wpa_supplicant没有连接“ioctl ：无效参数”错误！
Ubuntu Server 12.04安装在我的桌面系统上（文本模式，没有X-Window可用），我没有连接有线以太网，只有无线网络可用。 我使用TP-Link TL-WN723N USB无线适配器连接到无线网络。
起初，尝试使用iwconfig进行连接，但发现它无法用于连接到WPA2安全网络！ 在fisrt， iwconfig显示：
lo no wireless extensions. eth0 no wireless extensions. wlan0 IEEE 802.11bgn ESSID:off/any Mode:Managed Access Point: Not-Associated Tx-Power=20 dBm Retry long limit:7 RTS thr=2347 B Fragment thr:off Power Management:off
和sudo iwlist wlan0 scanning显示：
wlan0 Interface doesn't support scanning : Network is down
在运行sudo ifconfig wlan0 up ， sudo iwlist wlan0 scanning显示：

我安装了wpasupplicant来连接到使用WPA2保护的无线网络。 但是使用这个包有一些问题：
我尝试按照此答案中的说明操作
wpa_passphrase 'MYESSID12345' 'MYPASSWORD$1234567' > CONFIG_FILE
在上面的命令之后，我编辑了CONFIG_FILE（ /etc/wpa_supplicant/wpa_supplicant.conf ），因此它包含：
network={ ssid="MYESSID12345" scan_ssid=1 key_mgmt=WPA-PSK psk="MYPASSWORD$1234567" proto=RSN WPA pairwise=CCMP TKIP group=CCMP TKIP #psk=1234567890abcdef1234567890abcdef1234567890abcedf1234567890abcdef }
接下来我运行wpa_supplicant -iwlan0 -c/etc/wpa_supplicant.conf -Dwext -dd 。 结果是在stderr出现以下错误：
ioctl[SIOCSIWENCODEEXT]: Invalid argument ioctl[SIOCSIWENCODEEXT]: Invalid argument ioctl[SIOCSIWENCODEEXT]: Invalid argument ioctl[SIOCSIWENCODEEXT]: Invalid argument
和stdout是：

在最后一个命令之后， wlan0变为DOWN，我必须再次使用sudo iwconfig wlan0 up命令来完成它。 此外，我尝试删除network-manager包基于评论说这可能解决问题，但没有成功。
还尝试编辑wpa_supplicant.conf1文件，如下所示：
对于wpa_supplicant.conf尝试＃1
network={ ssid="MYESSID12345" #psk="MYPASSWORD$1234567" psk=1234567890abcdef1234567890abcdef1234567890abcedf1234567890abcdef }
对于wpa_supplicant.conf尝试＃2
network={ ssid="MYESSID12345" scan_ssid=1 key_mgmt=WPA-PSK #psk="MYPASSWORD$1234567" proto=RSN WPA pairwise=CCMP TKIP group=CCMP TKIP psk=1234567890abcdef1234567890abcdef1234567890abcedf1234567890abcdef }
首先，如果你的路由器设置为使用WPA2-AES而不是TKIP，我认为你会有更好的运气。
其次，我相信你正在走这条漫长而复杂的路线，而这条简短易行的路线将会非常顺利。 首先，我建议您备份当前的wpa_supplicant.conf文件：
sudo mv /etc/wpa_supplicant/wpa_supplicant.conf /etc/wpa_supplicant/wpa_supplicant.bak
接下来，我建议你编辑/ etc / network / interfaces：
auto lo iface lo inet loopback auto wlan0 iface wlan0 inet static address 192.168.1.150 netmask 255.255.255.0 gateway 192.168.1.1 wpa-essid MYESSID12345 wpa-psk MYPASSWORD$1234567
当然，请在此处替换您的详细信息。 重启界面：
sudo ifdown wlan0 && sudo ifup -v wlan0
测试：
ping -c3 www.ubuntu.com
如果您获得ping结果，则表示您已连接。
