I am having a hell of a time setting up my Wifi after a fresh install of Ubuntu 16.04 LTS on my MacBook Pro 8.1. Using the following command in terminal sudo lshw -C network I get the following returned to me:
*-network description: Wireless interface product: BCM4322 802.11a/b/g/n Wireless LAN Controller vendor: Broadcom Corporation physical id: 0 bus info: pci@0000:02:00.0 logical name: wlp2s0 version: 01 serial: 78:ca:39:b2:8e:4f width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=wl0 driverversion=6.30.223.271 (r587334) latency=0 multicast=yes wireless=IEEE 802.11 resources: irq:17 memory:d3200000-d3203fffInitially I went to my "Additional Drivers" and enabled the default Broadcom 802.11 driver which enabled my wifi but does not list all of the available networks. I tried to trouble shoot this error through the web and followed some answers on other askUbuntu posts but nothing works. Yes, I have tried installing the drivers manually for BCM4322 via bcmwl-kernel-source... documentation I used here. Any help would me much appreciated!!! I have no clue where to go from here.
