Ubuntu – Can’t get wifi to work on Ubuntu 16.04 with Intel wireless 7260 (rev c3)

I am new to using Ubuntu. I dual booted my HP laptop with Windows 10 and Ubuntu 16.04. I am unable to see any wireless networks on Ubuntu, but it works perfectly if I use a wired connection. My network controller is an Intel 7260 (rev 3). When I check "Software & Updates" my wireless driver does not show up. Any suggestions as to how I should proceed?

Running

lspci -nnk | grep 0280 -A2

produces the output:

09:00.0 Network controller [0280]: Intel Corporation Wireless 7260 [8086:08b1] (rev c3)
DeviceName: Intel Stone Peak 2 7260 ac 2x2 + BT4 LE Combo
Subsystem: Intel Corporation Dual Band Wireless-AC 7260 [8086:c070]

Running

rfkill list all

produces the output:

Running
