BPI-P2 Zero - WiFi issue

Hi, I have some trouble with the new BPI-P2 Zero and its wifi. I have loaded your Ubuntu image (Ubuntu 16.04) to a SD card and booted the P2 zero. Booting works fine but I can not connect to any wifi network. The available wifi networks are found but after typing in the WPA password the attempt fails.

Do you have any suggestions?

Best regards, Andreas

Hello, May I know how did you config the wpa_supplicant.conf?

I did a test on my board, it should support.

Hi Jackzeng,

network={ ssid=“AP-Name” psk=“12345678” }

Error massage: error

Please help me. Thanks a lot.

Your setting could be like this:

network={
ssid="AP-Name"
psk="12345678"
}

Hi ZB,

I have already confirmed, but the same failed.

nano /etc/wpa_supplicant/wpa_supplicant.conf 01

wpa_supplicant -iwlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf 02

try “kill wpa_supplicant” and do “wpa_supplicant -iwlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf” again.

Hi ZB,

I follow your suggest. execution succeed.

Step 1、nano /etc/wpa_supplicant/wpa_supplicant.conf`
network={
ssid="AP-Name"
psk="12345678"
}

Step 2、Check wpa_supplicant ID:
            ps -ef|grep "wpa_supplicant"

Step 3、kill -9 wpa_supplicant ID

Step 4、Run "wpa_supplicant -iwlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf"

Step 5、Run "dhclient wlan0"

Success.  

Thanks a lot.

Same issue. Nothing worked. the very line: " wpa_supplicant -iwlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf " hangs.

It gives output:

successfully initialized wpa_supplicant
wlan0: Trying to associate with SSID 'WIFI_NAME'
wlan0: associated with xx:xx:xx:xx:xx:xx
wlan0: CTRL-EVENT-SUBNET-STATUS-UPDATE status=0

wlan0: CTRL-EVENT-CONNECTED - Connection to xx:xx:xx:xx:xx:xx completed [id=0 id_str=]

That’s where it hangs. I do CTRL + C after a while, and it says:
