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

Question

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.

$ lspci -nnk | grep -iA2 net

$ uname -r

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

How about creating a Ubuntu 14.04 bootable USB-stick and see if it supports your ethernet/wireless out-of-the-box? Have you tried that? Or is there a specific reason you need to run 12.04? — MadMike, Jun 26 '15 at 06:44
Thanks for your reply Mr. MadMike I am using one erp product which is compatible with ubuntu12.04 so i prefer it. But as per your suggestion I have check with install Ubuntu 14.04 and with bootable USB using try ubuntu option. I have check with searching additional driver option. But no success same issue no any connection. Is there any other way or suggestion? — Heer, Jun 27 '15 at 06:51
This is a very new Qualcomm wireless. There is a new kernel module for it ath10k. But there is a problem with firmware, that should be extracted from Windows drivers. But I see no problems with Ethernet. — Pilot6, Jun 27 '15 at 13:10
The driver is installed. Post route -n and ping -c 1 google.com. — Pilot6, Jun 27 '15 at 14:00

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.
