Broadcom STA driver doesn’t work well with BCM4313
I have a Dell Laptop on which wireless is giving me problems.The card some times is detected and some times the card could not be detected.I noticed this problem started since I did suspend and resume of my laptop.
So I unistalled the Broadcomm STA driver and installed b43 then also things did not worked as expected.In a series of installation and unistallations of the wireless driver here things have got hotch potch.
The network icon on top right hand corner does not shows an option of wireless network. lspci -vnn shows following

An unsupported BCM4312 Low-Power (LP-PHY) device was found.
Use b43 LP-PHY firmware (firmware-b43-lpphy-installer package) instead.
Aborting.
There is no folder b43 in /lib/firmware (for firmware etc.)
I am not sure as right now which driver is loaded and which one is working.Is there a way that without formatting the entire thing I can get it back on track?
