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
02:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller [10ec:8168] (rev10)

$ rfkill list

$ 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.
