So, the short version of my sad story is that I tried upgrade Ubuntu to 12.04 and wireless driver has stopped working. I have tried all the solutions but nothing seem to be working.

When I try to install my wireless from "Additional Drivers" Its says: Sorry, installation of this driver failed. Please have a look at the log file for details: /var/log/jockey.log

The lspci command gives me the following info about wireless: 0c:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g LP-PHY (rev 01)

I have tried removing bcm drivers and reinstalling, but nothing seems to be working. rfkill is good too.
