Well this is how it happened and how i resolved the issue.
Before installing i started 16.04 live usb, the wifi was not working so in live usb i enabled proprietary wifi drivers from "additional drivers" the wifi had no problem from there on out, so i decided to continue with the installation of ubuntu, I selected the options i wanted and pressed to download updates while installing.
After it installed the ubuntu and booted in ubuntu i could not install wifi proprietary drivers even though i have managed to do so just fine on live usb. So at the end of the day i had to plug lan cable in the laptop and run -f install it downloaded software and after that the wifi started to function.
