I believe I've tried all proposed solutions for other questions involving the Broadcom BCM4352 wifi hardware, but on a fresh install of Ubuntu 16.10 on a Dell XPS 13 9343 (2015) I cannot get the system to recognise the device.
sudo lshw -C network:

02:00.0 Network controller : Broadcom Limited BCM4352 802.11ac Wireless Network Adapter [14e4:43b1] (rev 03) Subsystem: Dell BCM4352 802.11ac Wireless Network Adapter [1028:0019] Kernel driver in use: bcma-pci-bridge Kernel modules: bcma, wl
Secure boot is disabled in the BIOS:
Wifi hardware is not shown in the Network Manager indicator:
I have selected
bcmwl-kernel-source from the additional drivers application:
wl module is loaded and and I have tried removing and reloading it.
I have also tried unloading
wl, uninstalling and purging
bcmwl-kernel-source and installing
b43-fwcutter, but the problem remains the same.
The wireless hardware works in Windows 10 and older versions of Ubuntu up until 16.04 so there is no question of a hardware fault.
What else can I try to get the device working or debug the problem?
