How to make my cellphone a router or a hotspot thing with a constraint My computer is connected to internet but I dont have a router(and I dont want to buy one) to use it on my phone. So I was using the usb "reverse tethering tool" which i could use succesfully. 

But now I want to use my phone as a router so that I can connect to internet from anywhere in my room with other phones.

And yes I dont want to buy a router, My PC doesnt have a wifi or bluetooth connectivity.

Thankyou for your time.

Sincerely,

Jasser

I am using samsung galaxy S duos GT-S7562.
You can turn your device into a Wifi Hotspot (there is an option in the general settings, usually with the other connectivity settings).

Generally, you will need to pay your Cellphone provider to allow you to use this particular feature (although there are ways to get around this - but that is another thread).

Bottom line, there is an option in the settings - if your phone can support this, you will easily be able to turn it on.
