I installed Ubuntu 16.04 LTS on my Alienware 17 R3, which comes with Killer Wireless-AC 1535 WiFi card. The WiFi hardware seems to be detected but no WiFi hotspots are being detected.

I learnt somewhere that updating to the latest kernel would fix the problem. The kernel verison according to uname -r is 4.4.0-22-generic. Is a more recent version of kernel required?

Any help regarding this would greately help me since I will have to start my development asap and Linux is the go-to platform where I work.

Thanks

Edit: Output of lspci -knn | grep Net -A2

    Please [edit] your question and add output of lspci -knn | grep Net -A2 terminal command. – Pilot6 Jun 11 '16 at 18:07
  • Hi, I have added the requested output. Please guide me further – Sagar B Hathwar Jun 11 '16 at 18:38
  • This is a firmware issue. You can search for an answer regarding [168c:003e]. For 16.04 you do not need any drivers, they are already in kernel, but you may need firmware. – Pilot6 Jun 11 '16 at 18:39

  • @Pilot6 Is this the firmware you are talking about? The board.bin file? – Sagar B Hathwar Jun 11 '16 at 18:43
  • I am not quite sure. You'd better copy them all. – Pilot6 Jun 11 '16 at 18:47

    That page is over 6 months old, better off using linux-firmware from the duplicate post. Kalle has made changes and added a board-2.bin since then – Jeremy31 Jun 11 '16 at 18:48
  • This worked!. Thanks! Updating the Linux firmware to 1.158 worked. Sweet. My development work would have gone for a toss without this! I have been trying to make this work from days, and nope, nothing worked. One more question though. I keep getting "Booting in insecure mode" when I boot up Ubuntu, though I have enabled secure boot in BIOS. Any fix for this? – Sagar B Hathwar Jun 12 '16 at 04:21
