Network Connection Not Available

[jeffcroskrey]

I am going to apologize upfront for this question, but I have researched for a couple hours on google, and on this forum, and I have tried some stuff, but nothing has worked.
So when I go to Network Connections, no wireless networks are available, and I have tried to add a network and it did not work, and I tried to install some drivers with some commands I found on another website, but that did not work. So here is the output of some of my commands....

lamborghini@lamborghini ~ $ inxi -N

Network: Card-1 Broadcom BCM4312 802.11b/g LP-PHY driver wl


So it seems like it is not a hardware problem because it recognizes the network card.....
What should I do next to connect to the internet?
