networking - Broadcom BCM4352 Wireless not working with 16.10 - Ask Ubuntu

i believe i've tried proposed solutions other questions involving broadcom bcm4352 wifi hardware, on fresh install of ubuntu 16.10 on dell xps 13 9343 (2015) cannot system recognise device.

output of sudo lshw -c network:

secure boot disabled in bios:

wifi hardware not shown in network manager indicator:

i have selected bcmwl-kernel-source additional drivers application:

the wl module loaded , and have tried removing , reloading it.

i have tried unloading wl, uninstalling , purging bcmwl-kernel-source , installing firmware-b43-installer , b43-fwcutter, problem remains same.

the wireless hardware works in windows 10 , older versions of ubuntu until 16.04 there no question of hardware fault.

what else can try device working or debug problem?

we have found that, though blacklisted, bcma loads anyway!! let's correct in rc.local.

please do:

gksudo gedit /etc/systemd/system/rc-local.service 

put in following:

[unit]  description=/etc/rc.local compatibility  conditionpathexists=/etc/rc.local  [service]  type=forking  execstart=/etc/rc.local start  timeoutsec=0  standardoutput=tty  remainafterexit=yes  sysvstartpriority=99  [install]  wantedby=multi-user.target 

proofread carefully, save , close text editor. next:

gksudo gedit /etc/rc.local 

place following:

#!/bin/sh -e  modprobe -r wl modprobe -r bcma modprobe wl  exit 0 

proofread carefully, save , close text editor. next:

sudo chmod +rx /etc/rc.local  sudo systemctl enable rc-local  sudo systemctl start rc-local.service sudo systemctl status rc-local.service 

if there no errors, reboot , test.
