I recently installed ubuntu 14.04 LTS on my new flex 3 1480. I do not see wireless option. I tried the solution mentioned in this post but it doesn't work. Output of the wireless script can be found here . Any help is appreciated. Thanks

  • Reinstall the backports – Jeremy31 Jan 13 '16 at 10:09
  • Sorry for the naive question but by reinstall do you mean downloading the backports and installing them again? Is there any 'uninstall' step involved? I did that again as mentioned in your answer here (http://askubuntu.com/questions/708061/qualcomm-atheros-device-168c0042-rev-30-wi-fi-driver-installation?lq=1) but it still doesn't work. – shivani_s Jan 16 '16 at 16:43

  • backath10k, 2.0, 3.13.0-74-generic, x86_64: installed backath10k, 2.0, 3.19.0-25-generic, x86_64: installed backath10k, 2.0, 3.19.0-43-generic, x86_64: installed – shivani_s Jan 17 '16 at 15:51
  • dpkg -r backath10k/2.0 --all Reboot and then try the answer in the duplicate post but use the instructions I added for after a kernel update, 5 lines of code – Jeremy31 Jan 17 '16 at 16:12
