I am running Ubuntu 12.04 LTS on my HP Pavilion g6-2220 as only OS. I have tried several ways, but still can't get my computer to understand the Wi-Fi button on/or even acknowledge it is there. Wired Internet works great, but the wireless will not function at all.

Any help on how to get my wireless up and running?

Please run lspci -nn and post the details of your wireless card. – chili555 Dec 28 '12 at 15:38

Install synaptic from Ubuntu software center.

select and install bcmwl-kernel-source and bcmwl-sta-source . That should install the Broadcom STA wireless driver. Hope it works!! :)
