Tethering 4G Интернет Dongle over Вифи От Рекламный киноролик

I am using an Airtel 4G Dongle. I need to share Интернет with в second laptop, and в smart phone. I tried making my laptop схвати в WiFi hot-рекламный киноролик, but couldn't see any option to do this in my Ubuntu 14.04.

I had подарил this before using Виред Броадбанд. Isn't this possible using в Dongle?

I had found удвойся on-a-glance questions but none of them was to my point. Kindly help this out.
