I recently clean installed LXLE 16.04 at my MacBook Pro 13" Mid 2010
Going through the previously asked questions I followed this guide here till the end.
Disabled (purged) the bcmwl-kernel-source driver and installed the firmware-b43-installer as recommended.
Followed the:
sudo modprobe -r b43
sudo modprobe b43
sudo rfkill unblock all
commands.
I blacklisted everything that has to do with bcm43 in blacklist.conf
blacklist b43
blacklist b43legacy
blacklist bcma
blacklist ndiswrapper
And added rfkill unblock wifi in /etc/rc.local
Still my Macbook Pro wifi card is occasionally working...(1/3rd of the times)
...usually I see no wifi networks although the card appears active.
I'm using my smartphone USB tethering option to share internet to my laptop.

Any ideas for a linux beginner?
Thank you
UPDATE 1: I think it might have something to do with power management. Quite often when in plug my wifi card scan's and shows the available wifi networks. When on battery , the wifi card is active but not scanning , not showing any available network.
UPDATE 2: I removed LXLE and clean installed Xubuntu 16.04. Installed 'bcmwl-kernel-source' driver from the "Additional Drivers" section. Still the same problem...the wifi card is installed but it is not scanning for wifi networks.
