drivers - WIFI scan without results Ubuntu 16.04 dualboot on Mac - Ask Ubuntu

i'm new ubuntu: have installed ubuntu 16.04 in dual boot on mid-2010 macbook pro.the installation seems have gone smoothly, have problem wifi, since wifi card doesn't find wifi when scanning. have checked , installed bcmwl-kernel-source according many other questions , websites(also ubuntu hel page) necessary driver wifi card have on, still nothing has changed , after 2 days og writing lots of things in shell try , resolve problem on own without success though i'd come , ask.

here find output of wireless info script. though might useful explain myself better http://pastebin.com/dggcatt3

you , have same wifi card. bcm4322 pci id 14e4:432b.

according chart, can try different driver. use sudo apt install broadcom-sta-dkms instead of bcmwl-kernel-source though both install wl (prop driver).

you can see chart our card partially supported b43 kernel agnostic.

if not having luck b43, i'd suggest reinstalling bcmwl kernel source or broadcom-sta-dkms (after purging or blacklisting b43 it).

" here how switch drivers (copied linuxwireless.org):

switching between drivers

if have few drivers installed, system may auto-load different driver 1 wanted use. manual (un)loading drivers can done modprobe tool.

to unload known drivers (you can pick 1 command, if know driver in use) perform:

toggle line numbers     1 modprobe -r b43 bcma    2 modprobe -r brcmsmac bcma    3 modprobe -r wl 

to load specific driver use 1 of following commands:

toggle line numbers     1 modprobe b43    2 modprobe brcmsmac    3 modprobe wl 

it possible prevent system auto-loading drivers blacklisting them. can done following command:

toggle line numbers     1 echo "blacklist drivername" >> /etc/modprobe.d/blacklist 

if plan use wl, should blacklist b43 , brcmsmac bcma. unfortunately wl not use bcma bus driver, additional step required. "
