Hi,
Total newbie to linux and almost computer ignorant - please bear that in mind when answering. I recently installed Linux Mint 16 on my wifes computer after having so many viruses we could not remove on Windows 7. It is a 2013 HP Lapptop. The wireless signal is very weak and often disconnects. Not a good enough signal to stay online. I did some research and apparently this is a driver issue and specifics are required to solve it. I looked on the system info in Linux and here is what is says for the wireless driver:

This device is not working
Broadcom Corporation BM4313 802.11b/g/n Wireless LAN Controller

bcmwl-kernel-source
Version 6.30.223.141+bdcom-0umbuntu1
Broadcom 802.11 Linux STA wireless driver source

No Proprietary drivers are in use.

Please give me the kindegarten version of how to fix this. Wife is an internet addict and not happy with me right now!
Thanks!

1. Have you installed the broadcom-sta packages?
2. Do you know what driver is being used at the moment?
jdk

So when you were back on Windows, did the wireless connection work okay? If so it's definitely a driver problem. Personally I dislike any broadcom wireless hardware because I could barely ever get them to work. I have an old HP laptop where I replaced the mini-pci broadcom one with an Atheros-based card, never looked back. But I hear HP laptops have some evil junk bios code that prevents you from installing and using third party hardware, so I had to mod my bios as well.

I would suggest what jdkaye said, try installing the staging driver, and see what happens.

As you seem to have bcmwl-kernel-source installed, you should be able to simply activate the STA driverThis was taken from this document. Hopefully you won't need to remove any current drivers - post the output from this command
