How do I start wireless network and enter the wireless network password in linaro? When I ran android and went to start the wireless it asked for a password and worked just fine.
what platform are you using (hikey/dragon) and what OS (ubuntu/android)?
platform dragon 410c, os ubuntu
if you upgraded to 15.07  you should be able to click on the icon at the right side of the toolbar (next to the sound icon).
Note that the same method would work with 15.06 release too.
