Wireless BCM43142 not detected on ubuntu 16.04

I have a Dell Inspiron 14Z - 5423. I installed Ubuntu and the wireless was working fine. Some days ago it stop working. Can someone help me?

I tried upgrading the system and I tried installing the firmware-b43-installer package and it didn't work.
Also tried the bcmwl-kernel-source_6.30.223.248+bdcom-0ubuntu0.2_amd64.deb package from the ubuntu website and it didn't work.

In the network devices doesn't appear the wifi option.

This is the output of the command in the Wireless Troubleshooting Procedure:
