Need help to get wifi connection ...

[Joe Lowder]

I finally got Linux Mint 18.1 installed on a
Thinkpad T430u (it should not be this hard)
but now I cannot get wifi connected.

Todd gave me some good tips, and I've searched
the 'net and found more tips, but still stuck.

I got this much:

command: lspci -vnn | grep 1434

result:
03:00.0 Network controller [0280]: Broadcom Corporation BCM43228
802.11a/b/g/n [14e4:4359]
Subsystem: Broadcom Corporation BCM43228 802.11a/b/g/n [14e4:0607]

I was then advised to check the driver support table at
linuxwireless.org (which is a non-existent website.

The "tip" said: "Once you confirm that your WLAN device is
supported, install the driver by running this command":

sudo apt-get install firmware-b43installer

Tried that and the result indicated that the driver was
installed ....... but now what?

How can I get this wifi connection to work?
