I have also had this problem (at least twice). I installed Linux Lite 2.0 on my Dell Vostro 1000 laptop. When it installs, it asked me if I wanted to connect to my WiFi with the "Broadcom 1390 WLAN MiniCard" and I did. Everything went well and I did quite a bit of work and rebooted several times with no problems. Then I found out about the Menue>Favorites>Update Software" and clicked it. The update seemed to go OK and it was fine until I rebooted. Then I had no Wifi. I didn't know whether the problem was the update or something I had done, so I re-installed from the CD and everything was fine again. I rebooted a couple of times to make sure the WiFi would come back and it did. Then I re-applied the update. It was fine, but when I rebooted the Wifi was gone. It certainly looks to me like something in the update crashed the driver.
I did try "Install Drivers" from the Settings and I saw a screen saying that the hardware was broken and a radio button was checked saying "don't use this hardware". There was another button that had a Broadcom driver listed (it was a Broadcom 1443 or something like that) with an unchecked radio button. I tried checking that and clicking "Apply", but when the screen refreshed it was unchecked again.
