After booting up my laptop my wifi suddenly stopped working. At first the lshw could not detect my wifi at all. But then I followed some steps here. I updated all the software after that using the apt-get command. My laptop has Intel® Dual Band Wireless-AC 3160 Plus Bluetooth*. I installed the 

linux-firmware and linux-firmware-nonfree.

The wifi appeared for a while but then disappeared again. I also installed 

linux-image-generic-lts-quantal.

As a result I am unable to run the wifi on windows( dual boot).

here are some command snapshots:

Could someone help me with the solution as the wifi is not working accross windows as well( dual boot). I hope i have provided all the information there should be. I am also unable to find the reason for the reason for the problem. After booting up the wifi was suddenly not working.

You installed an obsolete kernel.

Both linux-firmware-nonfree and linux-image-generic-lts-quantal are obsolete.

Run

sudo apt-get install linux-generic-lts-xenial

and reboot.

  • this is not working. The wifi is now not showing even while running the lshw command or rfkill – matrixaliser Sep 06 '16 at 13:39
  • Were you connected to internet? Did the kernel install? What does uname -a show. Please add output of dmesg | grep iwl to your question. – Pilot6 Sep 06 '16 at 13:41
  • I am connected to the internet using the ethernet but now there is also a option of Auto Ethernet which I am not sure what it is for. Also the rfkill shows a new message now. – matrixaliser Sep 06 '16 at 14:25
  • hey the problem has again crept up after i left the system suspended. I think something is still messing up the system drivers. It is not working on both windows and linux now. – matrixaliser Sep 06 '16 at 17:09
  • Hey @Pilot6 the problem has again crept up after I suspended my laptop for a while. I guess i have not been able to reach a permanent solution. – matrixaliser Sep 06 '16 at 17:17
  • the bluetooth has also disappeared now and there is no trace of the wireless card except the rfkill which show s the dell-rbtn0 – matrixaliser Sep 06 '16 at 17:34
  • This is something specific to the laptop UEFI firmware. I suggest to file a bug report. – Pilot6 Sep 06 '16 at 18:06
