The WiFi and Bluetooth connectivity for your laptop is almost certainly
all provided by the Broadcom chipset and the firmware it requires.

If not, it may be provided by the main laptop chipset - so maybe Intel?

You have been given (off list) a method for configuring kernel modules and
using DKMS to provide support when each kernel is updated.

You may need to download a firmware "blob" and place that in /lib/firmware

The method you've been given is by using module-assistant to automate
the process of building the kernel modules

So - you already have some of that in place: https://wiki.debian.org/wl

As root, you can run the command dmesg to see what the kernel finds at boot.
It produces a lot of output, so you can use grep to filter that.

What does the output of: 

dmesg | grep Bluetooth | less

produce for you - some of that should give you a clue as to what firmware
is found or is missing.
