How to configure wpa_supplicant.conf to get wifi work?

[Mian Tang]

Hi,

I'm using BeagleBone Black with Wifi dongle plugged-in (TL-WN722N), and trying to configure BeagleBone black to get wifi work with my office's wifi network. In general, username and password are necessary for my phone, but it's more  complicated to configure BeagleBone black. I did following:

(1) configure /etc/network/interfaces:

    auto wlan0

    allow-hotplug wlan0

    iface wlan0 inet dhcp

        wpa-driver wext

        wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

(2) configure /etc/wpa_supplicant/wpa_supplicant.conf:

    ctrl_interface=/var/run/wpa_supplicant

    ap_scan=1

    network={

       ssid="officewave"

       proto=WPA2

       pairwise=CCMP

       group=CCMP

       key_mgmt=WPA-EAP

       eap=PEAP

       identity="myemailaddress"

       password="12345678"

    }

And after that, I reboot and run the following command:

    wpa_supplicant -B -Dwext -iwlan0 -c/etc/wpa_supplicant/wpa_supplicant.conf -f /var/log/wpa_supplicant.log

And got the error below:

    wlan0: failed to initiate ap scan

I'm a beginner. Could anyone please tell me how to do with this issue, or any suggestions?

Thanks a lot.

If your using Jessie, just use connmanctl:

##connman: WiFi
#
#sudo connmanctl
#connmanctl> tether wifi disable
#connmanctl> enable wifi
#connmanctl> scan wifi
#connmanctl> services
#connmanctl> agent on
#connmanctl> connect wifi_*_managed_psk
#connmanctl> quit
