4. Edit the wpa_supplicant.conf file

   1. Open the "wpa_supplicant.conf" file with the following command:

      vi /etc/wpa_supplicant.conf

   2. Near the bottom of the file, comment out the following line:

      #concurrent_sched_scan=1

      
      

   3. At the bottom of the file, add in a network node so it looks similar to the following (using your WiFi network information):

      network={
              ssid="your network name in quotes"
              psk="your password in quotes"
              proto=WPA2
              key_mgmt=WPA-PSK
      }

   4. Save and exit the wpa_supplicant file
      

   
   

5. Execute the following command to start wpa_supplicant and connect to your WiFi network

   wpa_supplicant -B -Dnl80211,wext -i wlan0 -c /etc/wpa_supplicant.conf

6. When the module connects to WiFi you should see the following terminal output:

   [ 1271.610097] wlan0: send auth to ac:9e:17:af:73:28 (try 1/3)[ 1271.639322] wlan0: authenticated
   [ 1271.650623] wlan0: associate with ac:9e:17:af:73:28 (try 1/3)
   [ 1271.660521] wlan0: RX AssocResp from ac:9e:17:af:73:28 (capab=0x411 status=0 aid=5)
   [ 1271.677192] IPv6: ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready
   [ 1271.683609] wlan0: associated
   [ 1271.755467] wlcore: Association completed.

   
   

7. Now that you are connected to your WiFi network, ping your favorite local device with the following command to verify it is working properly 

   ping -I wlan0 -c 5 <IP addr>
