I don't think there is a option in my laptop to create hotspot. As i am working with laptop from many years and i had not found such option to create Hotspot. As to use internet we need mobile hotspot or else how to get INTERNET if you are using WIFI and if dongle is used then better to go for the mobile hotspot to create your SIM card in proper use.
I instead prefer you to use your mobile or The local internet provider for best result so they also provide the service of hotspot and wifi facility so i think there will be no use of creating Hotspot in laptop .
Because there are some devices which already has Hotspot but using this feature in laptop is not available either you can go with mobile phone or broadband connection.
If you are using a dongle then prefer to remove simcard and put in your mobile phone and use the internt connection.
