I have successfully installed Ubuntu 16.04 LTS. However, when I boot into the system, I cannot find any wireless connections

enter image description here

I tried rfkill list and it displays:

0: hci0: Bluetooth
    Soft blocked: no
    Hard blocked: no

sudo lshw -C network displays:

Here's what I have tried: I have run sudo apt-get update and in my 'Software and Updates' -> Additional Drivers, i have selected the Broadcom drivers. I booted the system and none of this seems to work. What can I do?

  • Your sudo lshw -C network displays *-network UNCLAIMED. Please refer the post Intel wireless 8260 - unclaimed network so that you get an idea to resolve your issue! – Marmayogi Apr 04 '19 at 13:02
  • It will not fix his Broadcom device to intall an Intel driver! @Marmayogi – chili555 Apr 04 '19 at 13:47
  • Please edit your question to show the exact response to the terminal command: sudo modprobe wl && dmesg | grep wl A little bird told me it is secure boot! Welcome to Ask Ubuntu. – chili555 Apr 04 '19 at 13:48
  • That is not my point @chili555. I suggested to the questioner to get an idea about network UNCLAIMED and how it is is solved in the case of Intel driver. I hope you see my point. – Marmayogi Apr 04 '19 at 15:18
  • Please edit the question and post the output of the following commands: 1. ls /sys/firmware/efi/ and 2. mokutil --sb-state – Marmayogi Apr 04 '19 at 15:44
