MSI Wind U160 laptop with RA LINK wireless network built-in
Dual boot, Win7 starter , Ubuntu 12.04 LTS

Wireless works in Windows, but doesn't in Ubuntu.

In Ubuntu menu says "Wireless networks device not ready"

I'm not a Linux user; have read lot about similar issues with RT3090 and tried most of solutions.
Wireless still not working.

Any help is greatly appreciated.
Thank you.

*******
I use for test a wireless router with encryption disabled.

****************
Soft and hard block seems to work OK.
rfkill output is consistent with the state of hardware switch or software setting in menu.
