Enable Wireless in Mint 19

[zerubbabel]

I just installed Mint 19 on my Dell Latitude E6540, and while I was booted from the installation flash drive the wireless worked perfectly, but after booting the freshly installed system, and even after applying all the post-installation updates, the wireless is not enabled. How can that be, since it worked fine from the installation boot media? How can I enable it?

Evidently the correct driver was not installed.
Please go to a terminal and type this command and post the output here.

Code: Select all

inxi -Nn

Also the output of this command.

Code: Select all

rfkill list

You will need to be connected via Ethernet cable then in a terminal type these commands,one at a time. Disconnect Ethernet and reboot see if it works.

Code: Select all

sudo apt-get install linux-headers-generic
sudo apt-get install --reinstall bcmwl-kernel-source

if you do not want to use the terminal you can try the driver manager found under Administration in the Menu. your looking for the WL driver.
Good Luck.
