![Intel WiFi Card Not Recognised in Ubuntu 16.04 [duplicate]](https://ago.mlga.ek.gov.ng/uploads/intel-wifi-card-not-recognised-in-ubuntu-16-04-duplicate_720.jpg)
My Wifi card is not being recognised. I think it may be because the hardware is relatively new (it's a new Dell Precision Laptop). Have been trying to figure out how to backport new drivers but that seems enabled already so perhaps I have to move to a newer kernel. I have pasted below the output from the wifi script. Any suggestions much appreciated!

In the kernel version included in Ubuntu 16.04, your exact device 8086:24fd and subsystem 0050 are not yet covered. It is covered in Ubuntu 17.04; from my machine:
$ modinfo iwlwifi | grep 0050 alias: pci:v00008086d000024FDsv*sd00000050bc*sc*i* You could certainly reinstall and use 17.04 instead of 16.04. You could also download and install the 4.10-xx kernel and required firmware. If you'd prefer to do the latter, then I assume that your installation is 64-bit; confirm:
arch If the terminal returns x86_64 then yours is a 64-bit install. Download the files to your desktop:
Install them all from the terminal:
cd ~/Desktop sudo dpkg -i *.deb Reboot and tell us if your wireless is working.
7Installing a kernel outside of repository is not a good idea because you will miss security updates. You should install the Ubuntu HWE instead.
sudo apt-get install --install-recommends linux-generic-hwe-16.04 xserver-xorg-hwe-16.04 This will upgrade your kernel and xorg stack. At this time, it would upgrade you to the kernel of Ubuntu 17.10 (kernel 4.13).
