CentOS 7: Can't connect wifi using wpa_supplicant

Question

I recently got a new wireless card, specifically Intel Dual Band Wireless-AC 7260 WiFi Bluetooth Half Mini Card. Previously I had been connecting with ethernet so this machine has never been on the wifi.

I've attempted to use nmcli to get things working to no avail, so I've fallen back to trying to get everything setup using wpa_supplicant.

First things first, I ensure that my interface is up with ifconfig wlp3s0 up. Next I attempt to scan for my wireless access point with iwlist wlp3s0 scanning which returns:

I've setup my wpa_supplicant.conf file as such:

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

I try to run wpa_supplicant with wpa_supplicant -B -Dnl80211 -iwlp3s0 -c/etc/wpa_supplicant/wpa_supplicant.conf which simply returns Successfully initialized wpa_supplicant.

Output from dmesg returns:

Any ideas why I can't connect?

Answer 1

After initializing with wpa supplicant, you'll need to use the DHCP client to request an IP addr like

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

Answer 2

Using Centos7 myself, I could connect to wifi using

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

then

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

What error/issue do you get using nmcli to connect your SSID?
