I've been trying for two days, have not been able to get my WiFi to work on Raspberry Pi 3

I've tried the Jessie Lite build from FR24, and even the full download from Raspberry site.

completely confused, please help. Thanks, Brian.

Hi Joe,, the Flight Radar 24 dist is built on Raspbian Jessie light here is the lsmod

Looks like your WiFi adapter's driver didn't load. This is frequently due to missing firmware. You may want to check your /lib/firmware/brcm folder: if it's missing or empty, try putting these files there and reboot. You might also try to load the driver manually:

sudo modprobe brcmfmac

If that won't help, check dmesg output for clues (e.g. use grep to search for keywords like "wlan", "mac", "firmware", "error"). Those messages are often clear enough to figure out what's wrong.


Follow https://www.raspberrypi.org/documentation/configuration/wireless/ or just these pictures.

Click on this button in the upper right corner.

Select your network.

Enter the correct passphrase.

After some seconds you're done. On the next boot you will be connected automatically.

Also check what changes were made to /etc/wpa_supplicant/wpa_supplicant.conf.

Without a GUI, it works like this:

Edit /etc/network/interfaces to make the wlan0 entry look like this:

allow-hotplug wlan0
iface wlan0 inet manual
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

Shutdown wlan0 and scan for APs:

sudo ifdown wlan0
sudo iwlist scan
      Cell 02 - Address: F0:D1:A9:FF:FF:FF
                Frequency:2.462 GHz (Channel 11)
                Quality=44/70  Signal level=-66 dBm  
                Encryption key:on
                ESSID:"MOB 4"

Add the AP to /etc/wpa_supplicant/wpa_supplicant.conf:

    ssid="MOB 4"
    psk="not my real psk"

Start wpa_supplicant:

sudo /sbin/wpa_supplicant -s -B -P /run/wpa_supplicant.wlan0.pid -i wlan0 -D nl80211,wext -c /etc/wpa_supplicant/wpa_supplicant.conf
  • hello ott, this version of raspbian (jessie lite) doesn't have a gui – Brian Tucker Jul 10 '16 at 15:05
  • @BrianTucker I've edited my answer to include a non-GUI solution. – ott-- Jul 10 '16 at 16:07
  • thanks ott, checked the changes got the following pi@raspberrypi:~ $ sudo ifdown lan0 ifdown: interface lan0 not configured pi@raspberrypi:~ $ sudo iwlist scan lo Interface doesn't support scanning. I'm beginning to wonder if I don't have a bad Pi3, this is from Vilros - anyone know of any diagnostics I could run? – Brian Tucker Jul 10 '16 at 16:17
  • @BrianTucker What do you get from ifconfig wlan0 and iwconfig wlan0 (maybe needs sudo)? – ott-- Jul 10 '16 at 16:24
  • pi@raspberrypi:/sbin $ sudo ifconfig wlan0 wlan0: error fetching interface information: Device not found pi@raspberrypi:/sbin $ sudo iwconfig wlan0 wlan0 No such device – Brian Tucker Jul 10 '16 at 16:52
