Enable Wifi on Raspbian Using WPA Supplicant

~ Carlo Gonzales

Step 1

Edit your wpa_supplication config file.

sudo nano /etc/wpa_supplicant/wpa_supplicant.conf

Step 2

Then copy and paste the configurations below and edit the SSID and WIFI PASSWORD.

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=PH

network={
    ssid="[SSID]"
    psk="[WIFI PASSWORD]"
    scan_ssid=1
    proto=RSN
    key_mgmt=WPA-PSK
    pairwise=CCMP
    auth_alg=OPEN
}

Note: Double check your own Wifi settings and change the network configuration as you see fit. See WPA Supplicant Config Documentation for details. Also use iwlist [NET INTERFACE] scan to get more infor on your Wifi settings

Note on Hidden SSID: If you’re using hidden SSID for your Wifi hotspot, make sure to use scan_ssid=1 This uses probe request specific to your hidden SSID, and has a high latency.

Step 3

After setting the WPA Supplicant configurations. Restart your network manager with:

sudo service networking restart

Note: If restarting your network manager doesn’t connect you to wifi. Restart your board.
