wifi power constantly cycling

CReil · ‎07-12-2017

Hello! I'm running http://www.jubilinux.org/ jubilinux on an http://www.mouser.com/search/ProductDetail.aspx?r=607-EDI2%2eLPON%2eAL%2eS Edison EDI2.LPON.AL.S. I'm having lots of trouble connecting through wifi. I've tried several different networks, and am familiar with the standard procedure of connecting outlined in the https://www.intel.com/content/www/us/en/support/boards-and-kits/000006202.html Edison support docs.

I am able to connect intermittently through wifi, but the connection fails frequently. I'm also unable to sync using ntpd over wifi (I've tried on multiple networks).

I'm seeing this output when connected to the board over serial.

Any suggestions for getting the wifi working smoothly are much appreciated!

Hi rainbow_lazer,

Thank you for contacting us.

I've been investigating about the Jubilinux image. Please keep in mind that the only image that we support is the Yocto image, so the suggestions we offer for Jubilinux will be limited. Nevertheless, we'll try to help you troubleshoot this issue.

We compared the output of the wpa_supplicant.conf files. The output is slightly different:

ctrl_interface=/var/run/wpa_supplicant

ctrl_interface_group=0

config_methods=virtual_push_button virtual_display push_button keypad

update_config=1

fast_reauth=1

device_name=Edison

manufacturer=Intel

model_name=Edison

network={

ssid="Intel2.4"

key_mgmt=WPA-PSK

pairwise=CCMP TKIP

group=CCMP TKIP WEP104 WEP40

eap=TTLS PEAP TLS

psk="xxx"

}

network={

ssid="Intel5.0"

key_mgmt=WPA-PSK

pairwise=CCMP TKIP

group=CCMP TKIP WEP104 WEP40

eap=TTLS PEAP TLS

psk="xxx"

}

We also looked for the /etc/network/interfaces file, but this file doesn't exist in the Yocto image.

Fortunately, we found a guide that shows how to configure Wi-Fi in Jubilinux. The guide is the following: http://openaps.readthedocs.io/en/latest/docs/walkthrough/phase-0/setup-edison.html . Please make sure to check for all the prerequisites and follow the steps to configure Wi-Fi.

If you're interested in using the Yocto image, you should go here: https://software.intel.com/en-us/get-started-edison-windows-step2 and follow the installation process. If you use this image it'll be a lot easier for us to continue to assist you.

Let us know your results after following the guide.

Regards,

-Sergio A

Hi rainbow_lazer,

Do you still need assistance with this case?
