Wifi doesn't work on Ubuntu 14.04 LTS

Question

I have exactly the same problem of this question, however solution accepted as answer doesn't work. I also did all the commands in comment of that question but still no success.

The strange fact is when I use live cd of the same version of Ubuntu, I add the driver from "additional drivers". However after installing Ubuntu on HDD, in "additional drivers" I can find the missing driver(Broadcam Coporation:BCM4312 802.11b/g LP-PHY) which under the name,it is written that "the device is not working.". Selecting the driver and "Apply changes" wont also affect.
