I have a Dell laptop running Ubuntu 14.04 LTS
I purchased it new about a month ago.
This morning I got a popup about a Software Update available, so I updated, and now the wifi is not working at all.
I checked the networking menu and it shows NO networks detected.
Everything worked just fine until this latest software update.
Here's the output from lspci -knn | grep Net -A2
3a:00.0 Network Contoller : Intel Corporation Wireless 8260 [8086:24f3] (rev 3a)
Subsystem: Intel Corporation Device [8086:0050]
3b:00.0 Unassingned class [ff00]: Realtek Semiconductor Co. ltd. Device [10ec:525a] (rev 01)
I tried the mokutil disable validation as described in the other problem report
sudo apt install mokutil
sudo mokutil –disable-validation
it forced me to create a new password, but still no wifi!!!
Here is lspci -vvnn

What driver should I have for the Intel 8260? I did lmod and I didn't see anything that looked like a wifi driver…
