Linux Mint 18.1 Serena
Installed mint properly, then as usual many times, the wi-fi card was not working - followed the instruction on the Mint Forum to configure the wi-fi network card - using Driver Manager -->additional drivers-->choosing the "bcmwl-kernel-source" as recommended (in my case bcm4322 from Macbook Pro 7.1 Model A1278, i have 3 machines) after choosing the additional driver, rebooting the machine finally the option to list wi-fi networks and configs appeared but, no ESSID listed, (i have 4 wi-fi networks enable including my neighbors ones).
After researching a lot (also changing the drivers to "firmware-b43-installer" and "firmware-b43legacy-installer to see if the problem was solved but no success, for 3 days using cable internet) to figure out why i have this issue with my broadcom cards from my Macbooks where no wi-fi networks are listed i recurred to Linux Mint IRC Help. One of the SysOps of the channel Rusty_1 and the users nevek, Mark_1, SimonNL and cryptonite helped me out for hours straight trying to figure out and changing a several settings and using dozens almost a hundred codes to analyze the issue, but nothing worked - no wi-fi got listed.
SOLUTION:
We returned to initial configs using the "bcmwl-kernel-source" driver as the Mint system recommended and when we were about to quit and i was bout to buy an usb wi-fi card the user Mark_1 from IRC found an internet post where a user using the same machine as mine.
The post said that to make things work, just install the Linux Mint Serena 18.1 on Macbook Pro as normal, add the "bcmwl-kernel-driver" as recommended using Driver Manager and reboot. After that we do the annoying secret step which makes the Broadcom works properly - SUSPEND THE OS AND THEM WAKE UP AGAIN - after this simple step the Broadcom starts lists the Networks properly and connects as a charm. But you have to do this (suspend and wake) every time you turn your on the machine.
Well, that's the problem/bug... that is not such a huge problem after days and hours of mIRC and help, but uses an annoying way to make things done every time you turn on your machine.
