My laptop (Dell Inspiron 17R 5720) came with preinstalled Ubuntu 11.10. I removed it and installed 12.04. Now I can't find driver for wireless. Apparently, in 11.10 there was Broadcom-STA driver. But in 12.04 there is no additional drivers to install. I tried using:
Well, I googled around and didn't find a thing for a basic Broadcom driver, I see everything else for all these multi-gigabit b/g/n drivers and all I want is a basic broadcom driver for my Dell laptop. I was able to use the same driver for my desktop with windows xp pro as with my 2004 laptop running windows 7. But still no avail for the same Linux driver.
