![尝试 #1wpa_supplicant.conf](https://linux22.com/image/874577/%E5%B0%9D%E8%AF%95%20%231wpa_supplicant.conf.png)
我的桌面系统上安装了 Ubuntu Server 12.04(文本模式,没有 X-Window),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。
一开始尝试用iwconfig
它连接,却发现无法连接到 WPA2 安全网络!一开始iwconfig
显示:
lo no wireless extensions.
eth0 no wireless extensions.

并sudo iwlist wlan0 scanning
显示:

运行后显示sudo ifconfig wlan0 up
:sudo iwlist wlan0 scanning

我安装了该软件包wpasupplicant
以连接到使用 WPA2 保护的无线网络。但使用此软件包时存在一些问题:
我尝试按照说明进行操作这个答案
wpa_passphrase 'MYESSID12345' 'MYPASSWORD$1234567' > CONFIG_FILE
执行上述命令后,我编辑了 CONFIG_FILE ( /etc/wpa_supplicant/wpa_supplicant.conf
),使其包含:
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
。结果出现以下错误stderr
:

执行完最后一条命令后,wlan0
程序就挂了,我必须再次使用命令来修复sudo iwconfig wlan0 up
。我还尝试删除network-manager
软件包,因为有评论说这也许能解决问题,但没有成功。
还尝试按如下方式编辑wpa_supplicant.conf1
文件:
尝试 #1wpa_supplicant.conf
network={
ssid="MYESSID12345"
#psk="MYPASSWORD$1234567"
psk=1234567890abcdef1234567890abcdef1234567890abcedf1234567890abcdef
}
尝试 #2wpa_supplicant.conf
network={
ssid="MYESSID12345"
scan_ssid=1
key_mgmt=WPA-PSK
#psk="MYPASSWORD$1234567"
proto=RSN WPA
pairwise=CCMP TKIP
group=CCMP TKIP
psk=1234567890abcdef1234567890abcdef1234567890abcedf1234567890abcdef
}
答案1
首先,我认为如果您的路由器设置为使用 WPA2-AES 而不是 TKIP,您会更幸运。
其次,我认为你选择了一条漫长而复杂的路线,而短而简单的路线却能完美地发挥作用。首先,我建议你备份当前的 wpa_supplicant.conf 文件:
sudo mv /etc/wpa_supplicant/wpa_supplicant.conf /etc/wpa_supplicant/wpa_supplicant.bak
接下来,我建议您编辑 /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,在这里替换你的详细信息。重新启动界面:
sudo ifdown wlan0 && sudo ifup -v wlan0
测试:
ping -c3 www.ubuntu.com
如果您收到 ping 结果,则表示您已连接。
答案2
我今天也遇到了这个问题。我取出一个wpa_supplicant.conf
过去在我的 Raspberry Pi 设备上对我有用的文件并在这里使用它。一旦我尝试使用这个文件,我的设备wpa_supplicant
就会持续连接。
今天我花了一些时间尝试禁用一些部分,network=
以尝试缩小哪个部分适用于我的无线网络,但过了一段时间我放弃了。删除并放回个别部分似乎可以缩小范围,但我不知道为什么它仍然无法连接,所以我放弃了,把整个东西放回去,并从我的路由器上获得了一个 DHCP IP 地址。
这是/etc/wpa_supplicant/wpa_supplicant.conf
我使用的文件:
network={
ssid="MYESSID12345"
scan_ssid=1
psk="MYPASSWORD$1234567"
proto=RSN
key_mgmt=WPA-PSK
pairwise=CCMP
auth_alg=OPEN
priority=999
}
network={
ssid="MYESSID12345"
psk="MYPASSWORD$1234567"
proto=RSN
key_mgmt=WPA-PSK
pairwise=CCMP
auth_alg=OPEN
priority=99
}
network={
ssid="MYESSID12345"
scan_ssid=1
key_mgmt=NONE
priority=2
}
network={
ssid="MYESSID12345"
psk="MYPASSWORD$1234567"
proto=RSN
key_mgmt=WPA-PSK
pairwise=CCMP
auth_alg=OPEN
priority=-1
}
有了这个,我运行了:
$ sudo -i
# cd /etc/wpa_supplicant
# wpa_supplicant -Dwext -i wlp1s0 -c wpa_supplicant.conf
Successfully initialized wpa_supplicant
ioctl[SIOCSIWENCODEEXT]: Invalid argument
ioctl[SIOCSIWENCODEEXT]: Invalid argument
...
wlp1s0: CTRL-EVENT-CONNECTED - Connection to ... completed [id=0 id_str=]
我仍然在标准输出中收到相同的错误,但情况看起来仍然/var/log/syslog
比以前更好,并且信息量也更多。
之后在单独的控制台中:
# dhclient -v -r wlp1s0
# dhclient -v wlp1s0
我得到了我的 IP 地址,因此我能够继续:
$ ping 8.8.8.8
