Wireless is not working in my system?

  • 772

I have a HP pavilion 15-e057ej Laptop.

In ubuntu 12.04.04 64-bit the wireless network worked fine.

After I install fresh 14.04 64-bit, wireless isn't working - it's not enable.

What can I do?

Here's some more information:

At both versions of ubuntu: 12.04.04, 14.04 the light of the WiFi button is orange, mean it close. at 12.04.04 the wireless working fine and enable.
At 14.04 it not working and the WiFi is not enable.
At both version of ubuntu 12.04.04 and 14.04 the button to switch the WiFi on - turn the light to blue, is not doing anything.

use script from this question:

  1. Your rfkill list command is shows hard blocked: yes.

    That means that your wireless card is disabled. It could be that there is a switch at your laptop to enable/disable wireless. Mine has it. With rfkill you can just unlock a software block not a hardware switch.

    It could also be that in BIOS your wireless card is disabled. Boot your machine in BIOS and check if something is disabled there.

    I install again Ubuntu 12.04.03, the driver of the wireless card is working there. I force the Ubuntu to upgrade to 14.04. that way the driver was stay on my system. with this command found at this link sudo update-manager -d

    After a while, the Ubuntu upgrade with my wireless driver.
