Title: Dell D620 Wi-Fi off
Post by: psikeyhackr on September 22, 2020, 09:40:48 AM

If I boot from DVD and run Linux Lite live the Wi-Fi light comes on and works.
I installed it to the hard drive because it worked.
But when I boot the installed version the Wi-Fi light does not turn on and
System Information does not detect the Wi-Fi card. Why doesn't the install
version configure itself like the DVD boot?

Hi

First guess is that the Wi-Fi driver is on the live boot not installed on the HDD.
Open a terminal windows and type this:
lspci | egrep -i --color 'network|ethernet'

Report back!
Bonus : I bet it's a broadcom Wi-Fi Card ;)

There is a specific driver to install in terminal for the broadcom BCM43xx :
sudo apt install firmware-b43-installer

If it does works, you could need some other steps. For that, see here :
