设备（wlan0）正忙，然后出现错误，声称我的身份验证错误。我也在笔记本电脑上使用其默认无线网卡尝试过该命令，它返回相同的错误。除此之外，偶尔在运行 wpa_supplicant 命令并得到同样令人失望的结果后，我的 wlan0 设备将被设置为 DOWN。我正在尝试从 Edimax ew-7811un usb wifi 加密狗进行连接。

我的 wpa.conf 文件： /home/me/wpa.conf：

# reading passphrase from stdin
network={
        ssid="######"
        #psk="#############"
        psk=#############################################
}

wpa_supplicant 命令：

sudo wpa_supplicant -D wext -i wlan0 -c /home/me/wpa.conf

接下来我删除了我分配的IP：

sudo dhclient -r

并分配一个新的：

sudo dhclient wlan0

我是通过 eth0 连接到互联网来执行所有这些操作的（如果这很重要的话），但是我已经在 eth0 关闭时测试了这一点。我还多次卸载并重新安装了 wpa_supplicant。我还将我的 wpa.conf 文件放在 /etc/wpa_supplicant 中。

wpa_supplicant 的输出，部分内容已被审查：
