CentOS 7：无法使用 wpa_supplicant 连接 wifi

我最近买了一张新的无线卡，特别是英特尔双频无线-AC 7260 WiFi 蓝牙半迷你卡。之前我一直用以太网连接，所以这台机器从来没有连接过wifi。

我尝试使用nmcli来让事情正常工作，但没有成功，所以我又转而尝试使用wpa_supplicant.

首先，我确保我的界面与ifconfig wlp3s0 up.接下来，我尝试扫描我的无线接入点，iwlist wlp3s0 scanning返回结果：

我已经wpa_supplicant.conf这样设置我的文件：

ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=wheel

# reading passphrase from stdin
network={
    ssid="Foobar"
    #psk="my-pass-phrase"
    psk=af865233abdc002e9181256fdbc34b81fa956fcf28ac33fd0ec92e25241eb6f3
    key_mgmt=WPA-PSK
        proto=WPA RSN
        pairwise=CCMP
    group=CCMP

我尝试运行 wpa_supplicant ，wpa_supplicant -B -Dnl80211 -iwlp3s0 -c/etc/wpa_supplicant/wpa_supplicant.conf它只是返回Successfully initialized wpa_supplicant。

dmesg 的输出返回：

有什么想法为什么我无法连接吗？

答案1

使用 wpa 请求者初始化后，您需要使用 DHCP 客户端来请求 IP 地址，例如

dhclient wlp0... //replace with your interface name

答案2

我自己使用Centos7，我可以使用以下命令连接到wifi

 $ nmcli dev wifi list
 *  SSID                      MODE   CHAN  DÉBIT    SIGNAL  BARS  SÉCURITÉ    
    Livebox-3WYX              Infra  1     54 Mo/s  65      ▂▄▆_  WPA2  
 ...

然后

 $ nmcli --ask dev wifi connect Livebox-3WYX
 Mot de passe : ...
 Périphérique « wlo1 » activé avec « 9c234370-5a39-468d-9b62-202cbc56e9fe ».

使用 nmcli 连接 SSID 时遇到什么错误/问题？
