Please, tell us what's the Debian release you are using ("cat /etc/

Then you have to enable.
How do you enable/disable from windows? Is there a switch to turn it on/
off or are you using a software application for this task?
Run (as root): "rfkill list"

Okay, so the wifi adapter hardware is properly detected.

This can mean that the wifi switch is off so nothing triggers the wifi
adapter and so that kernel does not load the driver.

Okay, but this has to be automatically done. If you have a kernel module
loaded "by force" (manually) it does not mean the device will be working.
This module has to be loaded automatically, at system start up.

I agree. Indeed, you can use both, "b43" and "wl".

This is because the adpater seems to be "off" so GNOME cannot see it.

I would start by ensuring the wireless adapter is properly turned on
(wifi led button → green) so the system can automatically load the b43
kernel driver at booting.
