Ubuntu: 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.

$ 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)        Subsystem: Lenovo Device [17aa:3821]        Kernel driver in use: r8169    03:00.0 Network controller [0280]: Qualcomm Atheros Device [168c:0041] (rev 20)  Subsystem: Lenovo Device [17aa:3545]    04:00.0 Display controller [0380]: Advanced Micro Devices, Inc. [AMD/ATI] Sun [Radeon HD 8500M] [1002:666f] (rev ff)    $ rfkill list  0: ideapad_wlan: Wireless LAN      Soft blocked: no      Hard blocked: no  1: ideapad_bluetooth: Bluetooth      Soft blocked: no      Hard blocked: no  2: hci0: Bluetooth      Soft blocked: no      Hard blocked: no    $ uname -r  3.13.0-32-generic  

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.
