open CMD as admin
write the command:
netsh wlan set hostednetwork mode=allow ssid=SSID key=PASSWORD
this will create the hosted netwrok
SSID stands for the name you want for your wireless network (the name you'll see on your wifi networks on your phone).
PASSWORD is the network password you like to assign for your network.
then, write the command:
netsh wlan start hostednetwork
this will start the hosted network
then go to control panel>network and internet>network and sharing center>change adapter settings
there you will see your new hosted network
select your connection (from which you get your internet access from), go to properties>sharing. and then check share this connection with other... and select your new hosted network.
and you are done.
BTW, what what type of internet connection do you have?
