Check type of wireless network adapter
A small tip to check the type of wireless network adapter:
$ lspci -k | grep -i "wireless"

For this wireless network adapter BCM4352, we need Broadcom wireless LAN driver (wl, aka broadcom-sta). The proprietary Broadcom wireless LAN driver (wl, aka broadcom-sta) provides support for some Broadcom-based PCI/PCIe hardware. It includes a binary-only component targeted for the x86 or x86-64 architecture. Supported devices are listed as follows:
Supported Devices : Broadcom BCM4311, BCM4312, BCM4313, BCM4321, BCM4322, BCM43224, BCM43225, BCM43227, BCM43228, BCM43142, BCM4331, BCM4352, BCM4360
wl installation
Add a “non-free” component to /etc/apt/sources.list
Add “non-free” component to the mirror file - /etc/apt/sources.list for your Debian version
# Debian 8 "Jessie"
deb http://httpredir.debian.org/debian/ jessie main contrib non-free
# Debian 9 "stretch"
deb http://httpredir.debian.org/debian/ stretch main contrib non-free
Install linux-image, linux-headers and broadcom-sta-dkms packages
# apt-get update
# apt-get install linux-image-$(uname -r|sed 's,[^-]*-[^-]*-,,') linux-headers-$(uname -r|sed 's,[^-]*-[^-]*-,,') broadcom-sta-dkms
This will also install the recommended wireless-tools package.
DKMS will build the wl module for your system.
Unload conflicting modules
# modprobe -r b44 b43 b43legacy ssb brcmsmac bcma
