I am new to ubuntu and I just upgraded to 16.04 and the option to connect to a wifi network has disappeared. The following pictures explain it better

enter image description here

However when I click "Edit Connections..." I do see my wifi network here

enter image description here

from the tutorial here it says to check Software & updates >> Additional Drivers and it should show a Broadcom wireless driver that is not enabled, however when I navigate there I do not see any wireless drivers. All I see is the following.

enter image description here

Also when I do lspci -vnn | grep Network I get 3e:00.0 Network controller [0280]: Intel Corporation Wireless 8260 [8086:24f3] (rev 3a) So I'm not even sure I should be looking for a Broadcom driver.

If someone could give me some advice as to how to fix this it would be greatly appreciated

Your wireless might not appear in Network Manager for several reasons. First, is the wireless turned off by the airplane mode button or wireless switch? Check, from the terminal:

rfkill list all

Is the wireless hard blocked? If so, find and press the button or switch.

The wireless might not appear in Network Manager because it is managed elsewhere; typically in the file /etc/network/interfaces. Check:

cat /etc/network/interfaces

Is your wireless interface, perhaps wlan0, listed? If you’d rather that Network Manager handle the wireless, amend the file to remove wlan0 or whatever the wireless interface is:

sudo nano /etc/network/interfaces

Change the file to read:

# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback

Save the changes to the file (Ctrl+o) and exit nano (Ctrl+x).

Restart NM:

sudo service network-manager restart

Any improvement?
