Wireless, Ethernet and Bluethooth not working with lenovo G5080 under Ubuntu 12.04.5/14.04 64bit

I have Lenovo G50-80 laptop and installed Ubuntu 12.04.05 or 14.04 for 64 bit.
But I can't establish a wireless connection or a ethernet connection.

Which driver do I have to install to connect with wireless and ethernet and from where?

Hello all I got solution from this ubuntu bug link https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1436940/+index?comments=all
It has not official solution from ubuntu, bug is still pending but I have followed comment #81 & #90 from it's comments and my wifi and wired both are working now. One more point need to share that. After apply solution I got update from ubuntu and I updated my ubuntu but unfortunately I lost my both wifi & wired connection. Again I apply #81 & #90 comment from above bug comments it is working fine now. So after apply fixes take care of new updates for ubuntu.
I have check above with 14.04 64 bit. not checked with ubuntu 12.04. May be above fixes works with ubuntu 12.04 too.
