Wifi is not turning on?

[Jim Morse]

Hi All,

 

I was finally able to create image and boot chromium from USB and trying to use it on the fly without installation. However I found that WIFI was always turned off and when I tried to turn it ON it turns it off by itself. When I connected my LAN cable then WIFI came online by itself and then I was able to see all WIFI connections and connect to it seamlessly.

There was no other problem with the OS, it works great and I love it. :)

I tried it on DELL laptops and Lenovo laptop.Both had exactly the same behavior. Is there any solution for this problem? am i missing some drivers or is it due to power save mode? how can i check?

Thanks, Jim

Hi Jim,

You just need to rebuild with -wifi_bootstrapping use flag in your make.conf, and the problem will go away.

hmm, interesting.  filed https://crbug.com/778731 to clean up.

That's great, thanks. I thought it's a feature not a bug :D

Thanks guys,

I tried doing this , however I got following error, I am not sure if i am doing it correctly. Could you please suggest me, if I have to make that change in make.conf???

Sorry I am new to chromium os.

I think you want:

  USE="-wifi_bootstrapping" ./build_image --board=$BOARD

But it also looks from the bug like this was turned off by default by https://crrev.com/c/740042 on Oct 30.
