Hi ,
I have a beabglebone installed with Eclipse Kura (with UI and Networking). I tried configuring Wifi using Kura UI. I was not able to connect to wifi. Could you please guide me in fixing this issue. Also if you could provide some reference material for configuring wifi will be very helpful.

Please find below step i performed and logs for the same.


1. downloaded debian image (https://debian.beagleboard.org/images/bone­debian­7.9­lxde­4gb­armhf­2015­11­12­4gb.img.xz) and flashed it to sd card on BBB.
2. Installed oracle java 7
3. nstalled kura with UI and Networking (https://s3.amazonaws.com/kura_downloads/debian/release/1.4.0/kura_1.4.0_beaglebone_debian_installer.deb)
4. rebooted the kura after installation
5. disabled webservices as mentiond in https://eclipse.github.io/kura/doc/beaglebone-quick-start.html
6. In web ui selected network -> wlan0
7 in wireless selected station
Wireless Mode: Station
Network Name : <wifi id >
Wireless Security : wpa2
Wireless password : <wifi password>

You may have another wpa_supplicant process already running or the file was
left by an unclean termination of wpa_supplicant in which case you will need
to manually remove this file before starting wpa_supplicant again.

Hi Praful,

I think the problem is that you do not have a group 'weel' defined in the /etc/group file. Please try adding this line to the /etc/group:
wheel:x:10:root

Best regards,

Ilya
