My Laptop Hotspot is behaving too weird

I have a problem in making the laptop hotspot.
generally i use cmd for making hotspot by using hostednetwork commands. but now a days i'm facing a problem. when i try to start hostednetwork then on my laptop it shows the intenet access in my ssid nework but in my phone i can not use internet. i have also connected the other laptops through my hotspot.
In my laptop, i use microsoft security essential an no other softwares which harms the network sharing. i have also recovered my laptop and also updated my windows 7 too. i have also factory reset my mobile phone. but non of these experiments worked. i am very much tired of by doing all these stuff and it also wasted my so much time....
please try to solve my problem
